Chicago-latrobe 54032 Cobalt Jobber Drill Bit Wire 22

Product Description

The CHICAGO-LATROBE 54032 is a cobalt jobber-length drill bit designed for high-performance drilling in tough materials. Built to M42 cobalt steel specification, this bit features a 135-degree split point for fast, self-centering starts with minimal walking. A titanium nitride (TiN) coating extends surface hardness and wear resistance during repeated use. The wire gauge No. 22 sizing translates to a decimal diameter of 0.1570 inches with a tight tolerance of -0.0007 to 0.0000 inches. At 3.125 inches overall length with a 2-inch flute, this bit is sized for standard jobber-length reach in hand-fed and machine-fed drilling operations. Licensed contractors and machining professionals working on production or maintenance tasks will find this a reliable daily-use tool.

This bit is engineered for drilling stainless steel and steel, where cobalt content and a TiN coating provide the heat resistance and edge retention that high-speed steel bits cannot match. The regular spiral flute and right-hand cut make it compatible with standard drill presses, CNC machines, and hand-held power drills. The straight-cylindrical shank seats securely in standard 3-jaw chucks across a wide range of equipment. Series 2550 heavy-duty grade positions this bit for demanding production environments and repetitive-cycle applications where bit life matters.

Key Features

• M42 cobalt steel construction for superior heat resistance in stainless steel and alloy steel drilling
• 135-degree split point with web thinning reduces thrust and eliminates the need for a center punch on most surfaces
• Titanium nitride (TiN) coating increases surface hardness and extends tool life
• Tapered web with web thinning improves chip evacuation and reduces torque demand
• Straight-cylindrical shank fits standard 3-jaw chucks without adapters
• Meets DIN 338 and NAS 907 Type J standards for dimensional and performance consistency

Compatibility

Designed as an OEM-specification jobber-length drill bit suitable for use in standard drill presses, CNC drilling equipment, and hand-held power drills accepting a straight-cylindrical shank. Intended for drilling stainless steel and steel workpieces per NAS 907 and DIN 338 Type J specifications.

Installation Notes

Installation is performed by machinists, maintenance technicians, and trade professionals operating drill presses or power drills. Secure the straight-cylindrical shank fully into a properly rated 3-jaw chuck before operation. Always run at the correct surface footage for the workpiece material and bit diameter — cobalt bits generate significant heat when feed rate or RPM is outside the recommended range. Inspect the cutting edges and TiN coating for wear before each use cycle and replace when the split point shows signs of rounding.
