Traditional long drill bits often flex or wander, leading to misplaced pilot holes and splintered surfaces—especially in tight corners. Our Stubby Series is engineered for maximum rigidity and control. By reducing the overall length, we have eliminated bit "walking," ensuring high-concentricity boring in the most confined areas.
Forged from premium HSS 4241 (High-Speed Steel), this set provides industrial-grade performance for cabinetry, furniture making, and professional installations, delivering perfectly centered, clean-cut holes in all wood and plastic substrates.

Each bit is precision-ground from vacuum-tempered HSS and features a non-slip power hex shank. All bits in this set share a consistent, optimized stubby length for uniform depth control.
| No. | Specification (D) | Flute Length (L2) | Overall Length (L1) | Shank Type |
| 1 | 1/16" | 0.90" | 2.32" | 1/4" Hex Shank |
| 2 | 3/32" | 1.10" | 2.32" | 1/4" Hex Shank |
| 3 | 1/8" | 1.10" | 2.32" | 1/4" Hex Shank |
| 4 | 3/16" | 1.10" | 2.32" | 1/4" Hex Shank |
| 5 | 1/4" | 1.18" | 2.32" | 1/4" Hex Shank |
| 6 | 5/16" | 1.18" | 2.32" | 1/4" Hex Shank |
| 7 | 3/8" | 1.18" | 2.32" | 1/4" Hex Shank |
The uniform 2.32-inch length minimizes bit breakage and vibration common in thin-diameter bits (like 1/16" or 3/32"). It is the definitive choice for drilling inside drawer boxes, cabinetry face frames, or between joists where standard bits are too long to maneuver.
The sharpened center point acts as a pilot, ensuring the hole starts exactly where you marked it. It eliminates "skating" on polished wood or laminated surfaces, which is critical when drilling pilot holes for hinges or decorative hardware.
Forged from premium HSS 4241 (High-Speed Steel), these bits stay sharp longer than carbon steel bits when drilling dense hardwoods or composites. The deep, polished flutes facilitate rapid chip evacuation, preventing friction heat and burn marks on the wood.
Designed for modern high-torque impact drivers, the universal hex shank provides a positive lock in all professional drill chucks and quick-release bit holders, preventing slippage.

Q1: Why choose "Stubby" bits over standard bits?
A1: "Stubby" bits provide significantly greater stiffness and strength, preventing bit flex and breakage, especially in small diameters. They are also essential for drilling inside confined spaces where a standard-length bit cannot maneuver.
Q2: Can I use these bits on metal?
A2: No. While they are made of HSS, the delicate Brad Point and Double Spur geometry are specifically ground for wood and plastics. Using them on metal will immediately damage the precision tips.
Q3: Are these compatible with impact drivers?
A3: Yes. The 1/4" (6.35mm) hex shank is a universal power-groove design, suitable for all quick-change chucks and impact drivers.
Q4: Do these bits produce clean through-holes in delicate veneers?
A4: Absolutely. The outer spurs score the wood fibers around the circumference before the main cutting edge engages, producing a smooth entrance and exit, which is essential for preserving high-value veneers and laminated surfaces.
