Chicago-latrobe 45693 Jobber Drill Bit Wire 23 Hss

Product Description

The CHICAGO-LATROBE 45693 is a jobber-length drill bit designed for high-performance drilling in demanding trade and industrial applications. Built from high-speed steel with an oxide coating, this bit measures 0.1540 inches in diameter (Wire Size 23) and features a 135-degree split point that reduces walking and lowers thrust at entry. At 3.125 inches overall length with a 2-inch spiral flute, it delivers the reach and chip-clearing capacity needed for production drilling. The web-thinned, tapered web construction reduces cutting resistance while maintaining rigidity. This is a heavy-duty grade bit specified to NAS 907 Type B standards, suited for machinists, pipefitters, and maintenance technicians working in metal fabrication or mechanical service environments.

The 45693 is rated for use in cast iron, stainless steel, and carbon steel workpieces, making it a practical choice for HVAC and plumbing rough-in work, mechanical equipment installation, and general sheet metal and structural steel drilling. The straight-cylindrical shank fits standard drill chucks without adapters. Regular spiral geometry promotes consistent chip evacuation during through-hole drilling. This bit is sold individually but is subject to a minimum order quantity of 12 units per order.

Key Features

• 135-degree split point reduces bit walk and decreases entry thrust on hard metals
• High-speed steel construction with oxide coating for heat and wear resistance
• Web-thinned tapered web lowers cutting resistance in cast iron and stainless steel
• Right-hand cut, regular spiral flute for efficient chip removal
• Straight-cylindrical shank fits standard drill chucks directly
• Meets NAS 907 Type B specification for heavy-duty grade tooling

Compatibility

Designed as an OEM-style replacement and general-use jobber drill bit compatible with any standard drill chuck accepting a 0.1540-inch straight-cylindrical shank. Rated for cast iron, stainless steel, and carbon steel workpiece materials per the Series 150ASP specification.

Installation Notes

This bit is installed and operated by machinists, pipefitters, HVAC technicians, and maintenance trades using handheld or bench-mounted electric drills and drill presses. Secure the straight shank firmly in the chuck before operation and verify chuck key is removed before starting the tool. Use appropriate cutting fluid or coolant when drilling stainless steel or cast iron to extend bit life and manage heat buildup. Inspect the cutting edges for wear before each use and replace the bit if chipping or dulling is evident.
