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.
