Kennametal 2658235 Solid Carbide Jobber Drill 9/16 Inch

Product Description

The KENNAMETAL 2658235 is a solid carbide jobber-length drill bit designed for high-performance drilling in demanding production environments. It features a TiAlN coating that extends tool life by resisting heat and wear at elevated cutting speeds. The 140-degree point angle promotes accurate self-centering and reduces thrust force on entry, making it well suited for harder workpiece materials. With a right-hand spiral flute and web-thinned point geometry, the 2658235 evacuates chips efficiently and maintains consistent hole quality throughout the cut. Machinists and tool room technicians working in job shops, manufacturing cells, and maintenance operations will find this drill a reliable choice for high-accuracy through-hole and blind-hole applications.

The 2658235 is built for cutting steel, stainless steel, cast iron, aluminum, and other non-ferrous materials. Its coolant-through design allows internal coolant delivery directly to the cutting edge, which is critical when drilling deep holes or running high-cycle production programs in CNC machining centers and drill presses. The straight-cylindrical shank fits standard ER collet chucks, drill chucks, and hydraulic toolholders commonly used in vertical and horizontal machining centers. This drill is manufactured to DIN 6537L specification, ensuring dimensional consistency for shops with tight process controls.

Key Features

• Solid carbide construction for rigidity and long tool life in hard materials
• TiAlN coating resists heat and abrasive wear at high cutting speeds
• 140-degree standard point angle for accurate self-centering on entry
• Coolant-through design delivers cutting fluid directly to the drill tip
• Web-thinned, parallel-web geometry improves chip evacuation and reduces thrust
• Manufactured to DIN 6537L specification for consistent dimensional accuracy

Compatibility

Suitable for use in CNC machining centers, drill presses, and other machine tools equipped with collet chucks or drill chucks accepting a 0.6299-inch straight-cylindrical shank. Rated for drilling steel, stainless steel, cast iron, aluminum, and non-ferrous materials per the manufacturer specifications.

Installation Notes

This drill bit is installed by a machinist or tool room technician into a compatible toolholder; verify shank seating and runout before beginning a production run. Ensure the machine spindle is fully stopped and the tool changer or quill is in a safe position before inserting or removing the drill. Use the correct collet size for the 0.6299-inch shank to prevent slippage and maintain concentricity. When utilizing the coolant-through feature, confirm that the toolholder and spindle support internal coolant delivery at the required pressure for the application.
