Características e benefícios

YPC Beyond drills with through coolant for iron materials.

Material-specific SC drill specifically engineered to deliver best-in-class hole quality and longest tool life in cast iron, ductile iron, CGI, and ADI.

Y-TECH™ technology with uneven flute-to-flute angle creates unbalanced forces by design avoid chipping on margin lands.

Three-margin lands reduce pendulum motion by directing forces towards third margin for superior hole accuracy (cylindricity, constant diameter, hole straightness).

Corner chamfer avoids breakout when drilling through holes in gray iron.

KCK10™ Beyond grade contains multiple layers of PVD coating offering outstanding wear resistance for the drilling of cast irons.
