Kennametal 5990988 Solid Carbide Jobber Drill 13.50 Mm

Product Description

The KENNAMETAL 5990988 is a solid carbide jobber-length drill designed for precision hole-making in aluminum and non-ferrous materials. It features a 135-degree split point, a 13.50 mm cutting diameter, and a bright uncoated finish suited for applications where coating adhesion or thermal buildup is not a concern. The 3-flat shank provides positive drive and resists slippage in the chuck. With a flute-to-diameter ratio of 5xD and coolant-through capability, this drill is built for production environments where chip evacuation and tool life consistency are priorities. Licensed machinists and CNC setup technicians are the primary installers of this tooling.

This drill is intended for use in aluminum, copper, brass, and other non-ferrous workpiece materials. The 2-flute regular spiral geometry promotes fast chip clearing in soft, gummy materials that can pack flutes in higher-flute-count drills. With a maximum drilling depth of 60.00 mm and an overall length of 124.00 mm, it fits standard machining centers, drill presses, and CNC turning centers equipped with a drill chuck or collet system accepting a 14 mm shank diameter.

Key Features

• Solid carbide construction for rigidity and wear resistance in non-ferrous cutting
• 135-degree point angle reduces thrust and improves self-centering on entry
• Coolant-through design flushes chips and reduces heat at the cutting edge
• 3-flat shank prevents rotational slippage under high torque loads
• Bright uncoated finish maintains sharp edge geometry without coating buildup
• 5xD flute-to-diameter ratio supports deeper holes without step drilling

Compatibility

Designed for use with machining centers, CNC mills, and drill presses accepting a 14 mm shank with a 3-flat drive configuration. Optimized for aluminum and non-ferrous workpiece materials as specified by the manufacturer.

Installation Notes

Installation should be performed by a qualified machinist or CNC technician. Confirm the machine spindle and toolholder are rated for the shank diameter and that set screws engage the flats securely before operation. Verify coolant-through pressure is within the machine specification before enabling through-tool flow. Do not exceed the maximum drilling depth of 60.00 mm in a single pass without an appropriate pecking cycle for chip management.
