Kennametal 2425290 Solid Carbide Jobber Drill 3.20mm Tialn

Product Description

The KENNAMETAL 2425290 is a solid carbide jobber-length drill bit designed for high-performance hole-making in demanding materials. Measuring 3.20 mm (0.1260 inches) in diameter with a 140-degree point angle, this drill delivers aggressive cutting entry and reduced thrust in hard and abrasive workpiece materials. The TiAlN coating provides heat resistance and extended tool life at elevated cutting speeds. A web-thinned, standard point geometry improves chip evacuation and centering accuracy. Overall length is 66.00 mm (2.5984 inches). This drill is intended for use by machinists and tool-and-die professionals working on production or maintenance operations.

This drill bit is suited for use in CNC machining centers, drill presses, and manual machine tools where precise, repeatable hole diameters are required. Primary workpiece materials include steel, stainless steel, cast iron, aluminum, and other non-ferrous metals. The coolant-through design makes it well-matched to high-volume drilling operations where internal coolant delivery is available, helping to manage chip load and thermal buildup in deep-hole applications. Typical applications include automotive, aerospace, and general metalworking environments requiring consistent tolerance control across high cycle counts.

Key Features

• TiAlN coating for elevated heat resistance and extended tool life in ferrous and stainless materials
• 140-degree point angle reduces entry thrust and improves self-centering on harder substrates
• Coolant-through construction supports internal coolant delivery for deep-hole and high-speed drilling
• Web-thinned parallel web geometry promotes efficient chip evacuation and lowers cutting forces
• Straight cylindrical shank (6 mm diameter) fits standard collet chucks and drill holders
• Conforms to DIN 6537L specification for consistent dimensional standards

Compatibility

Designed as a DIN 6537L-specification jobber drill for use in standard straight-shank collet chucks and drill holders accepting a 6 mm shank diameter, compatible with CNC and manual machine tool setups targeting steel, stainless steel, cast iron, aluminum, and non-ferrous workpiece materials.

Installation Notes

Installation and use should be performed by qualified machinists familiar with speeds, feeds, and toolholding requirements for solid carbide cutting tools. Ensure the machine spindle and toolholder are clean and properly torqued before seating the shank. Solid carbide tooling is brittle and should not be used in setups with excessive runout or unsupported overhang. Always confirm workpiece clamping is secure and that cutting parameters are appropriate for the workpiece material and machine rigidity before beginning the drilling cycle.
