Key Features
Overview
The Diablo FB-001 1/4 Inch Forstner Bit is a single high-speed steel wood-boring bit built for clean, flat-bottom holes in wood. This is a Forstner bit designed for drilling accurate straight, angled, and overlapping holes in wood. Model Number: FB-001. If you need a small-diameter hole that starts cleanly and stays controlled, this bit is built for that kind of work.
What matters here is cut quality. Diablo uses an ultra-sharp spur to help the bit start accurately without walking across the material. On the job, that means less wandering at the start of the cut, better placement on finished surfaces, and cleaner results when you're working in hardwood, softwood, plywood, MDF, particle board, laminate, or veneered panels.
The cutting geometry is aimed at the kind of finish people expect from a proper Forstner bit, not a rough boring bit. The steep angled cutting edges are made to produce smooth, flat holes while clearing chips efficiently. That makes a difference when you're drilling shallow recesses, hardware holes, or overlapping cuts where a standard twist bit would leave a rougher result and a spade bit would be too crude.
Diablo also backs up the cutting edge with a hardened high-speed steel body and forged construction. That combination matters because small bits still take abuse, especially when they're used repeatedly in dense wood or sheet goods. A stronger body helps the bit hold up longer, while the sharper edge helps reduce extra pressure that can scorch material or leave a ragged rim.
At 1/4 inch diameter with a 1/4 inch shank and 3-1/2 inch overall length, this bit fits a wide range of drilling setups without being oversized for detail work. Diablo calls for a minimum chuck size of 1/4 inch, and the bit is suited for use in either a hand-held drill or a drill press. That gives you flexibility whether you're drilling on-site, working at the bench, or setting up repeatable holes in a shop environment.
This is a good fit for woodworkers, finish carpenters, cabinet installers, remodelers, and serious DIY users who need a small, accurate wood-boring accessory instead of a general-purpose drill bit. If your work involves clean holes in visible material, hinge work, overlapping cuts, or controlled boring in sheet goods, this bit makes more sense than forcing a standard bit to do a precision job it was never made for.

Pro Tip
For the cleanest entry in veneered plywood or laminate, let the spur establish the cut before adding heavy pressure. This bit is designed to resist walking, so a steady start usually gives you a cleaner rim than forcing it right away.
