Kennametal 4149197 Jobber Drill 4.20mm Solid Carbide

Product Description

The KENNAMETAL 4149197 is a solid carbide jobber drill designed for high-performance hole-making in demanding materials. It features a 4.20 mm (0.1654 inch) cutting diameter and a 140-degree point angle optimized for fast, accurate penetration with minimal walking. The multilayer TiAlN coating extends tool life in abrasive and heat-generating applications. With an overall length of 74.00 mm (2.9134 inches) and a 36.00 mm (1.4173 inch) flute length, this drill is built for production drilling where consistency and repeatability matter. It is installed by machinists and CNC operators in manufacturing and fabrication environments.

This drill is suited for drilling into steel, stainless steel, cast iron, aluminum, and other non-ferrous materials in both light and heavy production settings. The 5xD flute-to-diameter ratio supports chip evacuation in moderate-depth holes. Coolant-through capability makes it a practical choice for higher-speed operations where thermal management is critical. The straight cylindrical shank with a 6 mm (0.3750 inch) diameter fits standard drill chucks and collet holders commonly found in CNC machining centers and drill presses.

Key Features

• 4.20 mm (0.1654 inch) solid carbide construction for rigidity and wear resistance
• 140-degree point angle reduces thrust and improves self-centering on entry
• Multilayer TiAlN coating for heat resistance in steel and stainless steel applications
• Coolant-through design supports high-speed production drilling
• Right-hand, regular spiral flute for consistent chip evacuation
• Conforms to DIN 6537K specification for dimensional reliability

Compatibility

Designed as a DIN 6537K-compliant jobber drill suitable for use in CNC machining centers, drill presses, and multi-spindle setups equipped with standard straight-shank toolholders or collet chucks accepting a 6 mm shank.

Installation Notes

This drill is intended for installation and use by qualified machinists or CNC technicians. Power down and de-energize the machine spindle before installing or changing the drill. Ensure the shank is fully seated and the collet or chuck is properly torqued before operation. Verify coolant lines are clear and flow is confirmed prior to initiating a drilling cycle when using the through-coolant feature.
