Hertel 84580901 Jobber Drill Bit No 16 Hss 135 Deg

Product Description

The HERTEL 84580901 is a No. 16 wire-size jobber-length drill bit designed for production and general-purpose holemaking in metal, wood, and plastic. Built from high speed steel with an oxide coating for added lubricity and surface protection, it features a 135-degree split point that reduces walking and allows drilling to start without a center punch. The bit runs a regular spiral flute pattern with a web-thinned, tapered web for reduced thrust and cleaner chip evacuation. At 0.1770 inch diameter with a 3-3/8 inch overall length, it fits the standard jobber series length range used across most benchtop and handheld drilling setups.

This bit is suited for light industrial, maintenance, and fabrication applications where wire-gauge sizing is specified. The straight-cylindrical shank seats directly into standard drill chucks without an adapter. Two spiral flutes handle chip removal efficiently in both through-hole and blind-hole operations. The oxide finish extends tool life in moderate-duty cutting conditions. It is commonly used by machinists, sheet-metal workers, pipefitters, and general maintenance trades working to NAS specification requirements.

Key Features

• 135-degree split point reduces bit walking and lowers thrust requirements
• High speed steel construction handles moderate-duty drilling across common materials
• Oxide coating provides surface lubricity and light corrosion resistance
• Web-thinned tapered web reduces cutting resistance and improves chip flow
• Regular right-hand spiral flute for efficient chip evacuation
• Straight-cylindrical shank fits standard drill chucks without adapters

Compatibility

Designed as a jobber-series replacement drill bit for any application calling for a No. 16 wire-size (0.1770 inch) straight-shank bit conforming to NAS specification.

Installation Notes

Secure the shank fully in the drill chuck before operation and verify chuck key is removed before powering the tool. Ensure drilling speed is appropriate for the material being cut — excessive RPM shortens tool life and can damage the cutting edge. Wear appropriate eye protection and secure the workpiece to prevent rotation. Cutting fluid is recommended for extended use in ferrous metals.
