The Diablo 1 in. High-Speed Steel Forstner Bit drills straight, angled and overlapping holes in all types of wood without splintering. It features a double-ground serrated edge for less splintering and chipping.
- Minimum chuck size of 3/8 in.
- Drills straight, angled and overlapping holes in all types of wood
- Forged construction of the hardened steel body warrants a long bit life and a sharper cutting edge
- Ultra-sharp center spur ensures an accurate hole without walking on material
- Steep, angled cutting edges produce smooth, flat holes and create chisel-like curls for fast, clean chip removal

Fast clean cuts, just remember to clamp a backer so the punch through doesn’t splinter soft woods in particular.

Wears quickly in oak. Was working on stair railings and after about 10 holes, started to burn and smoke. Went through 3 of these for 30 holes.

This Forstner bit is being used in fine woodworking and it does the job very well. I can’t think of any negatives with this bit.

It drilled well but not as well as I had expected.
Billie O’Hara (verified owner) –
cuts extremely hard wood (3000+ janka hardness) with ease does leave a tiny dot in the center, but that’s to be expected.

Excellent product, well made, very sharp. I used the bit to countersink/recess bolt heads and flat washers into wooden posts for a home project a week ago. The bit cut cleanly and easily via my moderate size drill press. The bit met my expectations. I recommend this product.

Had to put a transducer on my boat. Drill through 3/8 to 1/2 inch of fiberglass. Did it very cleanly.

I used the bit to mortise hinges on new wood shutters I installed, a technique I learned about on http://www.thisoldhouse.com The bit was steady, and cut neatly and cleanly, making the job much quicker.

Very sturdy. Works well if you have a sturdy drill to use it with. Would definitely recommend considering the near perfect holes it created.

I needed a 1 inch Forstner Bit for a project that I was building for my Grandkids. It worked perfectly on the oak 1X3’s I was using. It is very sharp and drilled the holes with no problems. I highly recommend the Diablo product as it far exceeded my expectations.
