Kennametal 1913568 Solid Carbide Jobber Drill 4.20 Mm

Product Description

The KENNAMETAL 1913568 is a solid carbide jobber-length drill designed for high-performance hole-making in ferrous and non-ferrous materials. It measures 4.20 mm in diameter with an overall length of 74.00 mm (2.9134 inches) and a flute length of 36.00 mm (1.4173 inches). The 140-degree split point reduces walking and decreases thrust force at entry. A TiAlN coating provides thermal resistance and extends tool life in demanding production environments. The straight cylindrical shank seats in standard drill chucks without additional toolholding hardware. This drill is sized to DIN 6537L and suited for machinists, tool-and-die makers, and CNC operators running moderate to high-volume drilling cycles.

This drill is built for cutting steel, stainless steel, cast iron, aluminum, and other non-ferrous materials. It fits production and job-shop environments where consistent hole quality and tool life are required. The web-thinned geometry reduces centerline pressure and improves chip evacuation in deeper passes. With a maximum drilling depth of 29.00 mm (1.1417 inches) and coolant-through capability, it suits applications where thermal management at the cutting edge is critical. The right-hand spiral flute direction is compatible with standard spindle rotation on vertical machining centers, knee mills, and bench drill presses.

Key Features

• TiAlN coating for heat resistance and extended tool life in steel and stainless applications
• 140-degree point angle reduces drill walk and entry thrust
• Coolant-through construction delivers cutting fluid directly to the tip
• Web-thinned, parallel-web geometry improves chip flow and reduces centerline load
• Diameter tolerance of +0.004 to +0.016 mm for consistent hole sizing
• DIN 6537L specification ensures dimensional conformance for tooling interchangeability

Compatibility

Designed as a DIN 6537L-specification jobber drill compatible with standard straight-shank drill chucks and collet systems accepting a 6 mm shank diameter. Suitable for machining steel, stainless steel, cast iron, aluminum, and non-ferrous workpiece materials.

Installation Notes

Installation and use should be performed by qualified machinists or CNC operators familiar with cutting tool setup. Before mounting, verify that the spindle, chuck, or collet is clean, undamaged, and rated for the shank diameter. Secure the shank fully within the holding device to the recommended engagement depth before starting the spindle. Always confirm coolant lines are primed and directed correctly when using the coolant-through feature, and follow applicable machine safety lockout procedures before making any tooling changes.
