EX-AL-SFT is a spiral tap for aluminum
Because of the particularity of aluminum (soft and sticky knife, not easy to cause chip taps of blocked chips wear broken), aluminum taps flutes its relatively ordinary spiral screw is reduced to two, and was discharged in the continuous deepening and widening processing cutting aluminum material cutting effect is good. Because the rightward rotation worm groove 35 degree cutting can be discharged out from the hole, the cutting speed can be compared with the straight groove screw speed 30%-50%, because of its relatively common screw flutes deeper and wider so not easy blocked chips, the tap is not easy to break. Secondly, aluminum special wire tapping effective tooth length reduced to ordinary tap 1/3, deep hole machining is also very effective.
Applicable materials: aluminum, aluminum alloy, aluminum alloy castings, etc..
