Machinists and metalworkers, this Drill America combined drill and countersink bit (also called a center drill) is a workshop essential. It's designed to create precise center holes in workpieces so they can be mounted and turned between centers on a lathe. It's a 2-in-1 tool: the small pilot tip drills the starter hole, and the wider angled section cuts a perfect 60-degree countersink for the lathe's center to sit in. Made from high-speed steel (HSS) with a black oxide finish for extra lubricity and heat resistance. The spiral flute design helps pull chips up and out of the hole, keeping things clean and preventing clogging. The round shank fits into standard drill chucks and collets. This is a professional-grade tool for accurate, clean starts in metal, plastic, or wood. A must-have for any serious home shop or professional machinist.
