Hand Taps

Wiseman HSS metric hand taps, M2.5 up to M24. A standard three-tap set works through taper lead (starts the thread, easiest entry), second lead (works the thread deeper), and bottom lead (cuts to the base of a blind hole) — run them in that order for a full-depth thread in a hole that doesn't go all the way through.

Available in standard tolerance (+0.001"), and Hand Tap tolerance (+0.002", a looser fit for easier hand tapping). Also stocked: Machine Nut taps (bottom lead, for tapping nuts) and Left Hand taps for reverse threads.

If the hole has already stripped, a hand tap won't bring it back — running a standard tap through a damaged thread only removes more material. That repair needs helicoil taps and a wire insert, which puts a hardened steel thread back into the softer parent material.

All held in UK stock. Order before 4.30pm and it ships same day.
