Precision‑engineered wire gauge drills designed for professional metalworkers, electricians, and CNC technicians who demand accuracy and durability. The Jobber Length (012436) series delivers the perfect balance between reach and rigidity, making it ideal for deep‑hole drilling in a wide range of conductive and non‑conductive materials.

Key Features & Benefits

• Jobber Length Design: 3‑inch overall length provides optimal depth while maintaining a compact profile for tight‑space applications.
• High‑Speed Steel (HSS) Construction: Heat‑treated HSS bits resist wear and retain sharpness even after extended use.
• Precision Wire Gauge Sizes: Includes a full set of standard wire gauge diameters (30‑ gauge to 10‑ gauge) for exact hole sizing.
• Flute Geometry Optimized for Clean Cuts: Reduces burr formation and improves chip evacuation.
• Versatile Application: Perfect for drilling pilot holes, creating wire‑sized clearance, and preparing workpieces for wiring or fastening.
• Corrosion‑Resistant Finish: Double‑coated surface extends tool life in humid or oily environments.
• Easy Identification: Laser‑etched size markings on each drill for quick selection on the shop floor.
