Why Choose Our Fractional Jobber Drills?
When you select our Fractional Drills – Jobber Length, you’re investing in a tool that delivers:
- Consistent Accuracy – Tight tolerances ensure each hole meets exact dimensions.
- Extended Tool Life – The TiN coating reduces friction and wear, allowing more holes per bit.
- Enhanced Safety – Balanced design reduces kick‑back, protecting both operator and equipment.
- Versatility – Ideal for drilling steel, stainless steel, aluminum, brass, and most non‑ferrous alloys.
- Cost‑Effective Performance – Fewer replacements mean lower overall drilling costs.
Applications
These jobber‑length fractional drills are the go‑to choice for:
- Machining and CNC operations
- Prototype and production tooling
- Aerospace component fabrication
- Automotive engine block and chassis work
- Maintenance, repair, and overhaul (MRO) tasks
- General workshop and shop‑floor drilling
Installation & Use Tips
- Secure the drill bit in a high‑quality chuck or collet to avoid run‑out.
- Set the spindle speed according to material hardness (e.g., 2,500–3,500 RPM for steel).
- Use cutting fluid or lubricant when drilling ferrous metals to extend tool life.
- Apply steady pressure; avoid forcing the bit, which can cause premature wear.
- Inspect the tip regularly for wear or coating damage; replace when the cutting edge blunts.
