What are types of abrasives?

Abrasive is a tool used for shaping or giving a fine finish to the workpiece by rubbing. By doing this, the friction wears away some part of the workpiece. It can also do the detailing of a workpiece, i.e. polishing to get a silky, smooth and shiny surface. Abrasives include a range of products from flap wheels to flap discs, and many things in between. It is commonly used in industrial, domestic, and technological applications. We offer this handy comparison chart to help you decide which abrasive will work best for your application for a quick look.

If you work with abrasives frequently, you already know you need different ones for different jobs. And JSH offers a variety of abrasives for every job, but how do you know which one to choose? Which abrasive grain is ideal for your application? Abrasives can be confusing and expensive, especially if you don’t know the ideal applications for each type. Here is a breakdown of the common types of abrasive grains, how they perform, how long they last and their ideal uses:


1. Abrasive Flap Wheels


Flap wheels are made of multiple abrasive sheets attached to a core for fabricating, deburring, cleaning, polishing, and finishing jobs in metalworking applications. The sheets wear away during jobs, constantly exposing the fresh abrasive coating to provide an even finish. The stainless-steel polishing flap wheel can be installed on the tube maker and the stainless-steel pipe polishing machine, and they have versatile flap wheel grit sizes.


Slashed flap wheels are widely used on the irregular surface of woodworks, soft metals, and also can be assembled for the auto polishing machine. We have introduced things you need to know about flap wheels in our recent article. Of course, if you need a refresher, you can check out our most recent blog, just to be sure.




2. Abrasive Belt


Industrial abrasive belts are mounted on rotating wheels or pulleys and are used in applications such as surface finishing, sanding, and grinding. Abrasive belt tools can be used throughout a body shop for a variety of sanding, blending, and finishing applications. It can be installed on the oil mill or the square tube drawing machine.

3. Cross Pads


Cross pads are a specialty abrasive made up of abrasive flaps folded over one another in a t-shape/plus sign/cross shape, which gets fitted onto a die grinder or rotary drill through a mandrel attachment. This product is made from sharp abrasive materials. It has a good elasticity feature and it is for easy replacement.


It’s a perfect material major used for polishing inner-wall of high qualified stainless-steel tuber and pipe fittings. Installed on the automatic polishing machine for stainless steel long pipes or elbows, used for polishing the inner wall of stainless steel long pipes and stainless steel long and short elbows, tees, etc.

4. Flap Disc

A flap disc set is an abrasive product designed for right-angle grinder applications that consist of overlapping abrasive “flaps” glued radially to a backing plate. The flap disc wheel has a long lifetime as calcined abrasive and zirconia alumina, better wear-resistant, self-sharpening, toughness, and hi-grinding power.




5. Flap wheel with shank


The flap wheel with shank by JSH is the ideal choice for polishing, flash removal, light grinding, deburring, scale removal, blending, and graining in small spaces, such as the inside or outside of pipes or tubes. Coordinate with pneumatic or electric hand grinder can polish metal or nonmetallic surface, variety of small gaps, slot seam which not easy to handle and the cavity parts.
