Kennametal 2649380 Screw Machine Drill Bit 15/32 in

Product Description

The KENNAMETAL 2649380 is a screw machine length drill bit designed for high-performance drilling in demanding metalworking applications. Built from solid carbide and coated with a multilayer TiAlN finish, this bit delivers extended tool life at elevated cutting speeds. It measures 15/32 inches (0.4688 inches) in diameter with a 140-degree split point and an overall length of 4.0157 inches. The two-flute, right-hand spiral configuration evacuates chips efficiently, while the web-thinned parallel web reduces thrust force at entry. Licensed machinists, tool-and-die shops, and production drilling operations are the primary users of this grade of tooling.

This drill bit is suited for production-volume drilling in cast iron and steel workpieces where tight tolerances and surface finish matter. The screw machine length profile keeps the bit rigid and minimizes deflection in short-reach setups on CNC machining centers, drill presses, and screw machines. The straight cylindrical shank, 0.4724 inches in diameter, seats directly into standard chucks or collet holders without adapters. Coolant-through capability supports high-speed drilling cycles where chip clearance and heat management are critical factors.

Key Features

• Solid carbide construction rated for high-performance cutting in cast iron and steel
• Multilayer TiAlN coating for heat resistance and extended tool life at high surface footage
• 140-degree split point reduces walking and lowers entry thrust
• Web-thinned parallel web design for reduced axial force
• Coolant-through design supports high-cycle production drilling
• Conforms to DIN 6537K specification for dimensional consistency

Compatibility

Designed for use in CNC machining centers, drill presses, and screw machines accepting a 0.4724-inch straight cylindrical shank. Primary workpiece materials are cast iron and steel. Part of the Kennametal Series B976 screw machine length program.

Installation Notes

Installation and tool changes should be performed with the machine powered down and in a locked-out state per applicable safety procedures. Seat the shank fully in the chuck or collet holder and verify runout before cycling the spindle. When running coolant-through, confirm the machine spindle and toolholder are configured for internal coolant delivery. Follow the tool manufacturer's recommended speeds and feeds for the specific workpiece material and cutting condition.
