What is an Angle Grinder?

Angle grinders are versatile tools that can be used in a variety of tasks including cutting metal surfaces, removing loose paint from walls, shaping small tiles and sharpening mower blades just to mention a few. These devices come fitted with a pair of detachable grinding wheels that also make them easy to use for a variety of tasks around the home.

Nevertheless, before starting any work it’s always important to know what you’ll be using the equipment for so as to prepare well in advance. This way you’ll also be able to choose the most appropriate type of grinder for the job. When used correctly, this machine can help you finish multiple tasks in record time.

Where to buy

The angle grinder can be found in most hardware stores where power tools are being sold. There are large versions available but the most popular ones are 4 and 4.5 inch grinders, they are perfectly sized for most tasks. Though you can buy costly high-end models, for frequent demanding home tasks such as cutting cement or stucco look for those with powerful motors of between 5 to 9 amps.

A machine’s ability to accommodate different accessories and wheels is also important, versatile equipment should preferably include items such as spindle nut and spindle washer for better functionality. These can be installed in varying configuration settings to accommodate thinner or thicker wheels, depending on what the device is running on. Even so, before screwing in wire wheels or cups onto the grinder’s threaded spindle, first consult with your instructions manual for more information on how to go about this task.

When shopping for them at the hardware store you may find that abrasive wheels look quite similar, but don’t be confused as they are designed to perform different roles.

How to use it

I. Choose a machine that’s best suited for the project at hand. Generally, electric models pack more power and are best suited for large-scale jobs that cover immense surface areas. On the other hand, pneumatic grinders are much less powerful, but still easier to operate and suitable for lighter jobs in tight fitting spaces.

II. Pick appropriate discs. Polishing pads and sanding discs are typically used for finishing tasks, while cutting discs will be more useful in masonry, cutting tile, removing rust/paint and resizing steel or pipes.

III. Secure your work material firmly onto a stable surface and ensure the guard is well fitted. Note that grinding discs can also be used for milling stone and metal, but in whatever you do never try using a slicing disc for performing grinding work.

IV. Hold the machine down with a strong grip preferably against the weight of your body, rather than handling it from the edge. Next, move your grinder towards the handle’s direction to prevent it from kicking back or the disc slipping from its position. This may ruin your job and even cause injury so be careful.

V. Finally, when grinding work is complete lift off the shredder from the surface slowly and store in a safe dry place away from direct sunlight.

Safety tips

When pulverizing metal always apply light pressure to prevent overheating the material. Additionally, keep a small bucket of water and rag nearby to occasionally moist the metal so that it can remain cool as you continue grinding. Remember to always unplug the grinder when changing wheels so as to avoid kickback, similarly sometimes milling can cause sparks so try working at a safe distance away from inflammable materials.

Use the machine guard whenever possible as this will prevent minor injuries. Furthermore, never wear loose apparels or headphones which can easily get caught inside the angle grinder. All in all exercise proper safety precautions and leave nothing to chance. The most common injuries that affect people using this device are on the head and face, therefore wear appropriate face shield or safety goggles and heavy-duty work gloves. Other things you may need are earmuffs and sealed respirator facial mask, this will protect one from inhaling dust particles or metal shaving that may be produced as residue from the worksite. In general, angle grinders are commonly used in construction and metalwork tasks as well as emergency rescue operations. They are usually found in workshops, auto-body repair shops and even service garages.

What is a Band Saw?

Though rare compared to other power tools found in the market today, a band saw can be very useful in cutting precise curves in wood. The machine is often applied in chopping down stock to sizable chunks and smoothening out rough timber edges. It contains a sharp serrated blade that runs inside a single continuous loop, this razor edge measures a mere 0.25 inches wide but has immense potential despite its dimensions.

Common types of band saws

Currently, there are 2 main types of band saws available for purchase which include, floor-standing cabinet models and those that are much shorter. These smaller units can be mounted either upon a bench top or dedicated stand unit. The cabinet models are usually meant for professional industrial use, whereas their counterparts are better suited for homebased woodwork chores.

Furthermore, the first option typically has more features and even a larger motor unit, including a stronger frame which delivers consistent cutting with each single stroke. However, that doesn’t mean one can’t get quality professional results from using a standard bench-mounted band saw.

Blade installation

There are various types of blades that can be used for this device. Which vary considerably in terms of size, razor material and tooth shape. If you’re not sure of the particular blade to use for a certain task then seek reference from your manufacturer’s handbook documentation.

The fabrics to be cut should measure at least thrice the width and thickness of your chopping blades. Hence, it’s always best to cut thin sheets using a shear rather than bandsaw. When a proper blade is identified, it can be resized to a good length and welded to form a single continuous band. This is done using a special electrical resistance welder constructed into the saw.

Both upper and lower doors open gently exposing the pulleys lying inside, moreover a tensioner allows the upmost pulley to be raised or lowered depending on the task at hand. Lowering of upper winch also makes it easier for one to put up a new blade, the razor must be set up properly into the upper/lower blade guides. Once fitted into position, proper tension should be set then locked.

Key features

The two main factors to consider when looking for a suitable band saw are depth of cut and throat length. The machine’s cutting depth refers to distance from table top to upper blade guides. Many band saws today are marketed as having this feature alone, telling prospective buyers which particular stock thickness levels can be sliced using the machine.

However, saws that only have a 6-inch deep cut may also feature an optional riser fitted onto the unit, this readily extends its depth from 6 inches to 12 for a more comfortable fit. It also allows less expensive blades to server much thicker stock, especially when re-sawing.

Saw throat refers to the average distance from blade to vertical frame section of your device’s body. This dimension determines the overall width-of-cut that can be achieved on the machine. Moreover, the throat on any free-standing cabinet unit typically exceeds 12 to 14 inch length found in bench-top models. Whenever you see the term ’18’’ Band Saw’ advertised, then know it’s the throat measurement that your manufacturer is talking about.

Using a band saw

Before turning the machine on, first adjust its blade guide/guard to an appropriate height. The less razor edge exposed, the safer you’ll be. Always set your blade guide at an appropriate height, high enough to sufficiently clear the part that you are cutting.

Note that appropriate cutting speeds will vary from one instance to another, depending on the particular task at hand. For instance, moderately thick steel should be sliced at lower speeds compared to aluminum alloys. ‘Job Selector Dial’ can also help you choose an appropriate motor speed for completing the task at hand. To adjust blade tempo your motor should always be turned on. Similarly, motor speed can be regulated depending on the variable dial control reading, while rpm is strictly monitored based on speed indicator gauge.

When cutting any material with a bandsaw, proper technique should be applied. Don’t lean excessively into the task but instead keep your hands fully braced against the worktable. One key feature of this machine is its ability to make precise shapes. Nevertheless, when operating always watch out for proper positioning of your hands on the clip to avoid injury.

What is a Chainsaw?

What is A Chainsaw?

The chainsaw is a powerful tool used for chopping down trees and logs. It consists of two main parts which include an inbuilt saw blade draped around a long metallic guide bar, and small gasoline cylinder or electric motor for those that run on power. The chain resembles that of a bicycle running on sprockets, but with around 30 sharp teeth fitted around it at even sections.

It has an engine that pushes the piston in and out of its cylinder, rotating a connection rod responsible for turning an internal crankshaft unit. This consequently moves gears that are directly connected to a sprocket supporting the mounted chain, making it spin around.

How to use the machine

I. To start your chainsaw from a cold engine standpoint, first place it on a level ground then push your chain brake forward until it actively engages. Corded chainsaw models require a suitable extension cable. Always follow the manufacturer’s instructions when picking compatible extension cables

II. Pull start/choke control unit onto ON position. Then push decompression valve and primer bulb approximately 6 times. While doing this, hold your device’s front handle with the left hand and put one foot on top of the rear handle.

III. Pull starter handle using your right hand until it fires up, afterwards push the choke in then try pulling up again. Once the machine picks speed, squeeze your throttle accordingly to disengage high idle mode. The chainsaw is now ready for use. To stop movement simply switch off its ignition key.

Safety considerations

Since chainsaw blades are very sharp and can cut almost anything that comes into their way, users should be extra careful when handling them so as to avoid getting serious injuries. You can cut with either the top or bottom part of your machine but always avoid ‘kickback zone’, which is 90-degrees from the front central point upwards.

Use it with chain section facing downwards from the handle bar, it’s a common practice and feels very natural as well. This way your saw pulls gently and is also easy to direct by maintaining a steady grip. Nevertheless, cutting a branch from its underside will require that you use the chainsaw’s top section. This can be somewhat unnerving since the blade pushes towards you. That’s why most modern devices are nowadays equipped with automatic braking systems, which help in stopping movement when a kickback happens.

Additionally, always remember to put on your safety apparatus before turning on this equipment. There are special chaps that can stop any moving chain from causing injury and save your thighs from being severed. A helmet with face screen and ear protection can keep your head, eyes and ears well protected from flying debris of all manner. Similarly, steel-toed, cut resistant boots as well as a long-sleeved shirt will protect the skin from inevitable scratches.

When moving from one place to another with a running chainsaw on hand, even if it’s just a few meters, always remove the right hand from its back handle and carry from your side with left hand holding tightly onto the front bar. This way in case of an accidental trip or stumble the engine will not accelerate and make your chain spin uncontrollably.

Maintenance tips

Chainsaws must be properly maintained in order to remain sharp and accurate. Before performing any maintenance work, first turn off the machine by disconnecting spark plug on gas-powered models and electric power source in mechanical saws. Check air filter to ensure it’s clean and replace if necessary, also look at chain tension and adjust accordingly if needed. Likewise, inspect operations of the chain brake, oiler, throttle lockout and chain catcher.

It’s always best to search for the most reliable chainsaw and in this case there are many chainsaw reviews available to read through.

Summary

Most people prefer using chainsaws over other cutting tools when chopping down timber since they are fast. Handsaws, axes and other related machines are also not efficient and leave rough edges behind after a cut has been made. Chainsaws on the other hand have very smooth finishes.

In fact, studies show that these machines are approximately 5-10 times faster than other ordinary handheld saws. Which means operators can complete tasks much quicker, and with minimal effort. Moreover, with proper care and maintenance they can serve you for many years to come without requiring any major repairs that might otherwise be expensive. When buying note that these devices vary in terms of size and torque power.

What Is A Power Drill?

The power drill is an electric machine fitted with a rotary motor and replaceable drill part for burrowing holes in metal, wood or plastic materials. Similarly, a screwdriver head can be installed to move screws. This tool consists of different parts that work together in a well-coordinated manner. They include the handle grip, on/off safety latch trigger, torque adjustment knob, holding chuck and reversal switch for changing direction of the drill unit.

Corded drills are run by a 110 volt motor cable inserted inside an electrical receptacle. Alternatively, battery-operated drills are driven by a cell unit found in the machine’s handle. These devices are handy tools for performing various tasks around the home, such as installing wall frames and making furniture.

Types of drill bits

Drill bits come in different suitable designs depending on the material they would be used for. Nevertheless, the most common version is a general-purpose machine with simple head. It can be used for most household chores whether simple or tasking. Other popular models include brad point, diamond carbide tip, masonry and flat/spade bits for light wood framing.

When drilling holes on any surface, always ensure that you’re using the right sized bit. To verify this, hold up the screw with its burrowing end in front. If everything is okay then you should see all of your screw’s threads running behind the whole cutting bit. This simply means that the drill bit should have the same dimension as your machine’s body, though slightly smaller than its threads.

Moreover, when drilling large holes especially in metal surfaces, or with a sharp center point. You may first have to dig a smaller ‘test hole’ to help guide your drill and safeguard the material from cracking up. Nowadays, there are special bits which are designed to do this particular task for you automatically. But they are quite rare to come by.

How to use the machine safely

i) First, make sure that your drill switch is turned off before starting, or the electrical cord is unplugged. This will prevent power jolts that could potentially be dangerous.

ii) Next, loosen its chuck and fit in an appropriate tip shaft, then tighten it up again. Note that some power drills may require a special equipment to firmly secure the chuck.

iii) Set your torque adjuster to control slippage on the drill bit, this is useful when rotating screws without damaging its bolt head. Insert battery into power drill then fit the point of your screwdriver or burrowing bit as required.

iv) Press on safety latch and then the on/off trigger. Finally, push your drill bit head forward as the machine chuck slowly rotates.

Usually, the torque in most drills is set at its lowest point so as to tighten screw until a sufficient tension is reached. Avoid tightening it completely as this can strip screw surface, or even poke your eyes out when ejected forcefully during motor movement. Preferably start with a low-to-medium torque level then adjust accordingly, depending on overall intensity of work at hand.

Precautions

As much as power drills can be helpful, users still need to take certain precautionary measures since they can cause damage when not properly controlled. Always be careful when operating them and wear proper eye protection since some bits may accidentally shoot up and cause unnecessary injury.

Moreover, when drilling materials always remember that you can make the hole larger but never smaller. Therefore, if you’re not sure on which particular size drill unit to use, it would be better to go for a smaller one and make necessary changes later on if required. Instead of choosing a large-sized bit that makes irreversible holes.

Also, when making holes in drywall ensure that you use plastic anchors for support. Sometimes the tiny sharp threads found in screws are too fine for the coarse chalky composition of a drywall. Plastic ‘threaders’ are sufficiently big and elastic, they can hold onto drywall surfaces much better than bare screws.

Though power drills require little maintenance, they can still get damaged from improper use. Such as operating using the wrong tip or drill bit, something that can occasionally lug down and destroy the motor. These tools are indispensable to any serious DIY enthusiast making life a whole lot better, they can be bought from your nearest hardware store or even trusted online dealers.
