9651 HSS. TiN tip has a polished body with a TiN coated cutting part which gives less friction, lower sectional forces, better resists wear and increases tool life and cutting speeds. With split point for accurate centring, reduces axial forces and gives a better hole tolerance. Standard drill for drilling steel and cast steel (alloyed and non-alloyed), cast iron and spheroidal graphite iron. Drill depth up to 5 times the diameter.
