Hertel 71206494 Jobber Drill Bit Wire 32 Hss Oxide

Product Description

The HERTEL 71206494 is a jobber-length twist drill bit designed for general-purpose drilling in metal, wood, and plastics. It is manufactured from high speed steel with an oxide coating that helps reduce friction and extend tool life in production and maintenance drilling applications. The bit is ground to a 118-degree standard point angle with web thinning for easier penetration and reduced thrust. With an overall length of 2.75 inches and a flute length of 1.625 inches, this bit fits standard drill chucks and is sized to wire gauge No. 32, equivalent to 0.1160 inches in decimal. The straight-cylindrical shank seats securely in keyed or keyless chucks. Installation is performed by machinists, maintenance technicians, and trade professionals across HVAC, plumbing, and electrical applications.

This bit is suited for light-duty hole-making tasks in sheet metal, conduit, pipe hangers, brackets, and similar thin-material work encountered in mechanical and electrical trade service. The 0.1160-inch diameter falls within the 0.1000 to 0.1500 inch drill size range, making it appropriate for pilot holes, wire clearance holes, and small-fastener through-holes. The right-hand spiral flute geometry clears chips efficiently in both hand-held and bench-drill applications. It is sold individually with a minimum order quantity of 12 pieces.

Key Features

• 118-degree standard point angle with web thinning for reduced entry thrust
• High speed steel construction with oxide coating for reduced friction
• Right-hand cut, regular spiral, two-flute design for efficient chip evacuation
• Straight-cylindrical shank compatible with standard keyed and keyless chucks
• General-purpose grade suitable for metal, plastics, and light-duty materials

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with any standard drill chuck accepting a 0.1160-inch straight-cylindrical shank.

Installation Notes

This bit is installed by securing the straight-cylindrical shank firmly in a keyed or keyless drill chuck before use. Always ensure the workpiece is clamped securely to prevent rotation during drilling. Use appropriate cutting fluid or lubricant when drilling ferrous metals to extend bit life and maintain dimensional accuracy. Inspect the cutting edges before each use and replace bits showing signs of dullness, chipping, or heat discoloration.
