Its compact jobber length and 0.0890-inch diameter make it a practical choice for close-tolerance work, pilot holes, and repetitive production drilling where consistent sizing is required. The oxide finish provides a degree of lubricity and surface hardness for extended service life under normal shop conditions. Each unit is sold individually, with a minimum order quantity of 12 pieces.
