Irwin HSS TCT Drill Bit

This 9mm Irwin HSS TCT drill bit delivers robust drilling performance for larger holes in hardened materials. The 9mm diameter is ideal for substantial mounting applications, larger fasteners, and structural work where you need to drill through hardened steel, cast iron, or bronze alloys.

The tungsten carbide tip is specifically engineered to handle materials up to 50 Rockwell C hardness, providing reliable penetration even in the most demanding conditions. The four-facetted ground tip design ensures perfect centring, which becomes increasingly important at this larger diameter where any misalignment would be more pronounced. The reduced drilling pressure characteristic also makes operation more efficient and controlled. The Chrome Vanadium Steel body, hardened to 56 Rockwell C, offers the strength and rigidity needed for larger diameter drilling operations.

Designed for stationary machine use, this 9mm 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.
