The Fractional Drill – Jobber Length (011411) is engineered for professionals who demand precision, durability, and consistent performance across a wide range of metalworking, woodworking, and maintenance tasks. Designed with a job‑length shank for optimal torque transfer, this drill delivers clean, accurate holes in steel, stainless steel, aluminum, brass, and many non‑ferrous alloys.
Key Features & Benefits
- High‑Speed Steel (HSS) Construction: Offers superior wear resistance and maintains sharpness even after prolonged use.
- Jobber Length Shank (0.250” – 0.500”): Provides the perfect balance between rigidity and flexibility for deep‑hole drilling.
- Fractional Size Range: Available in 1/64” increments for exact sizing and interchangeable use across multiple toolsets.
- Precision Ground Tip: Ensures concentric holes and reduces chatter, resulting in smoother finishes.
- Coated Finish: TiN or black oxide coating options increase heat resistance and extend tool life.
- Universal Compatibility: Fits standard drill presses, magnetic drills, CNC machines, and handheld power drills.
