Kennametal 1199351 Solid Carbide Jobber Drill 4.80 Mm

Product Description

The KENNAMETAL 1199351 is a solid carbide jobber-length drill bit designed for precision hole-making in demanding materials. Ground to a 130-degree split point with web thinning, it reduces thrust and improves centering without a pilot hole. The three-flute spiral configuration promotes faster chip evacuation compared to standard two-flute designs, making it well suited for production drilling cycles where throughput and hole quality both matter. At 4.80 mm in diameter with an overall length of 82.00 mm, it fits standard straight-shank toolholders and drill chucks across CNC machining centers and manual drill presses alike. Licensed machinists and CNC operators installing this tool should verify runout and collet concentricity before production runs.

This drill is rated for use in cast iron, aluminum and non-ferrous materials, and high-temperature alloys. Its K10 carbide grade and bright uncoated finish make it a practical choice for applications where coating adhesion to non-ferrous materials is a concern, or where re-sharpening without stripping a coating is preferred. Typical applications include aerospace component drilling, die and mold work, and high-volume production machining of cast iron housings. The DIN 6537L specification ensures dimensional conformity for shops sourcing to European or international drawing standards.

Key Features

• Solid carbide construction in K10 grade for rigidity and wear resistance in hard and abrasive materials
• 130-degree point angle with web thinning reduces entry thrust and improves self-centering
• Three-flute design promotes faster chip evacuation versus standard two-flute jobber drills
• Bright uncoated finish compatible with non-ferrous and high-temp alloy applications
• Straight cylindrical shank fits standard drill chucks and ER-style collet holders
• Manufactured to DIN 6537L specification for consistent dimensional tolerances

Compatibility

Designed as a straight-shank jobber drill conforming to DIN 6537L, this bit is compatible with standard drill chucks and ER collet systems sized for a 6 mm shank diameter across CNC machining centers, drill presses, and manual machine tools.

Installation Notes

Installation and use should be performed by qualified machinists familiar with solid carbide tooling requirements. Always power down and lock out the spindle before changing tooling. Carbide drills are brittle compared to HSS and require rigid setups with minimal runout to prevent chipping or breakage. Do not use this drill in applications requiring coolant-through passages, as this tool is not designed for internal coolant delivery.
