Spiral Point Machine Tap
WTI spiral point taps are for use in through holes
It will tap precise holes in a single pass at very high peripheral speeds
A Spiral Point is ground into the lead threads at an angle to the tap axis. This produces a tap with initial left hand flutes that have a progressive cutting rake towards the point of the tap.
The swarf produced is pushed ahead of the tap and falls free as it emerges through the hole.
Eliminating hazards caused by chips accumulating in the flutes during cutting.
