RUKO HGB-DIN352-HSSCo-60°-M12x1.75mm Hand Tap

Cutting precise M12 x 1.75 mm metric coarse threads in tough materials like steel, stainless steel, and cast iron demands a tap that stays sharp and resists wear. The RUKO HGB-DIN352-HSSCo-60°-M12x1.75mm hand tap is built from high-speed steel with cobalt (HSS-Co) for superior heat resistance and durability, making it a reliable choice for demanding workshop tasks.

Who is it for

This hand tap is intended for machinists, metalworkers, and maintenance professionals who need to create or repair internal threads in through holes and blind holes. It suits general-purpose threading across a range of ferrous and non-ferrous metals.

Main features

• Metric coarse thread M12 with 1.75 mm pitch, conforming to DIN 352.
• 60° thread angle and ISO 2 (6H) tolerance class for standard thread fit.
• Three flutes for efficient chip evacuation and smooth cutting.
• Right-hand cutting direction for conventional threading operations.
• Bright surface finish to reduce friction and improve chip flow.
