Manufactured from premium grade cobalt steel for consistent and reliable performance, retaining a sharp cutting edge under extreme conditions. Featuring a special lip and spur point to ensure positive centering and sharp outer-corners. These stub drills are common spot weld sizes found in the automotive and trailer repair industry. The short flute design provides rigidity for hand held drilling of thin panels and sheet.
