What Is the Right Grinder Disk for Your Job?
What type of disk will you need for the job? This is a question that every angle grinder operator should ask before starting on a job. Your choice in a disc will affect your safety and efficiency on the job. You must then carefully consider the uses of each type of disc.

These are expendable tools used in cutting a wide range of materials. These are usually round, thin and flat panels like CDs but with sharp edges. These are commonly used on metal alloys, wood, stone, tiles and concrete.
When correctly used, cutting discs allow the angle grinder operation more mobility and versatility. You can cut stainless steel rods, steel pipes, and aluminum profiles with more ease.
Cutting with it results in the complete reduction of the material’s total length. This is because the disc removes part of the material from a given point. The cut part has a hole that separates the material in several pieces of the desired length.
The cutting process also involves the ultra-rapid honing of the material. The speed of several thousand revolutions per minute is applied on a tiny area (i.e., 0.8 to 3mm).
In theory, you can use a grinding disc in cutting certain materials. But you will likely waste time, power and material. You should always use a cutting disk for cutting jobs, period.
When choosing a disk, use the thinnest possible disk. Be careful also about cutting the material so it doesn’t overheat. Cutting generates high levels of friction resulting in unwanted changes in the material.
Why a thin disk? The thinner the disk, the more accurate and faster the job can be finished. Thin cutting disks (1.00 mm thick) also have these advantages:
But don’t dismiss the thicker 3.00 mm thick cutting disks, too. These classic cutting disks have several advantages including more affordable prices and longer lifetimes. You may also prefer them out of habit.
The cutting mixture include aluminum oxide, corundum, and silicon carbide (SiC), among others. The disc also has two safety nets as the standard.
Second, cutting discs with diamonds incorporated in their design. These can be used for both cutting and grinding a wide range of materials from steel to stone.
You will also find that diamond discs are quicker, easier and safer to use. These grind faster than grit discs and safer to use, thanks to the nil chances of the disc falling off. Your higher investment will be well worth the cost, indeed.
Best Flap Discs
These are made of several overlapping pieces of abrasives that form flaps. You can use them for a wide range of uses. These include heavy stock removal, surface blending, and final finishing.
Flap discs have many advantages including:
Flap discs are increasingly becoming popular because of their cost efficiency and results effectiveness. These have longer operating lives and, thus, are cheaper in the long run.
Best Grit Discs
These are the most affordable options among angle grinder discs. You can use grit discs for cutting certain substances, such as metal and stone. You may also use them for grinding these materials although the right grit is a must.
There are also several advantages of grit discs over other types including:
Second, wood discs are suitable only for wood applications. The best type is arbortech because it can cut through wood and steel (i.e., nails).
Always be sure to choose the right disc for the job. Your safety and efficiency partly depends making the right choice in angle grinder attachments.
The right choice in an angle grinder disc depends on several factors. You have to consider the type of material and the desired results from it. You must also consider the size, power and grit of the disc in relation to the material.
The disc on an angle grinder can make or break the material for grinding, cutting, or polishing. The results of the job will be affected by the disc choice for many reasons, too.
Keep in mind that the disc comes into direct contact with the material. The disc can either do its job well or not depending on its suitability for the job at hand.
