Taps
Which tap steel is right for your job?
Pick a family to narrow SKUs.
Atlas Cutting Tools manufactures our taps right here in the USA using only domestic materials, covering both standard HSS taps and High Performance spiral flute and spiral point CNC-style taps built for modern high-speed tapping equipment. Sizes include Screw & Fractional, Metric, and Pipe/Pulley Thread Forming taps, plus Straight Spiral Flute styles for improved chip evacuation in blind holes.
Spiral point taps push chips forward and ahead of the tap, ideal for through-holes, while spiral flute taps pull chips back and up, better suited to blind holes. Whichever style your job calls for, our taps are backed by consistent USA manufacturing quality and same-day shipping on in-stock sizes.
