Fractional Drills – Jobber Length (011406)
Discover the ultimate in precision machining with our Fractional Drills – Jobber Length (part number 011406, UPC 086839114064). Engineered for professional metalworkers, machinists, and hobbyists, these high‑performance drills deliver consistent, clean holes in a wide range of materials—from hardened steel to aluminum and plastics. Whether you’re outfitting a production line or a personal workshop, our jobber‑length fractional drills provide the reliability and accuracy you demand.
Key Benefits of Our Jobber Length Fractional Drills
- Superior Accuracy: Ground to exacting tolerances for true-to-size holes every time.
- Durable Construction: High‑speed steel (HSS) with a titanium nitride (TiN) coating resists wear and heat buildup.
- Versatile Jobber Length: Optimized shank length for deep drilling while maintaining rigidity.
- Fractional Sizing: Precise fractional increments (¼”, ⅜”, ½”, etc.) for fine‑tuned adjustments.
- Enhanced Chip Evacuation: Deep flutes and a sharp point geometry reduce clogging.
- Compatibility: Fits standard 3/8” and 1/2” collet chucks, as well as keyless drill presses.
Product Overview
The 011406 Fractional Drill is crafted from premium high‑speed steel, providing an ideal balance of toughness and heat resistance. Each drill is meticulously ground and then coated with a thin layer of titanium nitride to extend tool life by up to 30 % compared with conventional HSS drills. The jobber‑length shank (typically 2‑3 inches) offers the perfect blend of reach and stiffness, making it ideal for deep‑hole applications without sacrificing control.

Tips for Optimal Performance
- Secure the workpiece: Use a stable vise or clamp to prevent vibration.
- Use proper feed rates: Adjust feed pressure according to material hardness to avoid dulling.
- Coolant application: Apply cutting fluid or mist for deep holes and hardened steels.
- Re‑sharpen when needed: While TiN extends life, periodic sharpening restores peak performance.
- Inspect the coating: Replace any drill showing coating wear to maintain tool longevity.
