Taps

Taps

Made in USA since 1992

Which tap steel is right for your job?

High Performance
High Performance Powder-metal high speed steel Finer grain — more wear resistance and stability Best for CNC tapping centers, high-volume production
HSS
HSS Conventional high speed steel Widest range of styles and thread types Best for General threading, hand and machine tapping

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.
