Kennametal 4149497 Solid Carbide Jobber Drill 10.50 Mm

Product Description

The KENNAMETAL 4149497 is a solid carbide jobber-length drill engineered for high-performance hole-making in demanding production environments. It features a 10.50 mm (0.4134 inch) diameter, a 140-degree point angle for improved centering and reduced thrust, and a multilayer TiAlN coating that extends tool life in abrasive and high-temperature cutting conditions. The two-flute right-hand spiral design promotes efficient chip evacuation, while the tapered web configuration adds rigidity at the cutting edge. Coolant-through capability makes this drill well suited to CNC machining centers running high-feed cycles on difficult materials. Trade machinists and tool-and-die professionals select this bit for consistent diameter tolerance held to -0.0007 to 0.0000 inches.

This drill is designed for cutting steel, stainless steel, cast iron, aluminum, and other non-ferrous materials in both job-shop and production settings. The whistle notch shank seats securely in compatible milling machine or machining center toolholders, resisting pullout under aggressive feeds. At a 5xD flute-to-diameter ratio and a maximum drilling depth of 56.00 mm (2.2047 inches), it handles through-holes and blind bores in medium to thick workpiece stock. It conforms to DIN 6537K specification, making it a recognized standard for CNC drill applications across manufacturing, fabrication, and maintenance-repair-overhaul environments.

Key Features

• Solid carbide construction provides rigidity and wear resistance beyond high-speed steel alternatives
• Multilayer TiAlN coating reduces heat buildup and extends tool life in ferrous and stainless applications
• 140-degree point angle improves self-centering and lowers axial cutting force
• Coolant-through design delivers cutting fluid directly to the cutting edge for deep-hole performance
• Whistle notch shank prevents rotational slippage in compatible toolholders
• Conforms to DIN 6537K for standardized fitment in CNC tooling systems

Compatibility

Compatible with toolholders accepting a 12 mm (0.4219 inch) shank diameter with a whistle notch drive feature. Suitable for use in CNC machining centers, drill presses, and milling machines configured for solid carbide tooling. Intended for workpiece materials including steel, stainless steel, cast iron, aluminum, and non-ferrous alloys per the manufacturer specification.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician familiar with CNC toolholder setup procedures. Ensure the machine spindle is fully stopped and the tool magazine or holder is de-energized before inserting or removing the drill. Verify toolholder bore cleanliness and confirm the whistle notch is properly engaged before securing the retention screw to manufacturer-specified procedure. Do not exceed the maximum drilling depth of 56.00 mm without confirming adequate coolant flow through the spindle.
