300F.3xD Solid carbide twist drills, CRALINIT-coated, drilling depth 3xD, drill angle 140°, with lubrication holes, drill diameter from 3 to 20mm
(Incl. Tax: €46.36)
Solid carbide (HM) twist drills with CRALINIT coating and coolant holes, engineered for drilling up to 3xD with improved cooling and chip evacuation. h7 cutting diameter and h6 shank for secure clamping and good concentricity on chip-removal machine tools. The CRALINIT coating improves wear resistance, lowers friction and helps prevent material build-up, delivering longer tool life and better surface finish. 140° point, suitable for common steels, cast iron, aluminum and stainless steel (HRC <52).
Solid carbide (HM) twist drills with CRALINIT coating and coolant holes, designed for drilling up to 3xD on lathes, mills, drilling machines and CNC machining centers. The 140° point supports stable entry and efficient chip evacuation; h7 cutting diameter and h6 shank tolerances improve concentric running and secure clamping. The coolant holes deliver fluid directly to the cutting zone, improving cooling and chip removal while reducing heat and increasing process consistency. The CRALINIT coating helps reduce friction and built-up edge, increasing wear resistance and tool life. Configurable diameter range Ø3–Ø20 mm, 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.
