Hertel 71206213 Jobber Drill Bit Wire 4 Hss Oxide

Product Description

The HERTEL 71206213 is a jobber-length twist drill bit sized to wire gauge 4, with a decimal diameter of 0.2090 inches. Built from high speed steel (HSS) with an oxide coating, it is engineered for general-purpose drilling in metal, wood, and plastic. The standard 118-degree split point starts cleanly without a center punch in many applications. At 3.75 inches overall length with a 2.5-inch flute length, it fits standard drill chucks and drill presses used daily in mechanical, electrical, and fabrication work. The straight-cylindrical shank seats securely in both keyed and keyless chucks.

This bit is suited for use in light manufacturing, electrical rough-in, HVAC sheet metal work, plumbing rough-in, and general maintenance applications. The wire gauge 4 size falls in the 0.2000 to 0.2500 inch decimal range, making it a common selection when drilling pilot holes, clearance holes for fasteners, or access holes in light-gauge steel, aluminum, copper, and similar materials. It is sold individually with a minimum order quantity of 12 units per order.

Key Features

• Wire size 4 (0.2090 inches decimal) for precise hole sizing in the 0.2000 to 0.2500 inch range
• High speed steel construction provides durability across metals, plastics, and wood
• Oxide coating reduces friction and helps resist corrosion during storage and use
• 118-degree standard point angle with web-thinned, tapered web for reduced thrust and cleaner entry
• Regular spiral flute with right-hand cut evacuates chips efficiently during drilling
• Straight-cylindrical shank at 0.2090 inches diameter fits standard drill chucks without adapters

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with any standard keyed or keyless drill chuck accepting straight-cylindrical shanks up to 0.2090 inches in diameter, including portable drills, drill presses, and CNC drilling setups used in trade and light industrial applications.

Installation Notes

Install in a properly rated drill or drill press with the chuck tightened fully before operation. Disconnect or de-energize any equipment being worked on before drilling into assemblies containing live wiring or pressurized lines. Use appropriate cutting fluid or lubricant when drilling ferrous metals to extend bit life and maintain hole quality. Inspect the cutting edges before each use and replace the bit if chipping or dulling is evident to avoid oversized holes or workpiece damage.
