Roll Tap Series Spiral Fluted Taps (for blind hole) MHRZ Roll Taps for Carbon Steels of Middle Hardness Spiral Fluted Taps (for through hole) Specification Coating 2D Spiral Pointed Taps (for through hole) Recommended Tapping Speeds depending on Materials Medium alloy steel and High alloy steel Tool steel heat treated steel IS P IS P IS P 10〜30 10〜30 10〜20 (m/min) (m/min) (m/min) Hand Taps For icon explanation, refer to P.50 Product features ●Due to Yamawa's proprietary design, the tapping torque decreases. ●With a combination of wear-resistant tool material and a unique coating, the tool's durability improves tremendously. Cemented Carbide Taps ●Consistent tapping of Heat treated steels（～ 35HRC）is ensured. ●Tapping with water soluble tapping fluid is possible.

Tapping fluid Water soluble oil Before the MHRZ, this material was thought to be difficult for thread forming. Thread Mills Application No more (Cutting tap) worries!! entangled chips Materials Tapping speed Slow Fast ～ 35HRC Dies Thermal refined MHRZ steels ～ 25HRC Alloy SCM steels ◆By adopting roll taps, the worries about the problems HP+RZ caused by chips are completely solved.
