Chicago-latrobe 54026 Jobber Drill Bit Wire 16 Cobalt Tin

Product Description

The CHICAGO-LATROBE 54026 is a cobalt jobber length drill bit in wire gauge size 16, with a decimal diameter of 0.1770 inches. It is built to Series 2550 specifications, featuring a 135-degree split point for fast, self-centering starts with minimal walking. The M42 cobalt steel construction is paired with a titanium nitride (TiN) coating for extended tool life and heat resistance. With a right-hand spiral flute and web-thinned tapered web, this bit is designed for heavy-duty cutting in hard and abrasive materials. A licensed HVAC tech, machinist, or metalworking professional will find this bit well-suited to demanding production and field applications.

This drill bit is designed for cutting stainless steel and general-purpose steel in production and maintenance environments. The TiN coating reduces friction and increases surface hardness, making it effective where standard high-speed steel bits fail prematurely. The straight cylindrical shank measures 0.1770 inches in diameter and 1.1875 inches in length, fitting standard drill chucks without adapters. The 2-flute spiral design provides efficient chip evacuation in both hand-held and machine-mounted applications. It meets DIN 338 and NAS 907 Type J standards, confirming dimensional and performance compliance for industrial use.

Key Features

• M42 cobalt steel construction for high heat and wear resistance in hard metals
• Titanium nitride (TiN) coating extends cutting life and reduces friction
• 135-degree split point reduces thrust and enables self-centering starts
• Web-thinned tapered web improves penetration rate in tough materials
• Right-hand regular spiral flute with 2-flute configuration for efficient chip removal
• Meets DIN 338 and NAS 907 Type J dimensional and performance standards

Compatibility

Designed for use in standard drill chucks accepting a 0.1770-inch straight cylindrical shank. Primary workpiece materials are stainless steel and steel. Suitable for use in drill presses, CNC drilling machines, and hand-held power drills where a wire size 16 jobber bit is specified.

Installation Notes

Install in a drill chuck rated for the intended spindle speed and material being drilled. Secure the shank fully before operation and confirm the chuck is tightened properly to prevent slipping. When drilling stainless steel or hardened alloys, use appropriate cutting fluid to manage heat buildup and maximize bit life. Follow applicable shop safety standards and machine manufacturer guidelines for speed and feed rates.
