RUKO HGB-DIN352-HSS-60°-M30x3.50mm Hand Tap

Cutting precise M30 threads in tough materials demands a tap that stays sharp and accurate. The RUKO HGB-DIN352-HSS-60°-M30x3.50mm hand tap is built for exactly that, delivering clean threads in steel, cast iron, and non-ferrous metals without premature wear.

Who is it for

Machinists, metalworkers, and maintenance technicians who need a reliable finishing tap for general-purpose threading in through or blind holes. It suits workshops working with unalloyed and low-alloyed steels up to 800 N/mm² tensile strength.

Main features

• High-speed steel (HSS) construction for durability and heat resistance.
• DIN 352 standard dimensions ensure compatibility with common tap wrenches.
• Metric coarse thread M30 with 3.50 mm pitch and 60° thread angle.
• Right-hand cutting direction for standard threading operations.
• Four flutes provide efficient chip evacuation.
• Bright finish reduces friction and resists corrosion.
• Tolerance class ISO 2 (6H) for a precise fit.
