The Diablo 1-7/8" Forstner Bit for Wood is a high-speed steel boring tool engineered for woodworkers who need clean, flat-bottomed holes in hardwoods, softwoods, veneered plywood, and MDF. Designed for use in both a drill press and a hand held drill, this 1-7/8" bit delivers precise, splinter-free results whether you are drilling straight holes, angled bores, or overlapping cuts. Its double-ground serrated edge minimizes chipping at the entry point, making it a reliable choice for finish woodworking, cabinet making, joinery, and general carpentry projects that demand accuracy and clean results.

Key Features

• Double-ground serrated edge - reduces splintering and chipping as the bit enters the wood, preserving the surface quality of hardwoods, softwoods, and veneered plywood
• Forged hardened steel body construction - warrants a long bit life and a sharp cutting edge, meaning fewer replacements and consistent performance over extended use
• Ultra-sharp spur point - guarantees an accurate hole without walking on the material, so you hit your mark precisely every time without the bit drifting or tearing the grain
• Drills straight, angled, and overlapping holes - gives woodworkers the flexibility to tackle a wide range of joint and pocket-hole configurations with a single bit
• Compatible with drill press and hand held drill - versatile tool compatibility means you can use this bit in a controlled bench setting or out in the field with a portable drill
• Requires a minimum chuck size of 3/8" - fits standard 3/8" and larger chucks, making it compatible with a wide range of common woodworking drills

Why This Product

• When drilling flat-bottomed holes, pocket holes, or overlapping bores in finish wood, the double-ground serrated edge keeps edges clean and chip-free - critical for cabinetry, furniture, and veneered surfaces where tearout is unacceptable.
• The forged hardened steel body is built to stay sharp through repeated use in dense hardwoods and abrasive MDF, reducing the frustration of dull bits that slow production or leave rough hole walls.
• The ultra-sharp center spur locks onto the drill point immediately, eliminating bit walk on smooth or sloped wood surfaces - a key advantage when precision placement matters.
• At 1-7/8" diameter and 3-1/2" total length with a 3/8" shank, this bit opens large, accurate bores suited for hinge mortising, shelf pin holes at scale, and overlapping hole patterns without requiring a specialty drill or adapter.

Frequently Asked Questions

What materials can the Diablo 1-7/8" Forstner Bit drill through?

This bit is designed to drill through hardwoods, softwoods, veneered plywood, and MDF. Its double-ground serrated edge is specifically engineered to minimize splintering and chipping across all of these wood types.

What is the minimum chuck size required to use this Forstner bit?

The Diablo FB-014 has a 3/8" shank and requires a minimum chuck size of 3/8". It is compatible with both drill press chucks and hand held drill chucks that meet this minimum size requirement.

Can this bit be used to drill angled or overlapping holes, or only straight bores?

Yes - this bit is capable of drilling straight holes, angled holes, and overlapping holes in all types of wood. That flexibility makes it well suited for joinery, hinge mortising, and multi-hole patterns in woodworking projects.

What makes the Diablo Forstner bit stay accurate without drifting on the workpiece?

The bit features an ultra-sharp spur that seats into the wood surface at the start of the bore, preventing the bit from walking or drifting off the intended drill point. Combined with the forged hardened steel body, this design supports consistent accuracy and a long, sharp cutting edge over repeated use.
