Chicago-latrobe 41008 1/8 Inch Hss Jobber Drill Bit 135 Degree

Product Description

The CHICAGO-LATROBE 41008 is a jobber length drill bit designed for general-purpose and heavy duty metal drilling applications. Built from M7 high speed steel with a bright uncoated finish, this bit features a 135-degree notched split point that reduces walking on contact and lowers the thrust needed to start a hole. The parabolic flute geometry promotes fast chip evacuation and helps prevent clogging when drilling into steel and similar materials. At 0.1250 inches in diameter and 2.75 inches overall length, it fits standard drill chucks and is well suited for production and maintenance tasks where consistent hole quality matters.

The 41008 is intended for right hand cutting in steel and comparable ferrous workpiece materials. Its straight cylindrical shank with a 0.1250-inch shank diameter seats securely in standard three-jaw chucks on hand drills, drill presses, and CNC drilling equipment. The web-thinned tapered web reduces cutting force and heat buildup, making it a practical choice for repetitive hole-making in sheet metal, plate, structural steel, and fabricated components. Licensed contractors, maintenance machinists, and trade professionals working in industrial and light manufacturing environments will find this bit reliable for day-to-day drilling tasks.

Installation Notes

Installation of drill bits should be performed by machinists, maintenance technicians, or qualified trade professionals familiar with rotating cutting tools. Always power down and fully de-energize the drilling equipment before inserting or removing a bit, and confirm the chuck is tightened securely before operation. Wear appropriate eye protection and follow applicable OSHA and shop-safety guidelines when operating drilling equipment. Do not exceed the recommended speed range for the workpiece material and bit diameter.
