Description

20 x 2.5 MC Bottoming DIN 376 HSS-Co5 Tap – Goliath
HSS-Co Bright Finish Reduced Shank Metric Coarse Hand and Machine Bottoming Tap.
HSS Cobalt Long Series Tap made to DIN 376 standard.
Reduced shank taps have a smaller shank diameter than full-diameter taps.
Reduced shank taps are designed for through hole applications in materials with high tensile strength.
Goliath HSS taps provide a high hardness to toughness ratio, compressive and tensile strength, good abrasion resistance and resistance to micro-chipping, ensuring a long tool life.
Bottoming Taps have a lead of two threads and are used to ensure minimum thread run-out when tapping to the bottom of a blind hole.
Bottoming Taps are typically preceded by the use of a Taper or Intermediate Tap.
Manufactured from HSS-Co5.
