Tools & Gear Taps & Dies HSS Hand and Machine Taps

A33EC3376 3 x 0.5 MC Bottoming DIN 376 HSS-Co5 Tap - Goliath HSS-Co Bright Finish Reduced Long Series 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.
