Machine taps with white ring
In this programme the white ring marks the steam-tempered HSSE version. The oxide layer holds lubricant and resists welding to the workpiece. The coloured ring on the shank identifies the version at a glance, without reading the marking — useful when several variants of the same size sit side by side on the shelf.
VÖLKEL offers 151 versions to DIN 371, DIN 374, DIN 376 and DIN 5156, in HSSE, from M 3 x 0.5 to M 42 x 4.5, plus UNC 1/4 x 20 to UNC 1/2 x 13 and UNF 1/4 x 28 to UNF 1/2 x 20. Lead forms B and C cover through holes and blind holes, part of the range is steam tempered (VAP).
