UPC: 086839114163
Overview
Discover the reliability and precision of our Fractional Drills – Jobber Length (model 011416). Engineered for professional machinists, maintenance technicians, and serious hobbyists, these high‑quality drill bits deliver consistent performance across a wide range of materials. Whether you’re drilling steel, stainless steel, aluminum, brass, or cast iron, these fractional‑size drill bits provide the perfect blend of durability, accuracy, and speed.
Key Features & Benefits
- Jobber Length Design: Optimized shank length for deeper cuts and increased chip evacuation, reducing heat buildup and extending tool life.
- Fractional Sizing: Precise fractional diameters (e.g., 1/8", 3/16", 1/4") for exact fit in engineering drawings, CNC programming, and repair work.
- High-Speed Steel (HSS) Construction: Hardened HSS tip for superior wear resistance and longer service intervals.
- Coated Finish: Advanced TiN or TiAlN coating (depending on batch) for reduced friction, lower torque, and improved surface finish.
- Balanced Geometry: Optimized point angle and web thickness for reduced wobble, smoother entry, and cleaner holes.
- Versatile Application: Ideal for drilling holes in metal fabrication, automotive repair, aerospace components, and general workshop projects.
- Secure Grip: Precision‑machined straight shank ensures a tight fit in standard drill chucks, minimizing run‑out.

Why Choose Fractional Jobber Length Drills?
When precision matters, the Fractional Drills – Jobber Length stand out for their consistency and resilience. The extended jobber length reduces the need for frequent bit changes during deep drilling, saving time and improving workflow efficiency. Their fractional sizing matches engineering specifications, eliminating the guesswork often associated with metric conversions.
Recommended Applications
- Automotive engine block drilling
- Aerospace component prototyping
- Industrial equipment repair
- Metal fabrication and welding preparation
- Precision CNC machining where exact hole dimensions are critical
Installation & Usage Tips
- Secure the drill bit in a high‑quality chuck to avoid slippage.
- Start at low RPM for initial penetration, then increase speed for clean exit.
- Use cutting fluid or lubricant when drilling hardened steel to reduce heat.
- Periodically check the drill tip for wear; replace when the cutting edge dulls.
- Maintain proper alignment to prevent chatter and ensure straight holes.
