Kennametal 4149223 Solid Carbide Jobber Drill 5.80 Mm

Product Description

The KENNAMETAL 4149223 is a solid carbide jobber-length drill bit designed for high-performance hole-making in demanding materials. It features a 140-degree split point, a multilayer TiAlN coating, and a right-hand cutting direction with a regular spiral flute. The overall length is 3.228 inches (82 mm), with a flute length of 1.732 inches (44 mm) and a straight cylindrical shank diameter of 6 mm. Coolant-through capability supports chip evacuation and extended tool life in deep-hole applications. Built to DIN 6537K standards, this drill suits production environments where consistency and tool life are critical.

This drill is rated for use in steel, stainless steel, cast iron, aluminum, and other non-ferrous materials. The 5xD flute-to-diameter ratio and tapered web configuration make it well suited for CNC machining centers, drill presses, and production drilling fixtures in metalworking shops, maintenance facilities, and manufacturing environments. The straight shank fits standard collet chucks and drill chucks without adapters. It is a common choice for machinists and tool-and-die professionals working in tight-tolerance applications.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous and non-ferrous metals
• 140-degree point angle reduces thrust and improves self-centering on entry
• Multilayer TiAlN coating enhances heat resistance and extends cutting life
• Coolant-through design supports chip clearance in deep or blind holes
• DIN 6537K specification ensures dimensional consistency for interchangeable tooling programs
• Regular spiral flute with tapered web for balanced chip flow and core strength

Compatibility

Designed as an OEM-specification jobber drill for use in standard collet chucks, hydraulic chucks, and drill chucks accepting a 6 mm straight cylindrical shank across CNC and manual drilling equipment.

Installation Notes

Installation and use should be performed by qualified machinists or tooling technicians familiar with cutting tool setup and machine operation. Confirm spindle runout and chuck concentricity before use, as excessive runout accelerates carbide tool wear and increases breakage risk. Always follow machine manufacturer guidelines for feed rates and spindle speeds appropriate to the workpiece material. Coolant supply lines should be confirmed operational before engaging the coolant-through feature.
