RUKO HGB-sarja DIN 352 HSS 60° 7/16" UNC käsikierretappisarja

Hand tap set for cutting UNC threads with 7/16 inch diameter and 14 TPI. The set includes three taps: taper, second, and bottoming, made of high-speed steel (HSS) to DIN 352 with a 60° thread angle. Suitable for through and blind holes in materials up to 900 N/mm² tensile strength.

Advantages

HSS construction provides durability and wear resistance. The three-piece set allows progressive threading: taper tap for starting, second tap for intermediate, and bottoming tap for threads close to the bottom of blind holes. Bright finish reduces friction and aids chip flow.
