IRWIN HSS TCT Tip Drill Bit 7.5mm x 109mm
Precision IRWIN HSS TCT drill bit for hardened steel, cast iron & alloys. 50 Rockwell C hardness, 7.5mm diameter.
The IRWIN HSS TCT Tip Drill Bit delivers exceptional drilling performance in hardened materials, making it ideal for professional and industrial applications. Featuring a Tungsten Carbide Tipped (TCT) design, this drill bit excels in drilling through hardened steel, cast iron, bronze alloys, and manganese alloyed steel with precision and durability. The C2 Carbide Tip is engineered to penetrate materials with a hardness of up to 50 Rockwell C, while its four-facetted grinding ensures low drilling pressure and perfect centring, enhancing accuracy and reducing operator fatigue.
Crafted from high-quality Chrome Vanadium Steel and hardened to 56 Rockwell C, the drill bit's robust construction guarantees a long service life, even under demanding conditions. For optimal performance and longevity, Irwin recommends using a 3-6% emulsion coolant during drilling operations. This not only enhances the bit's efficiency but also significantly extends its lifespan.
