Kennametal 4149216 Solid Carbide Jobber Drill 5.40mm

Product Description

The KENNAMETAL 4149216 is a solid carbide jobber-length drill designed for high-performance hole-making in demanding materials. It features a 140-degree point angle for reduced thrust and improved centering on hard workpieces, a multilayer TiAlN coating for heat resistance and extended tool life, and a right-hand spiral flute geometry following the DIN 6537K specification. The drill measures 5.40 mm in diameter with an overall length of 82.00 mm and a flute length of 44.00 mm. Coolant-through capability supports chip evacuation and thermal management at depth. Machining professionals and tool-and-die shops install this drill on CNC machining centers and drill presses for precision production work.

This drill is suited for cutting steel, stainless steel, cast iron, aluminum, and other non-ferrous materials. Its 5xD flute-to-diameter ratio makes it appropriate for moderate-depth drilling applications where chip control and hole quality are priorities. The straight cylindrical shank with a 6 mm shank diameter fits standard drill chucks and collet systems. It is a practical choice for job shops, production machining environments, and maintenance operations that require consistent hole tolerances in metalworking applications.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous and non-ferrous materials
• 140-degree point angle reduces axial thrust and improves self-centering
• Multilayer TiAlN coating provides thermal and oxidation resistance at elevated cutting speeds
• Coolant-through design aids chip removal and controls heat at the cutting edge
• DIN 6537K specification ensures dimensional consistency and interchangeability
• Tapered web configuration and regular spiral flute geometry support stable chip flow

Compatibility

Designed as a high-performance replacement jobber drill for CNC machining centers and drill presses using standard straight-shank toolholders or collet chucks accommodating a 6 mm shank diameter.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Secure the straight shank in a properly sized collet or drill chuck and verify runout before committing to a production run. Always disengage spindle power and confirm the machine is in a safe, locked-out state before changing tooling. Consult the machine manufacturer and applicable shop safety standards for appropriate cutting parameters when working with the coolant-through feature.
