Our new product Kuzmin™ HSSF Brush (High Speed Super Finish Brush with extremely thin polybutylene terephthalate bristles) is a member of a next generation of ski roto-brushes. The habitual roto-brush is designed to be attached to electric drill by chuck. Usually such solution cannot provide more than 2900 rpm and accompanied by significant eccentric oscillation.
The Kuzmin™ HSSF Brush is designed to be attached to angle grinder (a handheld power tool). To any angle most common grinder with a M14 spindle. The solution provides up to 12000 rpm and practically total lack of eccentric oscillation. The brush’s bristles are made of high quality extremely thin (0.08 mm stem, 0.01 – 0.02 mm tip) polybutylene terephthalate filament.

Therefore, this combination - high rotational speed and soft, extreme thin bristles polish all the valleys inside the ski base structure, even inside the very fine structure. And shining well polished (finished) structure is a prerequisite for a good glide on the cold dry snow.

Please, pay attention! The revolving brush has to be kept in constant lengthwise motion. Motion can be very slow; it can be back-and-forth motion. But it has to be motion. Never stop.
Do not push the brush against ski base. The pressure has to be very light.

Though we do not recommend to glide wax skis, we have to point out, that Kuzmin™ HSSF Brush works very well even on glide waxed (hot waxed) skis.
