Yamawa Z-PRO Hybrid Value Spiral Tap for Steel (for Unified Threads)

The unique groove shape and cutting angle improve chip removal.
The heel cut performance has been improved to accurately cut chips deep inside the screw and eliminate any remaining chips.
Since no chips remain, chipping problems at the cutting edge, which tend to occur when reversing, are greatly reduced.
The screw section has a special shape that leaves a few complete threads and then removes half of the remaining threads, which increases the effectiveness of preventing chipping of the complete thread section.
For machining blind holes.
Work material: For low carbon steel, medium carbon steel, high carbon steel, alloy steel, tempered steel (25-35HRC), stainless steel, and cast steel.
