Chicago-latrobe 54033 Jobber Drill Bit Size 23 Cobalt

Product Description

The CHICAGO-LATROBE 54033 is a jobber-length drill bit in wire gauge size 23, with a decimal diameter of 0.154 inches. Built from M42 cobalt high-speed steel and finished with a titanium nitride (TiN) coating, this bit is engineered for heavy-duty cutting in hard and abrasive materials. The 135-degree split point reduces walking and lowers thrust requirements on entry. Overall length is 3-1/8 inches with a 2-inch spiral flute, right-hand cut, and a straight-cylindrical shank. It conforms to DIN 338 and NAS 907 Type J standards. Licensed HVAC technicians, machinists, and metal fabricators use this bit in production and field drilling applications.

This bit is designed for drilling stainless steel and general steel workpieces where standard high-speed steel bits lose edge quickly. The M42 cobalt alloy retains hardness at elevated cutting temperatures, making it well suited for intermittent and continuous drilling in tough alloys. The TiN coating adds surface hardness and reduces friction at the cutting edge. The Series 2550 design with web-thinned, tapered web geometry improves chip evacuation in deep holes. This is a single-piece unit sold individually.

Key Features

• M42 cobalt high-speed steel construction for heat resistance and edge retention in hard metals
• TiN coating increases surface hardness and extends service life in abrasive materials
• 135-degree split point reduces thrust and minimizes bit walking on entry
• Web-thinned, tapered web improves chip clearance in deep drilling operations
• Meets DIN 338 and NAS 907 Type J specifications
• Right-hand spiral flute with straight-cylindrical shank fits standard drill chucks

Compatibility

Designed as an OEM-style replacement or direct-use jobber-length drill bit for any standard drill chuck accepting a 0.154-inch straight-cylindrical shank, conforming to NAS 907 Type J and DIN 338 specifications.

Installation Notes

Install in a drill press, hand drill, or CNC spindle with a chuck rated for the shank diameter before beginning any operation. Secure the workpiece before drilling and use appropriate cutting fluid when working stainless steel to control heat buildup. Follow applicable shop safety standards and machine guarding requirements. Never exceed the rated speed range for the bit diameter and material being drilled.
