Kennametal 1591924 Solid Carbide Jobber Drill 0.2280 in

Product Description

The KENNAMETAL 1591924 is a solid carbide jobber-length drill designed for high-performance hole-making in demanding materials. Built to DIN 6537L specification, it features a 130-degree split point, three-flute regular spiral geometry, and a TiAlN coating for heat resistance and extended tool life. The drill measures 0.2280 inches (wire size No. 1) in diameter with a 0.2500-inch straight cylindrical shank and an overall length of 3.2300 inches. Web thinning reduces thrust and improves chip evacuation at entry. This tool is intended for use by machining professionals in production and job-shop environments.

This drill is suited for cutting cast iron, aluminum and non-ferrous metals, and high-temperature alloys. The three-flute configuration supports higher feed rates compared to standard two-flute designs, making it well-suited for short-cycle, high-volume drilling operations in both vertical machining centers and drill presses. Maximum drilling depth is 1.3700 inches, with a flute length of 1.6900 inches. The 0.2500-inch shank fits standard collet chucks and drill chucks commonly found in CNC and manual machine setups.

Key Features

• Solid carbide construction in material grade K10 for rigidity and wear resistance
• TiAlN coating improves heat resistance and extends tool life in abrasive and high-temp materials
• 130-degree point angle with web thinning reduces entry thrust and improves centering
• Three-flute regular spiral geometry supports higher feed rates and improved chip flow
• Parallel web configuration maintains consistent core strength throughout flute length
• Right-hand cutting, no coolant-through; external coolant or flood coolant recommended

Compatibility

Designed as an OEM-specification solid carbide jobber drill per DIN 6537L for use in machining applications involving cast iron, aluminum and non-ferrous materials, and high-temperature alloys. Compatible with standard 0.2500-inch collet chucks and drill chucks.

Installation Notes

This tool is installed and operated by machinists and CNC technicians. Secure the straight shank in a properly sized collet chuck or keyless drill chuck and verify runout before cutting. Power down and de-energize the machine spindle before tool changes. Do not use this drill without confirming spindle speed and feed rate are appropriate for the workpiece material and drill diameter.
