Hertel 85704583 Jobber Drill Bit 3/8 Inch Hss Tin

Product Description

The HERTEL 85704583 is a jobber-length drill bit designed for general-purpose metal drilling in trade and industrial applications. It is manufactured from high speed steel (HSS) with a titanium nitride (TiN) coating that extends cutting life by reducing friction and surface wear. The bit measures 3/8 inch (0.3750 inch decimal) in diameter with a 5-inch overall length and a 3-5/8-inch flute length. The 118-degree standard point angle suits a wide range of common materials. A web-thinned, tapered web configuration reduces the thrust required to start the cut and helps center the bit at entry.

This bit is suited for use in sheet metal fabrication, plumbing rough-in, HVAC duct and bracket work, electrical panel and conduit installation, and general mechanical assembly. It handles ferrous and non-ferrous metals, plastics, and similar materials encountered in residential and light commercial trade work. The straight-cylindrical shank fits standard 3-jaw drill chucks on corded drills, cordless drills, and drill presses. It is sold individually and is appropriate for field service kits and shop inventory.

Key Features

• 3/8 inch diameter with 0.3750 inch decimal precision for consistent hole sizing
• TiN coating reduces friction and extends cutting edge life compared to uncoated HSS
• 118-degree standard point angle for general-purpose drilling across common trade materials
• Web-thinned tapered web reduces entry thrust and improves centering
• Regular spiral, right-hand cut with 2 flutes for efficient chip evacuation
• Straight-cylindrical shank fits standard 3-jaw chuck equipment

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with any standard 3-jaw drill chuck accepting a 3/8-inch straight-cylindrical shank.

Installation Notes

Installation of this bit is performed by licensed tradespeople and qualified mechanics using standard drill equipment. Secure the shank fully in a 3-jaw chuck and verify runout before drilling. Always wear appropriate eye protection and secure the workpiece before beginning the cut. Reduce feed pressure as the bit breaks through the material to prevent catch and bit deflection.
