Pferd 39008570 Bench Grinding Wheel 150 x 20 mm, Silicon Carbide, Grit 60, 32 mm Bore

The Pferd CARBIDE bench grinding wheel is a silicon carbide (CN) wheel for mounting on a bench grinder. This page lists five items: three 150 x 20 mm wheels in grits 60, 80 and 120, and two 200 x 25 mm wheels in grits 80 and 120.

The catalogue describes the CARBIDE design as used on hard materials, for example for sharpening tungsten carbide tools and hardened steels (manufacturer-stated).

Features listed are long tool life, high dimensional stability, high abrasive performance and integrated adapter sleeves for mounting on almost any bench grinder spindle (manufacturer-stated).

The two 200 x 25 mm wheels differ in bore: grit 80 is listed with a 32 mm bore and grit 120 with a 51 mm bore.

Common specifications

Key specifications

Each item number is a separate size, bore and grit combination.

Selecting the right option

Match the bore and size to your bench grinder. A higher grit number is a finer abrasive. For safety reasons, never exceed the maximum rotational speed printed for the item. The catalogue gives the maximum permitted peripheral speed as 35 m/s, and says to ring test the wheel before clamping: an undamaged wheel gives a clear tone (manufacturer-stated). Dress the wheel regularly to expose sharp grain and keep an even grinding face, and keep the workpiece support adjusted to the wheel diameter with a gap of no more than 3 mm (manufacturer-stated).
