Kennametal 1913621 Taper Length Drill Bit 6.5 Mm

Product Description

The KENNAMETAL 1913621 is a taper length drill bit built for high-performance hole-making in ferrous materials. Manufactured from solid carbide and coated with TiAlN, it delivers extended tool life at elevated cutting speeds compared to high-speed steel alternatives. The bit features a 132-degree drill point angle optimized for reduced thrust and accurate entry on hard workpieces. A web-thinned, tapered web configuration improves chip evacuation and lowers cutting forces. At 6.5 mm in diameter with a 105 mm overall length, this drill is suited for production machining environments where consistency and tool longevity are priorities. A coolant-through design supports internal coolant delivery to the cutting zone.

This drill bit is designed for cutting cast iron and steel. It fits into machining centers, CNC drilling machines, and manual drill presses equipped with a straight shank collet or chuck. The straight-cylindrical shank measures 8 mm in diameter, making it compatible with standard ER collet systems and equivalent toolholding. The spiral flute geometry promotes consistent chip clearing during through-hole and blind-hole drilling operations in both production and job shop environments.

Key Features

• Solid carbide construction for rigidity and heat resistance in ferrous material applications
• TiAlN coating extends tool life at high cutting temperatures
• 132-degree point angle reduces entry thrust and improves hole location accuracy
• Coolant-through channels deliver coolant directly to the cutting edge
• Web-thinned, tapered web reduces cutting forces and aids chip evacuation
• Right-hand spiral flute for standard clockwise cutting operations

Compatibility

Rated for use in cast iron and steel. Straight-cylindrical shank is compatible with standard ER collets, drill chucks, and equivalent toolholding systems accepting an 8 mm shank diameter. Conforms to DIN 6537K specification.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and machine power off or locked out per applicable OSHA lockout/tagout procedures. Ensure the collet or chuck is clean and undamaged before seating the shank. Verify coolant-through compatibility with the machine spindle before use if internal coolant delivery is required. Do not exceed the recommended maximum drilling depth of 57 mm for this tool.
