Product Description
The Diablo Forstner Bit Set for Wood (7-piece) gives woodworkers a complete starter collection of high-speed steel Forstner bits engineered to drill straight, angled, and overlapping flat-bottom holes in a wide range of wood materials - from dense hardwoods and softwoods to veneered plywood and MDF. Covering sizes from 1/4 in. to 1 in. diameter, this 7-piece set is built with a forged, hardened steel body and a double-ground serrated cutting edge that resists splintering and chipping for cleaner results in every boring application. Whether you are working at a drill press or using a hand held drill, these bits deliver accurate, professional-quality holes.
Key Features
- High-speed steel construction with a hardened steel body - provides a longer cutting life and maintains a sharper edge through repeated use in hardwoods, softwoods, veneered plywood, and MDF
- Double-ground serrated cutting edge - reduces splintering and chipping so hole walls stay clean and smooth, minimizing finishing work
- Steep, angled cutting edges produce smooth, flat holes and create chisel-like curls - allows fast, clean chip removal that keeps the work surface clear and prevents bit overheating
- Ultra-sharp spur tip - guarantees accurate hole placement without walking on the material, so every hole starts exactly where you mark it
- Compatible with drill presses and hand held drills - gives you flexibility to use the same set in both shop and jobsite environments
- Set contains the 7 smallest sizes in Diablo's Forstner bit lineup, ranging from 1/4 in. to 1 in. diameter - a single purchase covers the most commonly needed boring sizes for pocket holes, flat-bottom holes, and overlapping holes
- Requires a minimum chuck size of 3/8 in. - ensures compatibility is confirmed before setup, preventing tool mismatches on the job
Why This Product
- One set covers the most-used Forstner bit diameters (1/4 in. through 1 in.) so woodworkers can tackle pocket holes, hinge mortises, flat-bottom bores, and overlapping hole patterns without purchasing individual bits separately.
- Forged, hardened steel body construction means these bits hold their edge longer than standard tooling, reducing replacement frequency and downtime during woodworking projects in hardwoods and softwoods alike.
- The double-ground serrated edge design actively fights splintering and chipping - critical when drilling veneered plywood or MDF where surface damage around the hole is a common concern with lesser bits.
- Precision-ground ultra-sharp spur prevents bit walking at the start of each hole, delivering repeatable accuracy whether you are boring at the drill press or freehand with a hand held drill.

Frequently Asked Questions
What diameter sizes are included in the Diablo FB-107 Forstner bit set?
The FB-107 set includes 7 Forstner bits spanning diameters from 1/4 in. to 1 in. - specifically the 7 smallest sizes in Diablo's Forstner bit lineup. This range covers the most commonly used boring sizes for pocket holes, flat-bottom holes, and overlapping hole applications.
What is the minimum chuck size required to use these bits?
These Forstner bits require a minimum chuck size of 3/8 in. The shank sizes in the set range from 1/4 in. to 3/8 in., so confirming your drill press or hand held drill meets this minimum chuck requirement before use is recommended.
What types of wood and wood products can these Forstner bits drill?
The Diablo FB-107 set is designed to drill hardwoods, softwoods, veneered plywood, and MDF. The double-ground serrated cutting edge is specifically engineered to minimize splintering and chipping - making it well suited for surface-sensitive materials like veneered plywood and MDF where a clean hole perimeter is important.
Can these bits be used with a hand held drill, or are they limited to a drill press?
These bits are compatible with both drill presses and hand held drills. The ultra-sharp spur tip helps prevent the bit from walking on the material surface, which is especially useful when starting holes freehand with a hand held drill rather than a fixed drill press setup.
