Thread Repairing Tap, Die, and File Sets

Repair screw threads in a wide range of sizes. The dies are hex shaped for use with conventional wrenches. The taps have a square shank that's compatible with tap wrenches and tap holders for drill presses and drilling machines. With a plug chamfer, all taps have 3-5 chamfered threads and are suitable for thread repair in both through holes and closed-end holes.
