Square Edge Felt Wheels: 100% wool felt The felt wheels offer a unique, cushioned fine buffing and polishing action. That isn’t coated abrasive belt, cotton buffing wheel, or any other fabricated or natural product can duplicate. The felt wheels are used either with or without polishing compounds depending upon the material to be processed and the finish desired. According to the wool density, we supply 5 kinds of hardness felt wheels. Soft, medium, hard, rock hard and flint hard. The density details for our felt wheels are as bellow: Soft: 0.40g/cm³ Medium: 0.45g/cm³ Hard: 0.50g/cm³ Rock Hard: 0.65g/cm³ Flint hard: 0.80g/cm³ Soft felt wheels are generally used for rounded surfaces and special applications requiring minimal pressure and cutting action. This density is used for polishing glass, granite and marble. Medium felt wheels are recommended for most industrial work and readily adapt to either flat or rounded surfaces. They are often used in polishing and buffing operations with polishing compounds and lubricants. Medium felt wheels are recommended for polishing metals, jewellery, stone, woodwork and glass. Hard felt wheels are usually used on flat surfaces or in applications where it is necessary to contour the wheel to the configuration of the piece part. This is the density normally used by lapidarists and jewellery manufacturers. Hard felt wheels are usually used for jewellery, percussion instruments, dentistry, and glass polishing. Rock hard felt wheels are used in operations demanding maximum cutting pressure and where sharp edges or critical contours on the piece part require close tolerance or complex wheel shaping. Typical application areas include: Jewellery, windshield repair, plastic part lines, all metals, medical parts, fiberglass, stone, glass polishing, dental.
