Product Description
The Diablo 1 3/8" Forstner Bit for Wood is a precision-engineered drilling tool designed for woodworkers who demand clean, flat-bottomed holes in hardwoods, softwoods, veneered plywood, and MDF. Built with a forged hardened steel body and an ultra-sharp center spur, this bit delivers accurate, splinter-free results whether you are drilling straight through, at an angle, or creating overlapping holes. Compatible with both a drill press and a hand-held drill, it is a versatile addition to any wood shop or jobsite toolkit.
Key Features
- Drills straight, angled, and overlapping holes in all types of wood without splintering - meaning cleaner results in finish carpentry, cabinetry, and joinery work where surface quality matters
- Forged construction of the hardened steel body warrants a long bit life and a sharp cutting edge - so you spend less time replacing bits and more time working
- Ultra-sharp spur guarantees an accurate hole without walking on the material - giving you precise hole placement even on smooth or slippery wood surfaces
- Steep, angled cutting edges produce smooth, flat holes and create chisel-like curls for fast, clean chip removal - reducing heat buildup and keeping your cut clear for faster, more efficient drilling
- Requires a minimum chuck size of 3/8" - compatible with most standard hand-held drills and drill presses already found in the workshop
- 1 3/8" diameter with a 3-1/2" overall length - sized for drilling wider flat-bottom holes, pocket holes, and overlapping bores in a variety of wood types
Why This Product
- If you need flat-bottom holes for shelf pin drilling, hinge mortising, or pocket joinery, the steep angled cutting geometry of this Forstner bit produces smooth, level hole bottoms that paddle and spade bits simply cannot match.
- The forged hardened steel body is built to outlast lesser bits through repeated use across dense hardwoods and abrasive materials like MDF - making this a durable, long-term investment for serious woodworkers.
- At 1 3/8" in diameter, this bit fills a common size needed for knob and pull boring, dowel work, and overlapping hole patterns in cabinet construction and furniture making.
- The center spur eliminates wandering at the start of the cut, so even freehand drilling with a hand-held drill produces accurately placed holes - no pilot hole or center punch needed.

Frequently Asked Questions
What materials can the Diablo FB-010 Forstner Bit cut through?
This bit is designed to drill through hardwoods, softwoods, veneered plywood, and MDF. It is not intended for use on metal, masonry, or non-wood materials.
What is the minimum chuck size required to use this Forstner bit?
The Diablo FB-010 requires a minimum chuck size of 3/8". Its 3/8" shank is compatible with most standard hand-held drills and drill presses that accept that chuck size or larger.
Can this bit be used to drill angled or overlapping holes, or only straight through holes?
Yes - this Forstner bit is specifically designed to drill straight, angled, and overlapping holes in all types of wood without splintering, making it highly versatile for complex joinery and cabinetry applications.
What type of holes does a Forstner bit produce compared to a standard twist or spade bit?
Forstner bits like the Diablo FB-010 produce flat-bottomed holes with smooth sidewalls, which is ideal for shelf pin drilling, hinge mortising, and pocket hole work. The steep angled cutting edges create chisel-like curls for fast chip removal, resulting in cleaner holes than most spade or twist bits produce in wood.
