"Hex Shank" Premium Steel Forstner Bits
- Reviews
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. ♥ indicates bit has a round shank.
Use the 1-3/8 (35mm) forstner bit (item #9219) to mount 35mm European cup hinges, and the 2-1/8" fortner bit (#9231) to mount door locks.
Use the 3-1/8" forstner bit (item #9247) to mount clock movements.

I bought one bit to try it out and was impressed with how well it cut for the price. The grinding is rough but a few passes with a diamond file and it is ready to go. I typically use a keyless chuck on my wood lathe and getting the larger bits not to spin is difficult if not impossible. The hex shank solves that problem. Yesterday I ordered the 16 piece set and am looking forward to replacing my round shank bits with these.

Recently bought the 9/16" forstner bit. This bit is basically unusable for my application. I am drilling into exotic woods like purpleheart, wenge and bocote, and I can't clear the bit enough to keep it from loading up. One touch of the wood and the bit is packed and I have to stop the drill and clear the bit by hand. Won't buy again.

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.
