I’m not sure how many times the Forstner bit can be reinvented, but let’s try at least one more time. Touting several improvements over other Forstner bits, the Maxicut Forstner bits made by Horst Miebach in Germany are sold under the Colt Brand.

The bits have a Rockwell hardness of 63 so they’ll stay sharp longer, but the side cutters can be resharpened when they do become dull. They work in cross grain and end grain and will drill straight, angled, or overlapping holes. Colt’s RotoStop shank system locks into any chuck or morse taper (with an adapter) and supposedly stops the shank from slipping and getting damaged.

All the bits have a self-cutting center point, and bits larger than 3/4″ have asymmetrical chip breakers to break up chips into ribbon like shavings which get ejected and don’t clog the bit. This configuration generates less heat and you can drill deep bores faster because you don’t have to back it out to clear chips as much as other Forstner bits.

The bits are sold in sizes ranging from 1/2″ to 2-1/4″. You’ll pay $25 to $48 a bit, depending on the size, or you can buy a 5- or 10-piece set for $140 or $270 respectively.

    Pricey, but I’m thinking about it. I’ve had large forstners spin in both my dp and my lathe when drilling deep holes in endgrain hardwood.

    I would be inclined to buy Bormax bits. One link here: http://www.alfatools.com/bormax.htm . Everything I have read about them suggests they are excellent. You can find them on the web.

    I have a set of these Maxicut forstner bits and am getting rid of my other forstner bits. There is no comparison. They cut at least 5 times faster, require less pressure to cut, heat up minimally and are a pleasure to use. Use in a battery powered hand drill works great. You will never be sorry you got them.
