Features and benefits



  • SGL drills with through coolant for stainless steel and high-temperature alloys.

  • By combining unique Kennametal features such as the all new SGL-Point-Geometry with a patented gashing, an unique Flute Design and a best in class coating into one tool, the B21*SGL drill is the ultimate high volume production tool.

  • All new SGL point geometry with improved web thinning and patented gashing which migrate in a straight cutting edge enables high cutting parameters (feeds), improves hole quality and creates controlled chips which leads to a reliable performance.

  • 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.

  • The highly polished surface ensures superior chip evacuation even when low-pressure coolant is applied.

  • Ideal point angle and tolerance make the B21_SGL series the preffered pilot drill for B27_SGL series Solid Carbide deep Hole Drills.

Grades

  • KCMS15

    Composition : Carbure à grain fin avec revêtement AlTiN PVD monocouche à l'excellent état de surface.

    Application : Premier choix pour les aciers inoxydables et les alliages réfractaires. Le revêtement possède une grande ténacité et une excellente résistance à l'usure avec une très bonne résistance aux températures élevées, permettant à cette nuance de trouver son emploi dans l'usinage MQL de l'acier.
