RUKO HGB Set 2-Piece DIN 2181 Metric Fine Hand Tap Set M30 x 1.0

Cutting precise M30 x 1.0 metric fine threads by hand in tough materials demands taps that stay sharp and aligned. This 2-piece HSS-G hand tap set solves that with ground flutes and a DIN 2181 design built for clean, accurate threads in steel, cast iron, and non-ferrous metals.

Who is it for

Machinists, metalworkers, and maintenance technicians who need reliable hand tapping for through holes and blind holes in unalloyed or low-alloy steels up to 800 N/mm², malleable cast iron, and non-ferrous metals.

Main features

• Set includes taper tap (No. 1) and plug tap (No. 2) for progressive thread cutting.
• Metric fine thread M30 x 1.0 with 60° profile angle, ISO 2 (6H) tolerance class.
• Made from HSS-G (high-speed steel, ground) for durability and clean cutting edges.
• Bright uncoated finish reduces chip adhesion in general-purpose work.
• Right-hand cutting direction, 4-5 flutes for efficient chip evacuation.
