Extension Tap 3/4 -10 Cobalt MPN:1625534127
Extension Tap 3/4 -10 Cobalt is a premium tool designed for cutting threads on external diameters of existing holes or threaded rods that may not fully accommodate other tap sizes. Made from advanced cobalt high-speed steel material, it provides extreme hardness and wear resistance against abrasive wear when tapping into difficult materials such as stainless steel, alloy steels, brass or plastics. Its extension feature offers precision alignment by preventing misalignment of the tap's lead-in to the workpiece, thus resulting in better thread engagement and more accurate threads. Offered in a common 3/4-inch size by -10 UNC standard coarse thread design, this versatile extension tap is ideal for professional machinists, technicians, fabricators or hobbyists working on metalworking, automotive repair shops, or aerospace applications where precise threads and consistent quality are essential for reliable performance.
