Chicago-latrobe 41602 1/32 Inch Hss Tin Drill Bit

Product Description

The CHICAGO-LATROBE 41602 is a jobber-length twist drill bit designed for precision drilling in ferrous metals and hard alloys. Built from high speed steel with a titanium nitride (TiN) coating, this bit delivers extended tool life and reduced heat buildup compared to uncoated HSS tooling. The 135-degree split-point tip provides fast penetration and accurate starting without a center punch in most applications. At 1/32 inch diameter with a 1-3/8 inch overall length, it is sized for tight-tolerance pilot holes and fine-diameter through-holes. Machinists, pipefitters, and fabricators working with cast iron, stainless steel, and carbon steel are the primary users of this series.

The 41602 is suited for production and maintenance drilling in ferrous metal fabrication, structural steel work, and mechanical assembly environments. Its NAS 907 Type B compliance makes it a fit for aerospace-adjacent and industrial manufacturing applications where dimensional and geometric standards are specified. The straight-cylindrical shank accepts standard drill chucks on both handheld and bench-mounted equipment, making it usable across a wide range of drilling setups. The Series 150ASP-TN designation identifies it within CHICAGO-LATROBE's high-performance coated jobber-length line.

Key Features

• TiN coating extends tool life and lowers friction during drilling in hard metals
• 135-degree split point reduces walking and improves entry accuracy on metal surfaces
• Web-thinned, tapered web construction reduces thrust requirements and chip packing
• 2-flute regular spiral geometry promotes chip evacuation in deep-hole drilling
• Straight-cylindrical shank fits standard drill chucks without adapters
• NAS 907 Type B compliant for use in controlled industrial and aerospace applications

Compatibility

Designed for drilling cast iron, stainless steel, and carbon steel workpieces per the Series 150ASP-TN application range. Compatible with any drill chuck accepting a 1/32 inch straight-cylindrical shank.

Installation Notes

This bit is installed by machinists, maintenance technicians, and fabricators using standard drill chucks on handheld, drill press, or CNC equipment. Secure the shank fully in the chuck before operation and verify runout on precision applications. Use cutting fluid or coolant appropriate for the workpiece material to extend bit life, especially when drilling stainless steel. Coolant-through is not supported on this bit; external lubrication only.
