SPIRAL FLUTED TAPS FOR FORGED PARTS IN THE HEAVY METALWORKING INDUSTRY

Recommended Tapping Speeds depending on Materials

ความเร็วรอบจะขึ้น อยู่กับวัสดุที่ใช้ในการต๊าป

● YAMAWA has designed a flute shape and cutting edge angle to improve the chip ejection properties.
● A heel grind on the rear threads has improved the performance of the tap and eliminated the materials chip residue in the threads that is caused on reversal by the tap’s end threads.
● With no chips left in the threads, the tapping operation is less likely to chip the flutes or threads of the tap during the tap’s reversal.
● There are several full threads after the cutting chamfer and a special heel grind to the balance of the threads to reduce their full thread height, thereby reducing any chance of chipping the flutes.
