A power tool, in principle, uses a motor that runs on electricity or compressed air. It may also use an engine running on gasoline. A power tool can be used in households, factories and for construction purposes.

Most power tools used today run on electric motors and are also known as electric power tools. Electric power tools are more effective and help you do work faster but you need to keep in mind the safety precautions while working with these tools.

A power tool can be of two types:

Stationery: These are quite heavy and big and cannot be easily moved from one place to another. They have an advantage over the portable tools that they are faster in terms of speed and more precise and accurate than the handheld counterparts. The disadvantages obviously are the space being used by them and the expense that goes into buying and maintaining these power tools. Many times, people prefer hiring these tools rather than buying them.

Portable: A portable power tool is usually a handheld device and can be easily carried from one place to another. The cost-effectiveness, easy maintenance and small shelf space requirement have made a portable power tool more popular over the stationery ones.

Power tools include:
Wall chaser: A power tool used to cut out a thin groove in the wall.
Sander: A power tool used like a sand paper to smoothen the rough edges of wood.
Nail gun: A tool used in place of hammer to insert nails in wood or in wall.
Table saw: An electric power tool, which is stationary and is used to cut wood into even pieces.
Diamond tool: A power tool, which contains segments of diamond to cut different materials.

It is very important to check for branded and quality products when you are buying electric power tools as you may risk your life by not doing so. It is also important to use an electric power tool intelligently in order to protect its motor.

A power tool helps you to finish your task quickly, effectively and easily.

When most people hear the word diamond they conjure up in their head very expensive clear stones that they have only seen on jewelry. That because what so many people don’t realize is that industrial grade diamonds are being used on more cutting a drilling tools then they ever have in the past. The reason for this is simple and that’s that industrial grade diamonds are now cheaper to buy then they have ever been before.

Today Industrial Grade Black Diamonds are Being Synthesized

You see, it wasn’t that many years back when all diamonds had to be mined from the ground. High grade clear diamonds went to jewelers and lower grade black diamonds went to tool makers. Then something happened that drastically effected the cost and availability of industrial tool grade diamonds. They began to be synthesized.

The Best Type Of Tools For Cutting Stone and Cement

So what exactly is the benefit of diamond drilling tools? Well, there are several benefits but the first one it that they are the most effective means to drill or cut through stone, masonry or concrete. Not only do they do the job much faster but they allow allow for a much more cleaner or precision end result.

Diamond Drilling Tools Never Have To Be Sharpened

Still one more benefit is that diamond drilling and cutting tools don’t have to be sharpened, because they cut or drill just as well on their first day as on their last. You see, all that you have to do is examine the quantity and condition of the diamonds on the tip or edges to see if a diamond drilling or cutting tool is still viable.

Both Wet and Dry Drills and Saws

Diamond drills and cutters can be used with or without water, depending on the type that you purchase. In general however, the larger and more heavy duty drill and saws will require water to be used with them as a coolant. Never ever use a wet diamond cutting or drilling tool dry or it will be ruined in very short order.

Want To Try Them? – Find Them At Any Rental Yard

If you’ve never before used a diamond cutting or drilling tool then one great idea is to head on down to your local rental yard and rent one to try them out. However; be aware that not only will you pay a daily rental fee for your diamond tool but they will also measure the amount of wear on the diamonds when you return it and charge you accordingly.

A great Way To get the Feel Of Diamond Drills and saws

Even so, its a great way to get a feel for this type of precision high tech line of tools before you decide on what best suits your needs on a job site. Remember that they are considerably more expensive than hardened steel and carbide drilling and cutting tools so in the long run this can save you some money.

Wear All Your Safety Gear When Using Them

One more thing to bear in mind when using diamond drilling or cutting tools is that they can be more dangerous for a few reasons. For starters they do tend to kick up more dust, due to their higher level of efficiency. Also they can spin a lot faster as they don’t rely in impacts to bore such as an impact drill does. So needless to say goggles, ear plugs and gloves are a must!

Diamond tools or any other power tools for can be potentially dangerous if not used correctly. This article will touch base on a few of the do’s and don’ts of general diamond saw blade usage.

Things you should check before you begin cutting.

(Always wear proper safety equipment)

1. Make sure the diamond blade has no damage to it (shipping or previous use) before mounting on your saw.

2. Make sure the arrow indicates the correct rotation direction when mounting on the saw, if you put a diamond blade on backwards the efficiency will be greatly reduced and you will not get the full life out of the saw blade.

3. Tighten the flanges (plates that hold the diamond blade on the crank shaft) to avoid the blade from slipping during the cut and to ensure full cutting performance.

4. If you are using a wet cutting saw, make sure the waterways are clean and unobstructed to prevent overheating of the diamond blade and to clear the cut of any slurry. (cutting material left behind during the cutting process)

5. Make sure you know the correct RPM speed of the blade and use the saw accordingly.

6. Wear respiratory safety gear to avoid breathing any potentially hazardrous air born dust cause by cutting. (Even when wet cutting, it is always recommended to wear all the proper safety equipment)

7. Make sure the diamond blade still has cutting segments! All diamond blades have a welding line, whether it be laser welded or sintered there is always about 1mm of useless segments. Check your diamond blade periodically when you notice the segments are nearly worn. By cutting with useless segments you can damage your cutting saw.

Tips to ensure correct cutting procedures.

1. Make sure your saw has proper maintenance: Check the flanges, crank shaft (arbor), bearings, belts, filters, oil, etc.

2. Make sure your cutting saw’s arbor shaft spins on a true axis. A shaft than has any type of wobbling will greatly reduce the life of your diamond tool.

3. Use light to medium pressure when cutting, allow the diamond blade to push through the material at a safe speed.

4. Never apply excessive pressure or you may overheat the diamond blade or worse yet, throw a segment which can be potentially fatal considering the RPMs at which the saw runs.

5. Make sure your time blade has enough diamonds protruding on the surface or it will not cut effectively. Common cause of this is cutting a material that is too hard for the diamond blade’s bond. You can cut highly abrasive materials to resharpen the diamond blade, such as asphalt or abrasive cinderblock.

6. Make shallow cuts in the material you are cutting. For example, if you need to cut 4 inches deep you should cut in 2 passes. The 1st pass at 2″ deep and the second pass at the full 4″ depth to avoid overheating and extend the diamond blade’s life duration significantly.

7. Never use a diamond blade for grinding materials. A diamond blade should ONLY be used to make straight cuts, if you try to cut in curves it is very likely that the diamond blade will get stuck or break a segment and send it flying at dangerous speeds. At the very least, the blade will wear unevenly and overheat (since the diamond segments lose their width they also lose their potential to retain heat, thinner objects overheat much faster)

8. Make sure the diamond blade isn’t bent, this is a hazard since it could get caught in the cut and throw segments.

9. Never stand in front of the saw, it can send the cutting material forth at high speeds and potentially cause injury.

10. Use the diamond blade only on materials it is specifically manufactured for. Using the wrong diamond blade on specific materials can cause segment loss, smoothing of the segments (causing it to cut very slow and ineffective), extremely fast wear or not cut at all.

If you follow these simple steps you’ll save time and money through the effective use of diamond blades and save yourself lots of grief or possibly injury in worst case scenarios

Thanks for reading, good luck on your upcoming cutting projects!

Diamond Tool Information – Diamond Blades – Core Bits – Grinding Cups

Diamond saw blades are generally used for cutting concrete, asphalt, brick, block, stone, tile, ceramics, porcelain and other similar materials. Saw blades are usually used by contractors or home owners for DIY (do it yourself) projects, home improvements, repairs, building construction and restoration.

There is a large variety of saw blades designed for different cutting materials. When choosing your diamond blade it is extremely important that you know the material well. Selecting the wrong saw blade for your cutting application will result in poor performance, premature wear and possible damage to the blade, saw or operator.

Diamond blades are designed for different cutting materials depending on the abrasive properties and how hard the materials are that need to be cut. For soft abrasives such as asphalt, you will need a specific asphalt saw blade. These asphalt diamond blades typically have wider U-shaped gullets (spaces between segments) to help remove the slurry (abrasive leftover materials from the cut) faster to prevent premature wear beneath the segments. The premature wear under the segments is known as “Under Cutting” and it can lead to possible segment loss of the diamond blade.

To prevent undercutting, asphalt blades typically have a drop segments (multiple taller segments to distribute the slurry away from the segment supports) or small carbide or diamond inserts between some of the gullets. Another reason it is important to choose the right blade for cutting asphalt is the diamond blade’s bond.

Diamond blades for cutting concrete are quite the opposite of asphalt blades. They have narrow key slot shaped segments for smoother cutting of hard materials. Since cured concrete is a hard material, the diamond blade will need a soft bond for a faster wear rate. If the bond is too hard for the material you’re trying to cut, the diamonds will glaze over and become smooth. Smoothing of the diamonds will cause the diamond blade to stop cutting effectively or completely and more importantly it can cause damage to you, your equipment or the blade itself.

A few ways you can avoid this is by checking the blade from time to time, making sure the segments still feel rough to the touch. This assures that sharp diamonds are exposed on the cutting surface and everything is working fine. If the segments feel smooth then you should use a softer bond for your cutting material which means that the segments should wear down faster allowing new diamonds to be exposed quicker and allow the worn diamonds to fall out.

If you make short cuts in a softer abrasive material it will “sharpen” the blade by wearing down the segments quickly. It’s recommendable however that you acquire a different blade instead of trying to reuse the current one as the same situation will occur.
Diamond blades are commonly use on gas powered high speed cutoff saws, handheld electric angle grinders, walk behind floor saws, table mounted saws and rail saws to name a few.

Some diamond blades have very specific uses such as concave diamond blades for cutting curves or tuck pointers for removing old mortar for brick wall repairs.
Other similar diamond tools are core drill bits and grinding cup wheels for concrete.

A core bit is a long tube with diamond segments on the tip used for drilling concrete, stone or other masonry materials. Make sure to choose the right dry or wet cutting core bit for your cutting equipment.

Grinding cup wheels are cup shaped wheels with diamond segments for grinding or polishing concrete and stone. There are various types of segment designs depending on the desired finish.

For fast aggressive removal of concrete you should use a turbo segment or double row grinding cup. For a smoother finish you should use a full turbo grinding cup with the largest segment surface area possible.

Always remember to wear proper safety equipment to protect yourself and make sure you have a well ventilated work space to avoid breathing harmful air born dust caused by the cutting materials. Be sure to maintain your cutting equipment and check it periodically to ensure fast cutting and proper distribution of water flow.

Angle Grinder

They range from diamond saw blades, grinding cup wheels and diamond tipped core bits in general.

They are commonly used for cutting concrete, cutting asphalt, reinforced concrete, fresh concrete, tile, glass, brick, block, stone and other masonry materials.
