Kennametal 1199380 Solid Carbide Jobber Drill 6.60 Mm

Product Description

The KENNAMETAL 1199380 is a solid carbide jobber-length drill designed for precision hole-making in demanding materials. It measures 6.60 mm in diameter with a 130-degree point angle and a web-thinned, tapered web configuration that reduces entry force and improves chip evacuation. The three-flute, regular spiral design provides a strong cutting geometry suited for cast iron, aluminum and non-ferrous metals, and high-temperature alloys. Overall length is 91.00 mm (3.5827 inches) with a flute length of 53.00 mm (2.0866 inches). The bright, uncoated finish is suitable for applications where coating adhesion to the workpiece is a concern. Machinists and tool-room professionals use this drill in CNC machining centers and manual drilling operations.

This drill is appropriate for production and job-shop environments where tight hole tolerances and clean entry are required. Primary workpiece materials include cast iron, aluminum and non-ferrous metals, and high-temperature alloys. The straight cylindrical shank with an 8 mm shank diameter fits standard drill chucks and collet holders. Conforming to DIN 6537L, this drill is suited for use in industries such as aerospace, automotive, and general metalworking where carbide tooling is preferred over high-speed steel for extended tool life at higher cutting speeds.

Key Features

• Solid carbide construction in material grade K10 for hardness and wear resistance in abrasive materials
• 130-degree point angle with web-thinned, tapered web for reduced thrust and improved chip flow
• Three-flute regular spiral design increases core strength and supports higher feed rates
• Bright/uncoated finish maintains sharp cutting edges without coating buildup
• Straight cylindrical shank compatible with standard drill chucks and collet holders
• Conforms to DIN 6537L specification for consistent dimensional accuracy

Compatibility

Designed as a DIN 6537L-specification jobber drill for use in CNC machining centers and manual drilling equipment accepting straight-shank tooling with an 8 mm shank diameter. Suitable for machining cast iron, aluminum and non-ferrous metals, and high-temperature alloys.

Installation Notes

Installation of this drill should be performed by a qualified machinist following standard tooling change procedures. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before inserting the shank. Secure the shank to the specified clamping torque for the chuck or collet system in use. Verify runout with a dial indicator before commencing production cuts to maintain diameter tolerance.
