RUKO HGB-DIN352-HSS-60°-M45x4,50mm Conjunto de machos de roscar manuais

This RUKO hand tap set is engineered for cutting precise metric threads in unalloyed and low-alloyed steels up to 800 N/mm² tensile strength. The set includes three taps—taper, second, and bottoming—to handle through holes and blind holes with clean, accurate threads.

Highlights

• DIN 352 standard hand taps for M45 x 4.50 mm metric threads
• High-speed steel (HSS) construction for durability and long tool life
• 60° thread angle with ISO 2 (6H) tolerance for standard metric threads
• Right-hand cutting direction with square drive shank
• Bright uncoated surface; recommended core hole diameter 40.5 mm

In daily use

Use the taper tap to start the thread, the second tap to deepen it, and the bottoming tap to finish threads close to the bottom of blind holes. Apply a suitable cooling lubricant to improve cutting performance and extend tool life.
