Kennametal 2404438 Solid Carbide Drill Bit 6.30 Mm

Product Description

The KENNAMETAL 2404438 is a screw machine length drill bit engineered for high-performance drilling in demanding production environments. Built from solid carbide grade KC7315 and coated with TiAlN, this bit handles cast iron and steel with consistent results. It features a 140-degree point angle with web thinning for reduced thrust and improved chip evacuation. At 6.30 mm in diameter with a 79.00 mm overall length, the compact screw machine geometry suits applications where rigidity and hole accuracy are critical. Licensed machinists, tool and die technicians, and CNC operators are the primary users of this type of tooling.

This drill bit is designed for screw machine, CNC lathe, and machining center applications where short flute-to-diameter ratios improve rigidity and reduce deflection. The straight cylindrical shank at 8.00 mm diameter seats in standard drill chucks and collet systems. Primary workpiece materials include cast iron and steel. With a maximum drilling depth of 24.00 mm and a flute length of 34.00 mm, this bit is suited for through-hole and blind-hole operations in production-rate environments where tool life and dimensional consistency are priorities. The DIN 6537K specification governs its geometry.

Key Features

• Solid carbide KC7315 grade for extended tool life in ferrous materials
• TiAlN coating improves heat resistance and wear performance in dry or semi-dry cutting
• 140-degree point angle with web thinning reduces entry thrust and improves self-centering
• Screw machine length geometry increases rigidity and minimizes deflection
• Regular spiral flute with parallel web configuration for consistent chip flow
• Manufactured to DIN 6537K specification for repeatable dimensional accuracy

Compatibility

Designed for use in CNC machining centers, screw machines, and drill presses equipped with standard collet or drill chuck toolholding accepting an 8.00 mm straight cylindrical shank. Suitable for drilling cast iron and steel workpiece materials. Part of the KENNAMETAL Dynapoint High Performance series B966A, covering the 5.00 mm to 6.50 mm diameter range.

Installation Notes

Install and remove carbide drill bits with the spindle fully stopped and machine power locked out per facility safety procedures. Seat the straight shank fully in the collet or chuck before tightening to the toolholder manufacturer's specified clamping procedure. Inspect the cutting edges and TiAlN coating for chipping or wear before each use, as carbide is brittle and sensitive to interrupted cuts if the setup has excessive runout. Do not use this bit beyond its rated maximum drilling depth of 24.00 mm without retracting and clearing chips.
