PFERD 48311 3" x 1/2" Unitized Wheel 1/4" A.H., A/O Coarse (W) 8AM
PFERD offers a wide range of coated and non-woven abrasive tools for face-down grinding, belt grinding, peripheral grinding, surface conditioning, polishing, and much more.
POLINOX unitized wheels and discs consist of multiple heavily compressed, non-woven layers, which are bonded together by a special grain/resin system. This particular bond results in non-woven products with a very good surface finish, high stock removal rate and long service life.
These properties are particularly apparent when deburring, blending, finishing and polishing soft metals, alloyed and high-alloy steels, in addition to titanium alloys.
Type for straight grinders, flexible shafts and bench grinders: Ideal for work on smaller surfaces. Type for variable-speed angle grinders and fillet weld grinders: They are ideal for work on fillet welds and very hard-to-reach slots or indentations.Materials that can be worked:- Aluminium
