Kennametal 3640746 Jobber Length Drill Bit, 4.50 mm (0.1772) Dia, 140 deg, Solid Carbide, AlTiN Finish, 74.00 mm

Features:

• Jobber Length Drill Bit: 4.50 mm (0.1772) Dia, 140 deg, Solid Carbide
• AlTiN Finish, 74.00 mm OAL, Right Hand Cut, Regular Spiral Flute, Straight Shank
• Composition: Monolayer PVD AlTiN coated fine-grain carbide with superior surface finish.
• Y-TECH drill with through coolant for difficult-to-machine materials.
• Material-/application-specific SC drill engineered to drill stainless steel, high-temp alloys, and difficult-to-machine materials.
• Y-TECH technology with uneven flute-to-flute angle creates unbalanced forces by design to avoid chipping on margin lands.
• Three-margin lands reduce pendulum motion by directing forces towards third margin, which results in superior hole accuracy (cylindricity, constant diameter, and hole straightness), also in steel.
• 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.

Application:

• First choice for stainless steel and 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.
