ACHSP| Spiral Fluted Tap for Aluminum Casting | YAMAWA

Features

• Direct tapping of cored holes without drilling first, results in reducing the manufacturing time.
• Made from an ultrafine grain carbide alloy combining the hardness and toughness.
• The shank diameter is the same as the major diameter of the tap which improves rigidity and makes the ACHSP more
  resistant to deflection and the cutting side pressure caused from misalignment. (Maximum displacement of core hole: M6 · M8 within 0.3 mm, M 10 within 0.5 mm) 
• A thin film coating offers improvements in wear resistance and a reduction of cutting edge chipping.

Reduction of machining time
Correcting misaligned cast pilot holes is unnecessary shortening the tapping process time!

 

 

■Recommendation
Internal coolant supply is recommended to prevent the tapped holes from being blocked by the ejected chips.
