Bench Grinder / Polisher with Flexible Drive

A compact and versatile mini bench grinder for model makers.

This is really a multi-purpose tool capable of carrying out grinding, polishing & sanding operations on small components.

One side is fitted with a grey grinding stone for sharpening (chisels, drill bits and tools), reshaping, deburring etc.

The other side is fitted with a soft polishing wheel, able to polish and smooth all kinds of materials, such as precious metals, non-ferrous metals, stainless steel, glass, porcelain, wood, rubber and plastic. Some materials will require a suitable polishing compound to be used. 

To add another level of versatility, we also include a power take off to fit a flexible rotary shaft. The rotary shaft has a 3.2mm collet chuck (compatible with Dremel type tools) and we include a 100 piece accessory kit enabling a wide variety of applications such as engraving, carving, routing, cutting, sanding & polishing.

The grinder sits on 4 rubber feet to provide a stable platform. It can also be secured to a work bench using the 4 mounting points provided.

Supplied with spark guards, eye shields, tool rests, rotary shaft, 100 piece accessory kit, 1.75m cable and UK 3 pin plug.
