Chicago-latrobe 41692 Jobber Drill Bit Size 22 Hss Tin

Product Description

The CHICAGO-LATROBE 41692 is a jobber length drill bit in wire gauge size 22, equivalent to 0.1570 inches in diameter. Built from high speed steel with a titanium nitride (TiN) coating, this bit is engineered for heavy-duty drilling in demanding materials. It features a 135-degree split point that self-centers on contact, reducing walking and the need for a center punch. With an overall length of 3.125 inches and a 2-inch spiral flute, it provides reliable chip evacuation and consistent hole quality. Machinists, maintenance techs, and fabricators use this bit in production and field drilling applications.

This bit is designed for cutting cast iron, stainless steel, and carbon steel. The right-hand spiral flute geometry and web-thinned split point reduce thrust load, which is especially useful when drilling work-hardened or abrasion-resistant alloys. It fits standard drill chucks with a straight cylindrical shank and suits both handheld and bench-mounted drilling equipment. The Series 150ASP-TN designation indicates a high-performance, TiN-coated jobber format built to NAS 907 Type B standards, making it appropriate for aerospace-adjacent and precision metalworking environments.

Key Features

• Wire gauge size 22, decimal equivalent 0.1570 inches
• 135-degree split point with web thinning for self-centering and reduced thrust
• Titanium nitride (TiN) coating for extended wear resistance and reduced friction
• High speed steel construction rated for heavy-duty grade performance
• Right-hand cut with regular spiral flute for positive chip removal
• Meets NAS 907 Type B standard

Compatibility

Designed as a standard jobber length drill bit compatible with any drill chuck accepting a straight cylindrical shank; suitable for use in handheld power drills, drill presses, and CNC drilling operations on cast iron, stainless steel, and steel workpieces.

Installation Notes

Installation is performed by machinists or maintenance technicians using any drill press, hand drill, or CNC machine with a compatible chuck. Ensure the shank is fully seated and secured in the chuck before operation. When drilling stainless steel or cast iron, use appropriate cutting fluid to preserve coating life and maintain dimensional accuracy. Inspect the cutting edge for wear regularly, as a dull split-point tip will increase thrust and reduce hole quality.
