Irwin Hss Tct Drill Bit 13mm Pack of 1

This 13mm Irwin HSS TCT drill bit provides robust drilling performance for substantial holes in hardened materials. The 13mm diameter is ideal for heavy-duty industrial applications, larger structural fasteners, and mounting systems where you need reliable penetration through hardened steel, cast iron, and bronze alloys. The tungsten carbide tip is specifically engineered to handle materials up to 50 Rockwell C hardness, providing consistent performance even in the most challenging drilling conditions. The four-facetted ground tip design ensures perfect centring, which becomes increasingly critical at larger diameters for maintaining accuracy and preventing tool deflection. The reduced drilling pressure characteristic makes operation more efficient and controlled, particularly important when working with larger hole sizes. The Chrome Vanadium Steel body, hardened to 56 Rockwell C, offers exceptional strength and rigidity. Designed for stationary machine use, this 13mm drill bit performs best when operated with a 3-6% coolant emulsion as recommended by Irwin. The coolant is essential for maintaining optimal cutting efficiency and significantly extending the service life of the drill bit.
