Hertel 83240341 Jobber Drill Bit 17/32 Inch Hss Oxide

Product Description

The HERTEL 83240341 is a jobber-length drill bit designed for general-purpose metal drilling in shop, field, and maintenance applications. It measures 17/32 inch (0.5313 inch decimal) in diameter with a 6-5/8 inch overall length and a 4-13/16 inch flute length. The bit is manufactured from high speed steel with an oxide coating that reduces friction and helps extend service life under normal cutting conditions. The 118-degree standard point angle is the conventional geometry for drilling into mild steel, aluminum, and similar materials. A tapered web-thinned configuration reduces the thrust required to start and maintain a cut.

This drill bit is suited for use in drill presses, hand drills, and magnetic base drills across a range of trade and industrial settings including HVAC equipment fabrication, plumbing rough-in, electrical panel work, and general mechanical maintenance. The straight-cylindrical shank fits standard drill chucks without modification. Right-hand spiral flutes evacuate chips efficiently during through-hole and blind-hole drilling in ferrous and non-ferrous base metals.

Key Features

• 17/32 inch diameter with 0.5313 inch decimal equivalent for precise size selection
• High speed steel construction rated for general-purpose cutting in mild steel, aluminum, and similar materials
• Oxide coating reduces friction and helps resist heat buildup during drilling
• 118-degree standard point angle with web-thinned, tapered web for reduced thrust and easier starting
• 6-5/8 inch overall length with 4-13/16 inch flute length in a jobber-length format
• Straight-cylindrical shank fits standard three-jaw drill chucks without adapters

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with any standard drill chuck accepting a 0.5313 inch straight-cylindrical shank, including drill presses, handheld corded and cordless drills, and magnetic base drilling units.

Installation Notes

Secure the shank fully in the chuck and verify concentricity before drilling. Secure the workpiece with a clamp or vise — never hold by hand when drilling holes of this diameter. Power down and de-energize any equipment before drilling into live panels or pressurized assemblies. Cutting fluid or coolant is recommended for extended use in ferrous materials to preserve cutting edge life.
