      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.

      • KCMS15

        Composizione: Metallo duro a grana fine rivestito con monostrato PVD AlTiN con finitura superiore della superficie.

        Applicazione: Prima scelta per acciaio inossidabile e materiali resistenti al calore. Il rivestimento offre elevata durezza ed eccellente resistenza all'usura, oltre che proprietà migliorate alle alte temperature estendendone l'applicabilità anche a lavorazioni MQL dell'acciaio.
