Special taper <strong>shank</strong> <strong>drills</strong> <strong>with</strong> two coolant<br />
channels to deliver the coolant under<br />
pressure directly to the cutting edges.<br />
Maximum coolant circulation and continuous<br />
chip flush-out ensure long service<br />
life and permit efficient drilling of deep<br />
holes especially in the vertical and horizontal<br />
position.<br />
For machining of cast steel alloyed and<br />
non-alloyed up to approx. 900 N/mm 2 ,<br />
malleable cast iron, aluminium alloys<br />
short-chipping, brass, electrolytic copper,<br />
bronze, gun metal.<br />

Web taper: none<br />
Flute form: wide flutes<br />
Tolerance on Ø: h8<br />
