Chicago-latrobe 42023 Jobber Drill Bit 23/64 in Hss Ticn

Product Description

The CHICAGO-LATROBE 42023 is a jobber length drill bit designed for heavy-duty drilling in steel and similar ferrous materials. It is manufactured from M7 high speed steel and finished with a TiCN (titanium carbonitride) coating for improved surface hardness and wear resistance. The bit features a 135-degree notched point that reduces walking on contact and enables faster penetration with less feed pressure. A parabolic flute profile promotes efficient chip evacuation during deep-hole drilling. This bit is installed and used by machinists, millwrights, pipefitters, and general trade mechanics working in fabrication and field environments.

The 42023 is suited for production and maintenance drilling in steel workpieces across residential, commercial, and industrial settings. The straight-cylindrical shank fits standard three-jaw drill chucks without modification. With a 23/64 inch diameter and 4-7/8 inch overall length, it fits typical hand drills, drill presses, and CNC setups where a jobber-length bit is specified. It is part of the CHICAGO-LATROBE Series 150WLPN, a heavy-duty line intended for demanding metal-cutting applications.

Key Features

• M7 high speed steel construction for heavy-duty service in steel workpieces
• TiCN coating increases surface hardness and extends tool life compared to uncoated HSS
• 135-degree notched split point reduces bit walking and lowers thrust requirements
• Parabolic flute geometry improves chip flow and reduces packing in deep holes
• Web-thinned, tapered web configuration for balanced cutting performance
• Straight-cylindrical shank fits standard drill chucks without adapters

Compatibility

Designed as an OEM-style jobber length drill bit compatible with standard three-jaw drill chucks accepting a 0.3594 inch straight shank, suitable for use in hand drills, drill presses, and CNC drilling equipment where a 23/64 inch diameter bit is required.

Installation Notes

This bit is installed by securing the straight-cylindrical shank firmly in a properly sized drill chuck before use. De-energize and lock out all power to drilling equipment before changing bits. Use appropriate cutting fluid or coolant when drilling steel to manage heat buildup, as the bit does not support internal coolant delivery. Inspect the cutting edges and coating condition before each use and replace the bit if chipping or excessive wear is observed.
