Hertel 71206205 Jobber Drill Bit Wire 3 Hss Oxide

Product Description

The HERTEL 71206205 is a jobber-length drill bit sized to wire gauge number 3, with a decimal diameter of 0.2130 inches. It is manufactured from high speed steel with an oxide coating that reduces friction and extends tool life in general-purpose drilling applications. The bit features a 118-degree standard point angle, a two-flute regular spiral configuration, and a web-thinned, tapered web for improved chip evacuation. The straight-cylindrical shank measures 0.2130 inches in diameter. This bit is intended for use by machinists, maintenance technicians, and tradespeople working in metal fabrication, mechanical assembly, and general industrial drilling tasks.

This bit is suited for drilling ferrous and non-ferrous metals, plastics, and wood composites in shop and field environments. The right-hand cut and standard point geometry make it compatible with conventional drill presses, hand drills, and drill motors commonly used in HVAC, plumbing, electrical, and general mechanical trades. The 3-3/4 inch overall length and 2-1/2 inch flute length provide adequate reach for typical jobber-length drilling requirements without excessive deflection.

Key Features

• Wire size number 3 with a 0.2130 inch decimal diameter for precise hole sizing
• High speed steel construction provides durability across a broad range of materials
• Oxide coating reduces friction and helps resist heat buildup during cutting
• 118-degree standard point angle for general-purpose drilling on flat and curved surfaces
• Web-thinned, tapered web improves chip flow and reduces thrust requirements
• Straight-cylindrical shank compatible with standard drill chucks

Compatibility

Designed as a general-purpose jobber-length drill bit for use in standard 3-jaw drill chucks accepting a 0.2130 inch straight shank, suitable for drill presses, portable hand drills, and drill motors across trade and industrial applications.

Installation Notes

This bit is installed and operated by machinists, maintenance technicians, and trade professionals using standard drill equipment. Always secure the workpiece before drilling and ensure the chuck is fully tightened before operation. Wear appropriate eye protection per applicable safety standards. Do not exceed the rated speed range for the material being drilled, and allow the bit to cool or apply cutting fluid when drilling harder metals to prevent premature wear.
