Things to Consider Before Buying Cut off Wheels
The shortlist above has already narrowed it down. To make it a bit easier, consider the factors below before choosing the best cutting wheel.
Safety first! Even though it is handy, the metal cutter is probably the most dangerous one of all the tools in your workshop. When cutting through metals, you don't want to lose some of your limbs in the process! So choose the one that can sustain the shear stress and don't spring back at you.
There are broadly two types of blades for the metal in shape. They are type 1 cutting wheel and type 27 cutting wheel. Both come with distinct advantages and drawbacks. You should choose any of these two types of electric wheels based on the nature of your task.
Type 1 Cut off Wheel
These are also known as type 41 metal cutters. For most general cutting operations, you'll find these cutters most handy. This type of electric wheel boasts the largest cutting surface. Thus they are extremely efficient.
If you intend to mount the wheel on a high-speed saw, a stationary saw, or maybe a chop saw, it will be a perfect choice. These metal cutters are also suitable for die grinders and grinders in general. You can easily perform 90-degree cuts by applying the cut off wheel to its maximum depth.
Type 27 Cut off Wheel
When the operator is working with restricted angles, these type 27 AKA type 42 metal cutters are needed. It should be noted, though; these cutters aren't best for cutting around profiles, extrusions, or corners.
The depression in the center achieves further addition of clearance. With the raised hub of this electric wheel, you can easily recess the locking nut and make a flush cut. The main advantage of these cutting wheels is the added visibility due to their depressed shape.
The materials determine the efficiency, durability, and reliability of a cut off tool it is made from. To get good performance, you must make sure that you buy blades for metal that have proper grain, bond, and fiberglass.
In a metal cutter, grains perform the actual cutting operation. In order to cut the hard-to-cut materials such as stainless steel, high nickel alloy, etc., you should use ceramic alumina grains. Generating less heat, these grains save the metal from getting discolored due to heat.
For fast, sharp cuts, use silicon carbide or aluminum oxide. Able to sustain the huge pressures, zirconia alumina grains can perform heavy-duty jobs such as rail cutting and cutting of structural steel.
Bonds on the cut off wheel keep the abrasives in their places. Bonds can be softer or harder. It determines the tenacity with which the grains are implanted on the plate; thus, the lifespan of the metal cutters also depends on the bond strength.
Hard bonds prolong the lifespan of the cutter. Soft ones are good for fast cuts as they quickly shade the worn-out grains. Resined bonds can withstand heavy shocks. Finally, resin-over-resin bonds are for better cooling.
Blades for metal contain fiberglass to add reinforcement to the cutter structure. The more layers of fiberglass are there, the stronger the cut off wheel. Multiple layers are used for high-performance, industrial purposes, whereas the single-layered ones are good for high speed.
Finally, you should consider the size of the cut off tools you're buying. Size has two primary aspects: diameter and thickness. The larger the diameter, the higher the metal cutter's RPM rate. Thickness determines how fine the cutter can perform a cut.
How to Use a Cut off Wheel?
Here are some tips on using a cut-off wheel safely.
Take Safety Measures
Safety first, so first, put on the protection gear: goggles, gloves, shield, and all. For regular use, we recommend aprons and masks as well. It may seem to be an exaggeration, but they'll save you a lot of trouble in the long run.
Avoid Damaged Blades
Make sure you don't use damaged blade cutting. A defective cutter can ruin your workpiece, or even worse, ruin you! Secure the metal cutter with flanges, clamp-lock the job, and you're good to go. Oh, one more thing, no matter what you do, doesn't operate without a wheel guard.
Don't Use any Brutal Force
One common mistake is trying to force the cut-off wheel through the metal. You must make sure you don't make this mistake by being tempted to make a fast cut. If too much pressure is applied, it will generate excessive heat.
Premature heat buildup will degrade the cutting ability of the metal cutter and slow down the process. This also cuts short the lifespan of the wheel. To make the most out of your time, you need to push the cut-off tool with just enough pressure so that it feeds itself into the workpiece.
Frequently Asked Questions
1. Which type of cut-off wheel should I use?
It depends on the job at hand. You should use cutters with aluminum oxide grains for most general use purposes. It's very easy to get your hands on them, sold everywhere. You can use these to cut steel and most other metals. You'll also get a good initial removal rate.
For machining stainless steel and the toughest cast irons, you may use blades coated with cubic boron nitride. Non-metals, nonferrous metals, etc. will easily get sawed off by silicon carbide blades. The king of the metal cutters is diamond grained wheels. Use accordingly.
2. How do I install a metal cutter?
First, choose the right one for the job. Inspect it carefully for defects. Beware! This is an issue of life and death. If there isn't any scar on the wheel, reach for the wrench. Remove the nut of the arbor and place the cutter carefully.
Once you've placed the wheel, put the bolt back to its position and secure it and the electric wheel with the nut. Make sure you tighten up the nut and bolt. Otherwise, you'll put yourself in great danger.
3. Is the higher the RPM, the better the performance?
No, not necessarily. It's true that if all things remain the same, the material removal rate, i.e. the rate of cutting, will be proportional to the rate of rotation of the wheel. But as you may have guessed by now, everything else simply doesn't remain the same.
Too high RPM may cause structural damage to the cut-off tool and cause it to crack. At higher RPMs, it becomes difficult for you to handle the cutter. High speed will generate more heat and cut back on efficiency.
4. How do I get the most out of my effort?
When it comes to handling the blades for metal cutting, here are two rules of thumb you should follow:
- Firstly, position the wheel at an angle of 90 degrees with the surface of the workpiece. This will result in the most feeding.
- Hold the cut-of feel gently against the job. Don't push hard. Let the cutter feed itself through the material. If you push it too far, it may spring back.
5. How should the cut-off wheel be stored?
Like most other items, they should be kept clean and in a dry place. To avoid premature wearing or cracking, you must keep the cut-off tool safe from elemental damage.
There you are; you've come to the end of the road. In our search for the best of the best cut-off wheels, we've dug out 10 of the most outstanding blades for metal cutting. But if you're feeling a bit confused, here's a brief suggestion for you.
For an overall experience, you can go for the DEWALT General Purpose Metal Cutting Wheel. Moreover, the Weiler Wolverine Flat Cut-Off Wheel and LENOX Tools Diamond Edge Metal Cutting Wheel are some other excellent options that come with outstanding functionality and durability.
