The Diablo 1-1/4" Forstner Bit for Wood is a precision-engineered boring tool built for woodworkers who need clean, flat-bottomed holes in a wide range of wood materials. Crafted from high-speed steel with a forged, hardened steel body, this bit delivers the durability and sharpness needed for straight holes, angled entry cuts, and overlapping hole patterns in hardwoods, softwoods, veneered plywood, and MDF. Whether you are working at a drill press or using a handheld drill, this Diablo Forstner bit is designed to produce smooth, splinter-free results with every pass.

Key Features

• High-speed steel construction with a forged, hardened steel body - extends bit life and maintains a sharper cutting edge through repeated use in demanding wood-boring applications
• Double-ground serrated cutting edge - reduces splintering and chipping at the hole perimeter, producing cleaner results in veneered plywood and finished wood surfaces
• Ultra-sharp center spur - anchors the bit on contact and prevents walking, so your hole placement stays accurate even when drilling at an angle or near an edge
• Steep, angled cutting edges - shear material in chisel-like curls for fast chip removal, which keeps the bit running cooler and leaves a smooth, flat hole bottom
• Drills straight, angled, and overlapping holes - gives you versatility for pocket holes, through-holes, and side-by-side boring patterns without switching tools
• 3/8" shank with a minimum 3/8" chuck requirement - fits standard drill presses and handheld drills commonly found in woodworking shops
• 1-1/4" diameter at 3-1/2" overall length - sized for shelf pin holes, dowel pockets, and other common furniture and cabinetry boring tasks

Why This Product

• Forged steel body construction means the bit holds its edge longer than lesser-quality alternatives, reducing the frequency of sharpening or replacement during high-volume wood drilling projects
• The double-ground serrated edge specifically addresses splintering and chipping - a common frustration when boring veneered plywood or fine hardwoods - so finished surfaces stay presentable without extra sanding
• Compatible with both a drill press and a handheld drill, this bit adapts to the tool you already own rather than requiring specialized equipment
• Capable of drilling overlapping holes as well as angled entries, this 1-1/4" Forstner bit handles tasks beyond simple straight boring, making it a practical choice for joinery, hardware installation, and custom cabinetry work

Frequently Asked Questions

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

This bit requires a minimum chuck size of 3/8". It has a 3/8" shank, so it is compatible with any drill press or handheld drill that accepts a 3/8" or larger chuck.

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

Yes - this Diablo Forstner bit is specifically designed to drill straight, angled, and overlapping holes in all types of wood, making it suitable for a wider range of joinery and boring techniques than a standard twist bit.

What wood materials is this bit rated to work with?

This bit is designed for use in hardwoods, softwoods, veneered plywood, and MDF. The double-ground serrated edge helps minimize splintering and chipping across all of these material types.

What does the forged steel body construction offer compared to a standard bit body?

The forged construction of the hardened steel body provides greater structural integrity, which supports a longer bit life and helps maintain a sharper cutting edge through repeated use compared to non-forged alternatives.
