Machine taps for metric coarse thread, extra long
The extra long version reaches threads that sit deep inside a part: in through holes, behind stepped bores and anywhere the standard length falls short. Machine taps cut the thread in a single pass and run in a drilling machine, a machining centre or a tapping attachment.
VÖLKEL offers 50 versions to DIN 371 and DIN 376, in HSSE, from M 3 x 0.5 to M 12 x 1.75. Lead forms B and C cover through holes and blind holes.
