The Tap HSS 12x1.75mm & Drill 10.3mm 2-Piece Set includes both a high-speed steel (HSS) tap and a corresponding drill bit. The tap is designed to create internal threads with a 12mm diameter and a 1.75mm thread pitch, ideal for applications that require 12mm threaded fasteners. The included 10.3mm drill bit is the correct size to pre-drill holes before tapping, ensuring optimal thread formation. Both pieces are made from high-quality HSS material, offering durability, heat resistance, and wear resistance for use in metals, plastics, or other materials. This set is perfect for industrial, automotive, or mechanical applications.
