FAMAG 1622 Bormax Forstner bits have been designed specifically for powered use. The outer perimeter is relieved allowing the heat generated at the cutting edge to dissipate. FAMAG 1622 Forstner bits can be used freehand or in a drill press, the larger ones at up to 750rpm, the smaller ones at up to 2500rpm.
The Bormax design works so well that they are cool enough to hold within a few seconds of being withdrawn from the hole, the cutting edges remain sharper for longer and so the overall durability of the tool is greatly extended and maintenance reduced.
As with all FAMAG products they are manufactured to exacting tolerances, so hole drilled with a FAMAG bit will always precisely match a plug cut with a corresponding FAMAG plug cutter.
