Chicago-latrobe 41706 Jobber Drill Bit 36 Tin Hss

Product Description

The CHICAGO-LATROBE 41706 is a jobber-length drill bit in wire gauge size 36, measuring 0.1065 inches in diameter. Built from high-speed steel with a titanium nitride coating, it delivers extended tool life in demanding drilling applications. The 135-degree split point reduces walking and lowers thrust force, making it well-suited for initiating holes without a center punch. A tapered web with web thinning further reduces cutting resistance. At 2.5 inches overall length with a 1.4375-inch flute length, this is a compact, precise bit intended for professional machinists, maintenance technicians, and metalworking tradespeople who need consistent performance in tight tolerances.

This bit is designed for drilling cast iron, stainless steel, and carbon steel in production and maintenance settings. The straight-cylindrical shank seats securely in standard drill chucks on both handheld and benchtop equipment. Its regular-spiral, right-hand-cut flute geometry provides efficient chip evacuation in ferrous metals. The TiN coating reduces friction and heat buildup, extending edge life compared to uncoated HSS bits, particularly in repetitive or high-cycle drilling operations common in fabrication shops and field service environments.

Key Features

• Wire gauge size 36, 0.1065-inch decimal diameter for precision hole sizing
• 135-degree split point with web thinning reduces thrust and eliminates center-punch requirement
• Titanium nitride coating extends tool life and reduces heat in ferrous metal drilling
• High-speed steel construction rated for heavy-duty grade performance
• Right-hand cut, regular-spiral flute promotes consistent chip evacuation
• Meets NAS 907 Type B standards for dimensional and performance consistency

Compatibility

Designed as an OEM-style jobber-length drill bit for use with standard drill chucks accepting a straight-cylindrical shank; primary workpiece materials include cast iron, stainless steel, and steel.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance technicians familiar with metalworking safety practices. Secure the shank fully in the drill chuck before operation and confirm the workpiece is properly clamped. Always wear appropriate eye protection and follow applicable shop safety protocols. Inspect the cutting edge before each use and replace the bit if chipping or excessive wear is observed.
