Kennametal 2658236 Solid Carbide Jobber Drill 5/8 in 140 Deg

Product Description

The KENNAMETAL 2658236 is a solid carbide jobber-length drill bit designed for high-performance hole-making in demanding materials. It measures 0.625 inches in diameter with a 140-degree split point and a TiAlN (titanium aluminum nitride) coating that extends tool life at elevated cutting temperatures. The overall length is 5.2362 inches with a flute length of 3.2677 inches. Coolant-through capability directs cutting fluid directly to the cutting edge, improving chip evacuation and thermal control during deep drilling. This drill is suited for production machining environments where tool longevity and hole accuracy are critical.

This drill is built for cutting steel, stainless steel, cast iron, aluminum, and other non-ferrous materials. The right-hand spiral flute geometry and web-thinned point reduce thrust force at entry, making it well-suited for CNC machining centers and drill presses running tight-tolerance production work. The straight cylindrical shank fits standard collet chucks and drill chucks across common machine spindle sizes. It conforms to DIN 6537L specification, which defines jobber drill geometry for precision industrial tooling applications.

Key Features

• TiAlN coating provides heat and wear resistance for extended tool life in ferrous and non-ferrous materials
• 140-degree point angle reduces thrust and improves self-centering on entry
• Coolant-through design delivers fluid directly to the cutting zone for chip control and thermal management
• Web-thinned parallel web lowers cutting resistance and improves hole entry performance
• Conforms to DIN 6537L specification for consistent jobber-length geometry
• Right-hand cutting direction with regular spiral flute for efficient chip evacuation

Compatibility

Designed for use in CNC machining centers, drill presses, and other machine tools accepting a 0.6299-inch straight cylindrical shank. Rated for drilling steel, stainless steel, cast iron, aluminum, and non-ferrous materials within the 0.5000 to 0.6500 inch drill bit size range.

Installation Notes

Installation and tool changes should be performed by qualified machinists or tooling technicians with the machine fully powered down and locked out per OSHA lockout/tagout procedures. Secure the shank firmly in a collet chuck or drill chuck rated for the shank diameter before beginning any cutting operation. Verify coolant-through supply lines are connected and flow is confirmed before drilling to prevent premature tool wear. Do not use this drill as a manual hand-drill bit; it is designed exclusively for machine spindle use.
