Did you know? M6 = 5 mm

Tapping drill size is nominal diameter minus pitch. For M6 at 1 mm pitch that is 5 mm, in practice the most common mistake made when cutting threads.

Threading Tool Accessories

Völkel threading tools

Threading tool accessories cover the holders used to guide and drive taps and dies. Tap wrenches to DIN 1814 take the square shank of a hand tap, die holders to DIN 225 (DIN EN 22568) guide round dies, and there are holders to DIN 223 for sizes M 3 to M 12 as well as versions to DIN 377. The decisive factors are the mounting size, the clamping range and the material of the holder, with zinc die casting common for workshop use and steel for higher torque. The category holds 204 articles, 203 of them from Völkel, plus a miniature threading set from Bernstein for M 1.0 to M 2.5.
