Hertel 66694316 Jobber Drill Bit No. 32 Hss Tin

Product Description

The HERTEL 66694316 is a No. 32 wire-gauge jobber-length drill bit ground from high speed steel and finished with a titanium nitride (TiN) coating. The bit measures 0.116 inches in diameter and 2-3/4 inches overall, with a 1-5/8-inch spiral flute length. A 135-degree split point reduces walking and allows the bit to start without a center punch on most work surfaces. The web-thinned, tapered web construction reduces thrust and improves chip evacuation. This is a heavy-duty grade bit rated to the NAS specification, suited for production drilling in metal fabrication and maintenance environments.

The 66694316 is a general-purpose holemaking tool for use in ferrous and non-ferrous materials. Its jobber-length configuration is standard for benchtop drill presses, hand drills, and CNC drilling operations where moderate reach is required. The straight-cylindrical shank seats directly in standard drill chucks without adapters. The TiN coating extends surface hardness and reduces heat buildup during continuous-use cycles, making this bit appropriate for repetitive drilling tasks in sheet metal, structural steel, and similar materials.

Key Features

• No. 32 wire size, 0.116-inch decimal diameter for precision hole sizing
• 135-degree split point minimizes walking and reduces required entry thrust
• TiN coating increases surface hardness and extends tool life over uncoated HSS
• Web-thinned tapered web improves chip flow and lowers cutting resistance
• Right-hand spiral flute, regular helix - compatible with standard right-hand drill equipment
• Heavy-duty grade, NAS specification designation for industrial use

Compatibility

Designed as a standard jobber-length drill bit with a straight-cylindrical shank fitting any drill chuck sized to accept a 0.116-inch shank, including keyed and keyless chucks on portable hand drills, drill presses, and CNC drilling machines.

Installation Notes

A licensed machinist or qualified maintenance technician should verify chuck capacity and spindle speed before use. Secure the workpiece firmly before drilling to prevent rotation during bit engagement. Disconnect power to the drill press or deactivate the CNC program before changing bits. Do not apply side-loading force to a jobber-length bit, as deflection can cause breakage or an out-of-tolerance hole.
