HSS TCT Drill Bit 10mm Pack 1

This 10mm Irwin HSS TCT drill bit is a workshop staple for drilling larger holes in hardened materials. The 10mm diameter is one of the most frequently used sizes in engineering and fabrication, ideal for substantial bolt holes, mounting applications, and structural connections in challenging materials. Featuring a tungsten carbide tip, this drill bit is engineered to penetrate hardened steel, cast iron, bronze alloys, and manganese alloyed steel up to 50 Rockwell C hardness. The four-facetted ground tip provides precise centring from initial contact, which is essential at 10mm diameter for maintaining accuracy under the higher drilling forces involved. The reduced drilling pressure characteristic ensures smoother, more controlled operation. The Chrome Vanadium Steel body, hardened to 56 Rockwell C, delivers the strength and rigidity required for larger diameter drilling in hard materials. Designed for use with stationary drilling machines, this 10mm bit performs optimally when operated with a 3-6% coolant emulsion. Following Irwin's coolant recommendation significantly extends tool life and maintains consistent cutting performance throughout the drill bit's service life.
