Chicago-latrobe 69041 Jobber Drill Bit No. 41 Hss 135

Product Description

The CHICAGO-LATROBE 69041 is a jobber-length drill bit in wire gauge size No. 41, ground to a 0.0960-inch diameter from high-speed steel with a bright uncoated finish. Built to the Series 150DH heavy-duty specification, it features a 135-degree split point for fast engagement and reduced walking on entry, and a parabolic flute design that clears chips aggressively at higher feed rates. Overall length is 2-3/8 inches, with a 1-3/8-inch flute length. The straight-cylindrical shank measures 0.0960 inches in diameter with a 1.0-inch shank length, compatible with standard drill chucks. Diameter tolerance is held to -0.0005 to 0.0000 inches, keeping holes in spec without reaming in many light-duty applications. Installed by machinists, maintenance technicians, and sheet-metal workers.

The 69041 is suited for drilling steel alloy and similar ferrous workpiece materials in production and maintenance environments. The parabolic flute geometry and web-thinned, tapered web construction reduce thrust requirements in small-diameter work, making this bit practical for bench drill presses, handheld electric drills, and CNC drill stations running small wire-gauge holes. It ships as a single bit per package, with a minimum order quantity of 12 units, making it appropriate for shop stocking in jobber assortments or line-side replenishment bins.

Key Features

• 135-degree split point reduces walking and lowers thrust at drill entry
• Parabolic flute geometry promotes efficient chip evacuation at higher feed rates
• Web-thinned tapered web reduces cutting resistance on small-diameter bores
• High-speed steel construction with bright uncoated finish for general-purpose ferrous drilling
• Diameter tolerance of -0.0005 to 0.0000 inches for consistent hole sizing
• Heavy-duty Series 150DH grade for extended service life in production use

Compatibility

Designed for drilling steel alloy and comparable ferrous materials; fits any standard drill chuck or collet accepting a 0.0960-inch straight-cylindrical shank.

Installation Notes

Install in a properly rated drill press, hand drill, or CNC spindle before powering the machine. Secure the shank fully in the chuck and verify concentricity before cutting, particularly in precision applications where hole-location tolerance is tight. Use cutting fluid appropriate for steel alloy when drilling at sustained production rates to preserve cutting-edge life. Inspect the split point for chipping or wear before each setup; a damaged point on a small-diameter bit will cause oversize holes and shank deflection.
