Drill America 19/32in HSS Jobber Bit
The Drill America 19/32in HSS Black Oxide Jobber Length Drill Bit is a precision cutting tool made from high-speed steel with a black oxide surface treatment. It suits machinists and maintenance technicians drilling ferrous metals in professional workshops. Buyers needing carbide tips or specialised coatings for hardened alloys should consider other tooling options.
Straight Shank Install Notes
The bit features a standard straight shank that fits directly into three-jaw drill chucks without adapters. Ensure the chuck jaws grip the shank firmly and run the drill at appropriate speeds for the material. A common issue is premature wear or breakage when excessive feed pressure is applied without adequate lubrication.
