Description

Features

Back To Top
    • Y-TECH drills with through coolant for difficult-to-machine materials.
    • Material-/application-specific SC drill engineered to drill stainless steel, high-temp alloys, and difficult-to-machine materials.
    • Y-TECH technology with uneven flute-to-flute angle creates unbalanced forces by design to avoid chipping on margin lands.
    • Three-margin lands reduce pendulum motion by directing forces towards third margin, which results in superior hole accuracy (cylindricity, constant diameter, and hole straightness), also in steel.
    • KCMS15 grade is a Monolayer PVD AlTiN coated fine grain carbide with superior surface finish. First choice for stainless steel, high-temperature resistant materials. The coating offers high hardness and excellent wear resistance as well as enhanced high-temperature properties increasing its applicability also to MQL machining of steel.
