Metric Machine Tap Set

-- Steady & Reliable Manufacturer --

Product Overview

This is a boxed, multi-size set of metric machine taps covering the most commonly used sizes for CNC and drill-press tapping, so a shop or maintenance department can stock one case rather than ordering each size separately. It combines spiral point and/or spiral flute geometries depending on the set configuration selected.

We supply this set to CNC and general machine shops setting up a tap crib, and to tooling distributors who resell boxed sets to smaller shops that want broad size coverage without managing individual tap purchases.
