Evo Twist Drill Hss 0.25cm

EVO twist drill bit HSS with TRIcON shaft, type N, right-hand cutting, DIN 338, HSS, ground, TiAIN head coating Application area:
Precision drill for drilling steel up to 1000 N/mm² and cast steel (alloyed and non-alloyed), grey cast iron, malleable cast iron, spheroidal cast iron, sintered iron, nickel silver and graphite. Advice:
From 4.0 mm with TRIcON shaft Advantages:
118° EVO blade with cross-ground section
Drilling with pin-point accuracy - no centre punch; dimensional accuracy - precise drill holes; low feed and cutting forces - energy-saving operation Blue ring - for steel
Simple material assignment - no confusion; suitable for machine taps and countersinks TiAlN head coating
maximum service life - no built-up edges, greater surface hardness, improved thermal stability, dry machining possible; "NUR" coating on the area subjected to the greatest load - greater flexibility and more cost-effective TRIcON shaft, positive-fit transmission of forces
No movement in the drill chuck - optimal power transfer/no groove formation; no excessively deep clamping in the drill chuck - optimal elasticity; low energy expenditure when opening and closing the drill chuck - protects the drill chuck
