Diablo FB-016 2-1/8 Inch High Speed Steel Forstner Drill Bit 3/8 Shank Serrated Edge for Straight Angled and Overlapping Wood Holes

Precision Boring for Custom Joinery: Diablo 2-1/8 Inch High Speed Steel Forstner Bit

Elevate your woodworking projects with the Diablo FB-016 2-1/8" High-Speed Steel Forstner Bit, the ultimate tool for drilling large, clean, and dimensionally accurate holes. Unlike standard auger or spade bits that tear through material, this precision cutter creates smooth, flat-bottomed holes with minimal splintering. It is specifically engineered with a double-ground serrated edge that slices through wood fibers cleanly, making it perfect for installing hidden hardware, creating mortises, or drilling overlapping holes for decorative effects in both hardwoods and softwoods.

Built for endurance and consistent performance, Diablo utilizes a premium forged high-speed steel construction rather than the casting process used by competitors. This results in a stronger, more durable bit that maintains a razor-sharp edge even under high heat. The ultra-sharp center spur ensures pinpoint accuracy, preventing the bit from "walking" across the surface when starting a cut. With its steep, angled cutting geometry, this bit produces chisel-like curls that clear chips rapidly, keeping the bit cool and extending its lifespan. It features a standard 3/8-inch round shank, making it compatible with most drill presses and portable drills.

Key Features

• Serrated Edge Technology: Double-ground serrated rim slices efficiently throughout rotation for virtually splinter-free holes.
• Forged Strength: Manufactured from forged high-speed steel for superior durability and longer edge retention compared to cast bits.
• Precision Centering: Ultra-sharp center spur locates the hole center accurately and resists walking on the material.
• Versatile Drilling: Capable of drilling straight, angled, and overlapping holes (flat bottom) in all wood types.
• Efficient Chip Removal: Steep angled cutting edges generate large shavings to evacuate debris and reduce heat buildup.
• Universal Compatibility: 3/8-inch round shank fits securely in standard drill chucks and drill presses.

Specifications

Pro-Tip: A 2-1/8" bit creates significant surface contact and torque. For the cleanest results and to prevent burning the wood, use a drill press set to a low speed (under 500 RPM). If using a hand drill, maintain a firm two-handed grip to counter the rotation and withdraw the bit frequently to clear the large chips.
