Kennametal 4148913 Screw Machine Drill Bit, 3.40 mm (0.1339) Dia, 140 deg, Solid Carbide, TiN Finish, 62.00 mm

Features:

• Screw Machine Drill Bit: 3.40 mm (0.1339) Dia, 140 deg, Solid Carbide
• TiN Finish, 62.00 mm OAL, Right Hand Cut, 2 Flute, Regular Spiral Flute, Whistle Notch Shank, Coolant Through, GOdrill B051F-CPG
• Composition: Multilayered PVD TiN-TiAlN coated fine-grain carbide with a TiN top layer for better wear identification.
• General purpose SC drill for a wide range of materials.
• Marginless design for reduced friction and heat - thus longer tool life.
• Optimized gashing design for microdrilling ensures free flow of chips in the center of the drill.
• Uninterrupted straight cutting lip allows no starting point for wear and enables even distribution of cutting forces for longer tool life in all materials and less chipping on cutting edge.
• KC7325 grade contains a double coating for broad-band applications, and a TiN top layer serves as a wear indicator for easier monitoring of small drills, which can be difficult to see.
