Description:

Metric 3-step HSS M20 DIN 352 hand tap.
Designed for creating M20 threads.
Made of HSS high-speed steel, these taps are highly durable and strong, making them ideal for threading metal.
They meet the German DIN 352 standard, which specifies the dimensions and parameters of hand taps, including thread form, helix angle, shank diameter, and working length.
They have a tolerance class of 6H (ISO 2), ensuring they meet all requirements for nominal metric thread diameter deviation.

they are industrial quality.

Threading is done in 3 stages:

Stage 1 - Pre-cutting the thread in the hole
Stage 2 - Countersinking the thread in the hole
