RUKO HGB DIN 2181 HSS 60° Metric Fine Thread Hand Tap M20 x 1.00 mm

Cutting precise metric fine threads by hand in through or blind holes demands a tap that holds its edge and follows the DIN 2181 standard. The RUKO HGB hand tap set provides a ground-thread, high-speed steel tool with a 60° thread angle for M20 x 1.00 mm threads, ensuring clean, accurate results in general-purpose steels and non-ferrous metals.

Who is it for

Machinists, metalworkers, and maintenance technicians who need reliable hand tapping for repair, prototyping, or small-batch production. Ideal for workshops where metric fine threads are required and a square drive tap is preferred for secure tool holding.
