"Individual" Forstner Bits
With self-spacing edge guides!
Forstner bits are designed to drill flat bottom or through holes cleanly in end grain, thin stock, veneers and regular stock. They enlarge existing holes with ease and can bore any arc of a circle. These bits will not move off center through unusual grain or knots. Great for mounting mini-quartz clock movements, cup hinges, and door locks. Sizes 1/4" to 7/8" bits are supplied with solid rims. The saw teeth design for larger diameter bits (1" and larger) stop burning and cut faster without losing the advantages of Forstner bit action. Shank size is 3/8" and overall length is 3-1/2" for sizes 1/4" through 2-1/8", excluding metric sizes. For sizes 2-1/4" through 4" shank size is 1/2" and overall length is 6-3/8". Use large bits in drill press.
Use the 1-3/8 (35mm) bit (item #9219) to mount 35mm European cup hinges, and the 2-1/8" bit (#9231) to mount door locks.
Use the 3-1/8" bit (item #9247) to mount clock movements.

I got a 3" bit, and it cuts a pretty nice hole for the money. I initially chucked it straight into my hand drill for boring out a hole in a stump, and it worked really well. The mass of metal did a good job of preventing a lot of heat buildup. When I got too deep, I had to get out my 7/16" extension, which is why I'm giving the bit a 4 out of 5.
The hex shaft on my bit was about 1/32 too large and I had to grind it down before it would fit properly. If I hadn't been at my shop, I wouldn't have been able to continue at all.
