TOPEX M3-M12 Tap and Die Set, 21 Pieces, Metric Thread, HSS Tools, with Wrenches and Accessories

A complete 21-piece tap and die set covering metric threads from M3 to M12, engineered for cutting, repairing, and re-threading in steel, aluminium, and other machinable metals. The high-speed steel tools stay sharp through repeated use, while the included wrenches and accessories give you everything needed to start threading right out of the case.

Advantages

High-speed steel construction delivers long-lasting cutting edges and resistance to wear. The set includes both taps and dies for each of the seven common metric sizes, so you can handle internal and external threads without buying separate kits. An adjustable tap wrench, a T-handle tap wrench, and an adjustable die stock provide secure tool holding for different working positions. A thread pitch gauge and screwdriver round out the kit for precise pitch identification and minor adjustments. All pieces fit in a blow-molded plastic case that keeps the set organized and protected during transport or storage.
