The Rotary Thread 15-pc Thread Restoration Master Kit, No. RTK2.1, is designed to repair and restore all threads, grooves, glands, keyways, gears, and more. The kit repairs inside or outside threads no matter the size, length, or diameter, without having to measure thread pitch, the company says. Each piece can be attached to a drill, die grinder, or Dremel tool. It features an embedded diamond abrasive, tuned for smooth control and easy thread repair. The kit is lightweight and can fix most hard-to-reach areas.
