Kennametal 6350479 0.4213 in Drill Bit Size, 2.7953 in Flute Length, 4.6457 in OAL, 2 Flutes, Carbide, Jobber Length Drill Bit

• 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.
• Spiral flutes are constructed with a higher flute angle to remove chips more easily.
• Solid carbide provides better rigidity than high speed steel.
