Precision C115COMBCSET HSS-E Bronze 115-Piece Jobber Drill Set

The Precision C115COMBCSET is a 115-piece jobber drill set manufactured from HSS-E (high-speed steel with cobalt) in bronze finish, designed for general-purpose drilling in steel, cast iron, aluminum, and composite materials. The set is organized in a black foam-lined storage case with indexed compartments for rapid tool selection and includes both fractional and numbered/lettered drill sizes to provide comprehensive coverage for standard drilling applications. HSS-E material with bronze finish offers improved heat resistance and extended tool life compared to standard HSS, making this set suitable for manual and machine drilling operations at moderate to high speeds. The set arrives new and is compatible with standard 3/8-inch chuck drills, drill presses, and CNC machines accepting Morse taper or straight shank tooling. This is a versatile shop or manufacturing utility set for production environments, job shops, tool cribs, and maintenance departments.
