Spiral Point Tap 1/4 -28 HSS MPN:EP2321302-UNF1/4
Spiral Point Tap 1/4 -28 HSS
The Spiral Point Tap 1/4 -28 HSS is designed for precision machining tasks that require thread cutting operations on various metals like mild steel, aluminum, brass or stainless steel using cobalt high-speed steel construction offering superior wear resistance. It has a three flute design which enables fast chip removal while preventing tool clogging and a plug chamfer for creating clean threads after every turn of the screw. Its versatility across industries such as automotive or aerospace makes it an economical solution when accuracy in threading operations is essential.
The THL coating on these taps protects them from wear and provides better chip formation than TiN and TiCN coatings. THL-coated taps are suitable for threading high-speed steel, cast iron, and aluminum alloys, and they can be used with or without coolant.
