Non-Woven Flap Wheel

The porous, non-woven structure promotes airflow and resists loading which prolongs the useful life of the wheel

 and reduces heat buildup which may stain or distort workpieces. The interleaf flap drum is able to clean, blend

and finish while keeping the workpiece intact and offers a greater sanding surface area compared interleaf flap 

discs for angle grinders.

This wheel is manufactured using a “web” of nylon fibers that are bonded together (not woven together – hence 

the name) with synthetic resins. The fibers are impregnated with abrasive grain, producing a cushioned, three-

dimensional material that is pliable, conformable to the workpiece, and long-lasting. Non-woven abrasives can be

 the ideal grinding products for deburring, cleaning, and imparting the desired finish to a wide variety of materials.

 A basic understanding of how these products are made, and how they should be selected and used to their 

maximum benefit, can help the metalworking manufacturer achieve the desired surface finish.

Why there?

The relatively non-aggressive nature of nylon and the abrasive grit used in non-wovens make them excellent 

finishing tools. With their open-mesh construction, non-wovens are waterproof, washable, and resilient. They 

resist loading and rusting, and are not conducive. In the standard non-woven design, the abrasive grain is 

uniformly dispersed throughout the nylon web, providing a continuous supply of new grain as the old grain and 

fibers wear away during use. While 60 grit to 80 grit abrasives is considered intermediate sizes in other products, 

they are considered coarse for non-woven products. Non-wovens can be used on a range of metals, including 

aluminum, brass, copper, nickel, chrome plate, stainless steel, and titanium, as well as other hard-to-grind 

materials such as ceramics, glass, and plastic. Used wet or dry, non-wovens enable the user to achieve a consistent, 

uniform finish, and conformability to irregular surfaces, with minimal smearing and discoloration of the workpiece.

Components of Non-Woven Abrasives

 While non-wovens are made in a different way than conventional coated abrasives, both types of products use many

of the same abrasive minerals. Silicon carbide is sharper, cuts faster, and produces finer scratch patterns on most 

surfaces. Aluminum oxide is more durable and tends to last longer. It is more aggressive on certain applications 

(such as hardened steel parts), and produces less discoloration on aluminum. When the non-woven supplier talks 

about grit, he is referring to the size of the abrasive grain impregnated into the nylon web. The lower the number, 

the larger the grains. The use of large particles (coarse grit) results in a more aggressive cut and a coarser finish. 

Small size particles result in a non-woven product that produces fine surface finish, if all other conditions are equal. 

In specifying a conventional bonded or coated abrasive product, the purchaser selects a specific grit size – say, 

120 grit. With non-woven abrasives, by comparison, one of the following designations is used: 

 

Grit Designation and Comparable Grit Ranges

Coarse (C) 50 – 80

Medium (M) 100 – 150

Fine (F) 180 – 220

Very Fine (VF) 240 – 360

Ultra Fine (UF) 600

Micro Fine (SF) 1000 – 1200
