UNC HSS Spiral Point Ground Taps


Precision HSS taps for machine tapping
Can be used for hand tapping without need of a lead tap.
Designed with a straight flute supplemented by an angular cutting point leaves the flutes clear of swarf for free coolant flow.
Blue steam tempered finish reduces friction and produces a fine finish thread
