3M 33229, Scotch-Brite SF Finishing and Deburring Wheel, SF-WL, 11S Fine, 6 in x 1 in x 1 in, 7000121078

Convolute Construction
To construct our Scotch-Brite™ SF Finishing and Deburring Wheel we wrap non-woven abrasive web around a fiberglass core. With convolute wheels the surface of the web becomes the cutting tool. Moreover, the wheels are one directional, which is indicated by an arrow on the side of the wheel and arrows printed on the core. Following the direction indicated on the wheel is imperative — both for optimal wheel performance and operator safety. Considering all variations of Scotch-Brite™ convolute wheels, the SF wheel falls in the middle in terms of aggressiveness and durability. When compared to other Scotch-Brite™ materials, it could be considered medium-density. Yet, this is one of the characteristics that makes it perfect for balancing deburring with finishing. It is aggressive enough to tackle flash and imperfections, while soft enough to not severely gouge the part.

Key Ingredients: Silicon Carbide, Resin and Nylon
The abrasive material in the Scotch-Brite™ SF Finishing and Deburring Wheel is a combination of non-woven nylon fibers and silicon carbide mineral. To combine these elements, we use a resin bond. The resin bond breaks down gradually while the wheel wears, helping with overall heat resistance. It is an excellent option when finish is critical on deburring applications. Silicon carbide mineral is very hard and fractures easily, resulting in freshly exposed sharp edges that cut extra fast and produce a smooth, professional-looking finish. While it wears faster than aluminum oxide, it produces a superior finish.

Key Strike a Balance
Some common applications include general deburring of machined and formed parts, deburring and finishing turbine blades, gun barrel polishing, golf club finishing and medical component deburring and finishing. Altogether, this wheel is uniquely equipped to help operators remove flash and imperfections while achieving a refined and polished finish.
