The Pferd UNIVERSAL bench grinding wheel is a regular aluminium oxide (AN) wheel for mounting on a bench grinder. This page lists six items: three 150 x 20 mm wheels and three 200 x 25 mm wheels, each size in grits 24, 36 and 60.

The catalogue describes the UNIVERSAL version as made for universal use in the workshop on steel, cast steel, stainless steel (INOX) and cast iron (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 200 x 25 mm wheels differ in bore: two are listed with a 51 mm bore and one with a 32 mm bore, so check the bore column in the table before you order.

Common specifications

Key specifications

Each item number is a separate size and grit combination. The maximum speed depends on the wheel diameter.

Selecting the right option

Match the bore and size to your bench grinder, and choose the grit for the job: 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).
