Buying Guide

Tap material matters

Choose HSS for longer life and harder alloys, or carbon steel for basic plumbing threads and lower cost

Match thread form and size

Confirm NPT vs metric and the exact size (for example 1-1/2"-11.5 NPT or M18x1.5) before buying to avoid misfit

Set vs single tap

Buy a multi-piece NPT set for versatility on plumbing jobs and a single specialty tap for a specific fitting or repair

Hand threader vs machine tap

Select a hand-threader style for manual threading and larger diameter pipe, or drill/tap kits for powered use and pilot holes

Look for included drill bits

Kits that include matched drill bits simplify hole preparation and ensure correct pilot sizes for corresponding taps
