Product Overview

Engineered for precision and durability, the Wire Gauge Drills – Jobber Length 012429 are the ideal choice for electricians, machinists, and hobbyists who demand exact hole sizes and long‑lasting performance. Crafted from premium high‑speed steel (HSS) and ground to a razor‑sharp edge, these drill bits provide clean, accurate cuts in a wide range of conductive and non‑conductive materials.

Key Features & Benefits

• Jobber Length Design: Optimized length offers superior chip clearance and increased rigidity for deep drilling without wobble.
• High‑Speed Steel (HSS) Construction: Resists heat buildup, maintains hardness, and delivers a longer service life compared to carbon steel alternatives.
• Precision Ground Cutting Edge: Guarantees tight tolerances and smooth finishes on copper, aluminum, steel, brass, and plastic.
• Standardized Wire Gauge Sizes: Perfect for creating exact gauge holes for wiring, conduit, and terminal installations.
• Versatile Compatibility: Fits 3/8" (10 mm) and 1/2" (13 mm) shank chucks on most corded and cordless drills, CNC routers, and drill presses.
• Corrosion‑Resistant Coating: Extends tool life in harsh workshop environments.
• Easy Identification: Laser‑etched size markings on the shank for quick selection on the job site.

Technical Specifications

Ideal Applications

These jobber‑length wire gauge drills are specifically designed for:

• Electrical conduit and outlet hole preparation
• Automotive wiring harness installation
• Metal fabrication and sheet metal work
• PCB prototype drilling
• Industrial equipment maintenance
• DIY home improvement projects

Installation & Usage Tips

1. Secure the drill bit firmly in the chuck, ensuring the laser‑etched size marking faces outward for quick identification.
2. Use a low to medium speed setting (RPM) for metal and a higher speed for plastics to avoid overheating.
3. Apply cutting fluid or lubricant when drilling hardened steel to prolong bit life.
4. Begin with a pilot hole if drilling larger diameters to reduce stress on the bit.
5. Clear chips regularly to maintain optimal cutting performance and prevent binding.
