Wire Gauge Drills – Jobber Length (012455)
Discover the ultimate solution for precision drilling in electrical, plumbing, and metalworking projects with our Wire Gauge Drills – Jobber Length (012455). Engineered from premium high‑speed steel (HSS), these drills provide exceptional hardness, wear resistance, and a razor‑sharp cutting edge that delivers clean, burr‑free holes every time. Whether you’re a professional contractor, an experienced tradesperson, or a DIY enthusiast, these jobber‑length wire gauge drills are designed to meet the demanding tolerances of wire, conduit, and small‑diameter hole applications.
Key Features & Benefits
- Jobber Length Design – Optimized 2‑inch (50 mm) shank for superior chip evacuation and deeper reach without sacrificing rigidity.
- Precision Wire Gauging – Ideal for drilling holes sized from 0.020 in to 0.250 in (0.5 mm to 6.35 mm) to accommodate a full range of wire gauges.
- High‑Speed Steel Construction – Heat‑treated HSS delivers maximum hardness (HRC 64‑66) for extended tool life and reduced wear.
- Flute Geometry – Two‑flute design provides excellent chip removal and smooth entry, minimizing vibration and reducing the risk of wire distortion.
- Versatile Application – Perfect for electrical conduit, HVAC ductwork, sheet metal, plastic, and light‑duty steel.
- Corrosion‑Resistant Coating – TiN or black oxide finish (depending on batch) protects against rust and prolongs performance.
- Consistent Accuracy – Ground tip geometry ensures a true center point for exact hole placement.
- Easy Identification – Laser‑etched size markings on the shank for quick selection on the job site.

Why Choose Our Wire Gauge Drills?
When it comes to drilling small‑diameter holes for wiring and conduit, the quality of your drill bit directly impacts both safety and efficiency. Our jobber‑length wire gauge drills are crafted with the same rigorous standards as industrial‑grade tooling, providing you with:
- Unmatched Durability: The hardened HSS core resists chipping, even under repeated use on harder substrates.
- Superior Accuracy: Ground tips reduce run‑out, ensuring holes are perfectly centered for seamless wire insertion.
- Reduced Downtime: The efficient chip‑evacuation design minimizes the need for frequent clearing, keeping your workflow smooth.
- Safety Compliance: Clean, burr‑free holes reduce the risk of wire damage and insulation breaches, meeting NEC and IEC standards.
- Cost‑Effective Performance: Longer tool life translates to fewer replacements and lower total cost of ownership.
Ideal Applications
These wire gauge drills excel in a variety of scenarios:
- Electrical wiring installations in residential, commercial, and industrial settings.
- HVAC duct and conduit drilling for air‑flow and refrigerant lines.
- Sheet‑metal fabrication for control panels, enclosures, and chassis.
- Prototype and hobbyist projects that require precise, repeatable hole sizes.
- Maintenance and repair work where clean, accurate holes are essential for component reliability.
Installation & Use Tips
For optimal results, follow these best practices:
- Secure the workpiece with a sturdy clamp or vise to prevent movement.
- Use a low‑speed setting (around 500–800 RPM) for metal and a higher speed (up to 1500 RPM) for plastic.
- Apply steady, moderate pressure; avoid forcing the drill, which can cause tip wear.
- Periodically withdraw the drill to clear chips and maintain cutting efficiency.
- Lubricate metal surfaces with cutting oil when drilling hard steel to extend tool life.
