RUKO HGB-DIN352-HSSCo-60°-M-8x1,25mm maschio a mano

This hand tap is a precision cutting tool for creating metric coarse threads with a nominal diameter of M8 and a pitch of 1.25 mm. Manufactured from high-speed steel with cobalt (HSS-Co), it delivers enhanced wear resistance and heat tolerance, making it suitable for demanding threading operations in steel, cast iron, and non-ferrous metals.

Advantages

The 60° thread angle and ground thread profile ensure accurate and clean thread cutting. With three flutes and a bright finish, chip evacuation is efficient, and the tool maintains sharpness over extended use. The right-hand cutting direction and ISO 2 (6H) tolerance class provide compatibility with standard metric fasteners.

Suitable for

• General purpose threading in through and blind holes
• Steel, cast iron, and non-ferrous metal workpieces
• Manual or machine tapping operations with external coolant supply
