Chicago-latrobe 57208 Jobber Drill Bit 1/8 in Hss

Product Description

The CHICAGO-LATROBE 57208 is a jobber-length twist drill bit designed for general-purpose drilling in metal, wood, and composite materials. It measures 0.1250 inches in diameter with a 2-3/4 inch overall length and features a 118-degree split point that reduces walking on contact and improves hole entry accuracy. The bit is manufactured from high speed steel with an oxide finish that provides light corrosion resistance and reduces friction during cutting. The straight-cylindrical shank seats securely in standard drill chucks. This is a professional-grade tool suited for HVAC techs, plumbers, electricians, and general trade use wherever a reliable small-diameter bit is needed.

The 57208 fits residential and commercial trade applications requiring clean, precise 1/8 inch holes. Common uses include sheet metal drilling, electrical panel work, conduit support mounting, bracket fabrication, and pilot hole work in light structural members. The right-hand spiral flute design clears chips efficiently during through-drilling in thin and medium stock. At 2-3/4 inches overall, the bit works with standard hand drills, drill presses, and right-angle drill attachments commonly used on job sites.

Installation Notes

A licensed tradesperson or qualified technician should ensure the drill and workpiece are secured before drilling. Always wear appropriate eye protection when operating rotary cutting tools. Match drill speed to workpiece material — lower RPM for harder metals, higher RPM for softer materials and plastics. Inspect the cutting edges before use and replace the bit if chipping or excessive wear is present.
