RUKO HGB-DIN352-HSSCo-60°-M14x2.00mm juego de machos de roscar manuales, métrico basto, HSS-E Co 5%, 3 piezas

This RUKO hand tap set is engineered for cutting metric coarse threads in tough materials, thanks to its HSS-E Co 5% cobalt steel construction. Unlike standard carbon steel taps, the 5% cobalt alloy retains hardness at high temperatures, making it suitable for stainless steel and other difficult-to-machine alloys. The set includes three taps—taper, second, and bottoming—allowing you to start threads easily and finish them to the bottom of blind holes. With a 60° thread angle and ISO 2 (6H) tolerance class, it produces precise, standard-compliant M14 x 2.00 mm threads.

Highlights

• Metric coarse thread M14 x 2.00 mm to DIN 352
• Made from HSS-E Co 5% high-speed steel with 5% cobalt for enhanced wear resistance
• Set of 3 taps: taper, second, and bottoming for through and blind holes
• Right-hand cutting direction with square shank for secure tool holding
• Bright uncoated finish for clean chip flow

In daily use

Whether you're threading a new hole or repairing damaged threads, this set provides the right tap for each stage. The taper tap starts the thread with a gradual lead, the second tap continues it, and the bottoming tap finishes threads close to the bottom of blind holes. The square shank fits standard tap wrenches and machine holders, ensuring a positive drive. The cobalt steel construction resists heat build-up, extending tool life even in stainless steel and cast iron.
