Irwin Hss Tct Drill Bit 11mm Pack of 1

This 11mm Irwin HSS TCT drill bit provides robust drilling capability for larger holes in hardened materials. The 11mm diameter is ideal for substantial mounting applications, larger structural fasteners, and industrial drilling operations where you need reliable penetration through hardened steel, cast iron, and bronze alloys. Equipped with a tungsten carbide tip, this drill bit is engineered to handle materials up to 50 Rockwell C hardness with precision and reliability. The four-facetted ground tip design ensures perfect centring, which is crucial at this larger diameter for maintaining accuracy and preventing tool deflection under higher drilling forces. The reduced drilling pressure characteristic makes operation more efficient and controlled. The Chrome Vanadium Steel body, hardened to 56 Rockwell C, offers the strength and rigidity essential for larger diameter drilling in demanding materials. This 11mm bit is designed for use with stationary drilling machines and delivers best results when operated with a 3-6% coolant emulsion. Following Irwin's coolant recommendation will maximise cutting performance and substantially extend the service life of the drill bit.
