RUKO HGB Set DIN 352 HSS 60° M12 x 1,75 mm käsikierretappisetti, 3-osainen

Hand tap set for cutting metric ISO threads with a nominal diameter of 12 mm and a pitch of 1.75 mm. The set contains three taps: taper tap, second tap, and bottoming tap, enabling full thread production in through and blind holes. Manufactured from high-speed steel (HSS) to DIN 352 with a 60° thread flank angle and tolerance class ISO 2 (6H).

Advantages

HSS provides high wear resistance and long tool life. The three-piece set allows progressive cutting: taper tap for starting, second tap for intermediate, and bottoming tap for threads close to the hole bottom. Bright finish reduces friction and improves chip flow.

Suitable for

• Unalloyed and alloyed steels
