Ordinary forstner bits are prone to premature dulling of the cutting edges unless they are used at very low speeds and kept sharp.
FAMAG Bormax bits have been designed specifically for powered use. The outer perimeter is relieved allowing the heat generated at the cutting edge to dissipate.
They can be used freehand or in a drill press.
The Bormax design works so well that they are cool enough to hold within a few seconds of being withdrawn from the hole, cooler running means the cutting edges remain sharp for longer and so the overall durability of the tool is greatly extended and maintenance reduced.
