Chicago-latrobe 69023 Jobber Drill Bit Wire 23 Hss

Product Description

The CHICAGO-LATROBE 69023 is a jobber-length drill bit designed for drilling steel alloy and similar ferrous materials in professional shop and field environments. Built from high-speed steel (HSS) with a bright, uncoated finish, this bit features a 135-degree split point that reduces walking on contact and lowers the thrust needed to start a hole. The parabolic flute geometry promotes aggressive chip evacuation, making it well suited for deeper holes in tough materials. At 0.1540 inches in diameter (wire size 23) and 3.125 inches overall length, this is a heavy-duty, general-purpose bit for machinists, maintenance mechanics, and metalworking tradespeople.

The 69023 is sized for wire gauge 23 applications, covering a decimal diameter of 0.1540 inches. It fits standard drill chucks and accepts both benchtop drill presses and hand-held power drills. The straight cylindrical shank diameter of 0.1540 inches ensures a positive grip in conventional three-jaw chucks. Primary workpiece material is steel alloy, though the HSS construction handles a range of ferrous metals encountered in HVAC, plumbing, and electrical rough-in work where precise small-diameter holes are required.

Key Features

• 135-degree split point reduces drill walking and decreases feed pressure on entry
• Parabolic flute design promotes fast, efficient chip removal in deep-hole drilling
• High-speed steel construction rated for heavy-duty metalworking applications
• Bright uncoated finish allows easy visual inspection for wear or damage
• Web-thinned, tapered web configuration reduces cutting resistance
• Series 150DH heavy-duty grade with diameter tolerance of -0.0007 to 0.0000 inches

Compatibility

Designed as a jobber-length replacement drill bit for applications requiring wire gauge size 23 (0.1540 inches) with a straight cylindrical shank, compatible with standard three-jaw drill chucks on benchtop and handheld power drills.

Installation Notes

Installation and use of drill bits should follow safe machine-tool practices. Secure the workpiece firmly before drilling and ensure the chuck is tightened properly before starting the spindle. Always wear appropriate eye protection when drilling metal. Inspect the cutting edges before each use and remove the bit from service if chipping, cracking, or excessive wear is observed.
