Hertel 83240432 Jobber Drill Bit 43/64 Inch Hss Oxide

Product Description

The HERTEL 83240432 is a jobber-length twist drill bit designed for general-purpose drilling in metal, wood, and composite materials. Built from high speed steel with an oxide coating, this bit handles the friction and heat common in production drilling environments. It measures 43/64 inches (0.6719 inches decimal) in diameter with an overall length of 7-5/8 inches and a flute length of 5-5/8 inches. The 118-degree standard point angle suits a wide range of work materials without requiring a specialized grind. The web-thinned, tapered web configuration reduces thrust at the cutting tip and helps keep the point centered on entry. Machinists, maintenance technicians, and general fabricators reach for this bit on drill presses and hand drills alike.

This bit is suited for general-purpose applications across light manufacturing, maintenance and repair operations, and field fabrication. The straight-cylindrical shank seats cleanly in standard drill chucks without requiring a Morse taper adapter. The 43/64-inch diameter sits in the larger end of the fractional drill range, making it a common choice when drilling clearance holes for bolts or enlarging existing bores. It is sold individually and is a direct drop-in replacement wherever a 43/64-inch jobber-length HSS drill is called out on a work order.

Key Features

• High speed steel construction with oxide coating for heat and wear resistance
• 118-degree standard point angle for broad material compatibility
• Web-thinned tapered web reduces drilling thrust and improves centering
• Regular spiral, 2-flute design promotes chip evacuation during drilling
• Straight-cylindrical shank fits standard 3-jaw drill chucks
• Jobber-length OAL of 7-5/8 inches provides reach without sacrificing rigidity

Compatibility

Designed as a general-purpose replacement jobber-length drill bit for any application requiring a 43/64-inch (0.6719-inch decimal) straight-shank HSS drill in a standard drill chuck.

Installation Notes

Install in a properly sized drill chuck and tighten with a chuck key before operation. Secure the workpiece firmly to prevent rotation during drilling. Verify spindle speed is appropriate for the material being drilled — harder materials require lower RPM. Inspect the cutting edges and point geometry before use; a chipped or dull tip increases heat, deflection, and the risk of bit breakage.
