300.3xD Solid carbide twist drills CRALINIT 3xD, point angle 140°, no coolant holes, tip diameter from 2 to 20mm
(Incl. Tax: €30.50)
Solid carbide (HM) twist drills with CRALINIT coating for precise drilling up to 3xD without coolant holes. h7 cutting diameter and h6 shank for reliable clamping and concentricity. The CRALINIT coating improves wear resistance, reduces friction and helps prevent material build-up, enhancing tool life and finish.
Solid carbide (HM) twist drills with CRALINIT coating designed for drilling up to 3xD on lathes, mills, drilling machines and CNC machining centers. The 140° point supports stable entry and chip evacuation; h7 cutting diameter and h6 shank tolerances improve concentric running and secure clamping. The CRALINIT coating helps reduce friction and built-up edge, increasing wear resistance and tool life. Configurable diameter range Ø2–Ø20 mm covers micro-drilling and standard production drilling. Suitable for common steels, cast iron, aluminum and stainless steel up to HRC <52. Industries: machine shops, automotive, aerospace, mold & die, metal fabrication, industrial maintenance and serial production.
