The Fractional Drills – Jobber Length 011415 are engineered for professionals who demand the highest level of precision and durability in every hole they cut. Designed with a 0.125" (1/8") fractional shank and a classic job‑length profile, these drills deliver consistent performance across a wide range of materials—from soft aluminum to hardened steel.
Key Features & Benefits
- Superior Cutting Geometry: Optimized point angle and helix design reduce chatter and provide smoother entry, minimizing the risk of work‑piece deformation.
- Premium Material Construction: Made from high‑speed steel (HSS) with a titanium nitride (TiN) coating for increased hardness, heat resistance, and extended tool life.
- Jobber Length for Versatility: The 3‑inch (75 mm) jobber length offers the perfect balance between rigidity and reach, making it ideal for deep‑hole drilling and CNC spindle use.
- Fractional Shank Compatibility: The 0.125" (1/8") shank fits standard drill chucks, collets, and quick‑change tool holders, ensuring seamless integration into existing setups.
- Corrosion‑Resistant Finish: TiN coating provides a bright gold appearance while protecting the bit from rust and wear, even in demanding shop environments.
- Precision Ground Tip: The ground tip delivers a sharp, accurate point that reduces pilot drilling time and improves hole centering.

Why Choose the 011415 Fractional Drill?
When precision matters, you need a drill bit that can keep up. The 011415 fractional drill offers:
- Consistent hole tolerance (<±0.001") for fine‑fit assemblies.
- Reduced heat buildup thanks to the TiN coating, extending tool life by up to 30% compared with standard HSS bits.
- Ease of chip evacuation, preventing clogging during deep drilling operations.
- Compatibility with both manual drill presses and CNC machines, making it a versatile addition to any workshop.
Ideal Applications
The 011415 fractional drill is perfect for:
- Metal fabrication – drilling holes in steel, stainless steel, brass, and copper.
- Woodworking – creating precise pilot holes for dowels, screws, and hardware.
- Aerospace & automotive – high‑precision component drilling where tolerances are critical.
- Electrical & plumbing – clean, round holes for conduit and pipe fittings.
- CNC machining – programmed drilling cycles that require reliable repeatability.
Installation & Safety Tips
Installation: Secure the 0.125" shank firmly in a three‑jaw chuck or collet to eliminate run‑out. Verify that the drill is centered before starting the spindle.
Safety: Always wear appropriate eye protection. Use cutting fluid or lubricant when drilling ferrous metals to prolong bit life and improve chip evacuation. Check the drill for wear or damage before each use.
