KF Wheel for Flexible Sander
< Characteristics >
This product is specially designed for flexible sander. The number of flaps are increased by 30% compared to KF Wheels, and the length of abrasive cloth (flaps) are also changed to prevent bounds during polishing. Due to these changes, more cutting power with less loading can be achieved.

* Outer diameter of a brand-new KF Wheel seems to be a little smaller than its actual size since the fins rise by centrifugal force during use.
* Please specify the details as bore size when you order flange built-in type.
e.g. O.D. 200 x Width 25 x I.D. 65 × Bore 25.4
* Please specify the details as I.D. size when you order flange separated type.
e.g. O.D. 350 x Width 75 x I.D. 130
* Please ask us about wheels wider than 100mm or special combination of O.D. and I.D. not marked "" in the table on the left. Also, we have special type of wheels "SL- type(with slit)" and "SSL-type(with spiral slit)
