Kennametal 4149196 Carbide Jobber Drill 4.10mm 140deg

Product Description

The KENNAMETAL 4149196 is a solid carbide jobber-length drill designed for high-performance hole-making in demanding materials. It features a 140-degree point angle optimized for fast penetration and reduced thrust in hard and abrasive workpiece materials. A multilayer TiAlN coating provides thermal resistance and extended tool life in dry or minimal-lubrication applications. The 4.10 mm cutting diameter pairs with a 6 mm straight-cylindrical shank, giving the tool added rigidity in standard drill chucks and collets. Overall length is 74.00 mm, with a two-flute regular spiral configuration and a tapered web for chip evacuation. Coolant-through capability supports high-speed deep-hole strategies where heat buildup is a concern.

This drill is suited for machining steel, stainless steel, cast iron, aluminum, and other non-ferrous materials in production and job-shop environments. The 5xD flute-to-diameter ratio and a maximum drilling depth of 29.00 mm make it appropriate for through-holes and moderate blind-hole work on CNC machining centers, drill presses, and automated lines. The right-hand cutting direction is standard for conventional spindle rotation. Machinists and tooling specialists working to DIN 6537K specifications will find this drill fits directly into those workflows.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• Multilayer TiAlN coating extends tool life under elevated cutting temperatures
• 140-degree point angle reduces thrust and improves centering on entry
• Coolant-through design supports high-speed drilling and chip flushing
• DIN 6537K specification compliance for consistent dimensional performance
• Tapered web configuration promotes efficient chip evacuation

Compatibility

Designed for use in standard straight-shank drill chucks and ER-series collet systems accepting a 6 mm shank diameter. Suitable for primary workpiece materials including steel, stainless steel, cast iron, aluminum, and non-ferrous alloys.

Installation Notes

Installation and tool changes should be performed with the machine spindle fully stopped and locked out per facility lockout/tagout procedures. Ensure the 6 mm shank is fully seated and the chuck or collet is tightened to the toolholder manufacturer's specification before cycling the spindle. Verify coolant-through passages are clear and supply pressure is appropriate for the holder style before enabling through-tool coolant. Inspect the cutting edges and coating condition before each use - carbide drills are brittle and should not be restarted in an interrupted or partially drilled hole without confirming edge integrity.
