Chicago-latrobe 47241 Jobber Drill Bit 1.90mm Hss

Product Description

The CHICAGO-LATROBE 47241 is a jobber-length twist drill bit designed for general-purpose drilling in metal fabrication and maintenance environments. Built from high speed steel with an oxide finish for added lubricity and corrosion resistance, it features a 118-degree standard point angle and a web-thinned, tapered web configuration that reduces thrust during entry. The bit measures 1.90 mm in diameter (0.0748 inches) with an overall length of 46.00 mm (approximately 1.81 inches). Its right-hand spiral flute design efficiently clears chips while maintaining cutting stability in a range of workpiece materials.

This drill bit is suited for production and maintenance drilling in cast iron and steel. The straight-cylindrical shank seats securely in standard drill chucks across benchtop drill presses, hand drills, and CNC drilling centers. Conforming to DIN 338, it fits within a general-purpose application range from 0.0500 to 0.1000 inches in diameter. The Series 150 designation identifies it within the CHICAGO-LATROBE standard jobber line, making it a practical choice for shops, field technicians, and fabricators who drill small-diameter holes regularly.

• 118-degree standard point angle for general-purpose material entry
• Web-thinned, tapered web reduces drilling thrust and improves bit life
• Right-hand, regular spiral flute for efficient chip evacuation
• DIN 338 compliant for standardized dimensional consistency

Compatibility

Designed as a general-purpose jobber drill bit compatible with standard straight-shank drill chucks on hand drills, drill presses, and CNC drilling equipment capable of accepting a 0.0748-inch shank diameter.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance technicians familiar with metalworking equipment. Always secure the workpiece and verify chuck jaw engagement before operation. Use appropriate cutting fluid for steel applications to extend bit life and improve hole quality. Inspect the cutting edges for wear or chipping before each use and replace worn bits promptly to maintain dimensional accuracy.
