Kennametal 4149344 Solid Carbide Jobber Drill 14.50 Mm

Product Description

The KENNAMETAL 4149344 is a solid carbide jobber-length drill designed for high-performance hole-making in demanding production environments. It features a 14.50 mm cutting diameter, a 140-degree split point, and a multilayer TiAlN coating that extends tool life at elevated cutting temperatures. The two-flute, right-hand spiral configuration promotes efficient chip evacuation, and the integrated coolant-through capability delivers cutting fluid directly to the cutting edge. This drill is sized for use in CNC machining centers, drill presses, and automated production equipment where dimensional accuracy and long run life are required.

This jobber drill is suited for drilling steel, stainless steel, cast iron, aluminum, and non-ferrous materials in both light and heavy manufacturing applications. The straight cylindrical shank accepts standard collet chucks and drill chucks without adapters. The 5xD flute-to-diameter ratio supports drilling to a maximum depth of 63.00 mm, making it appropriate for through-hole and moderate blind-hole applications in production machining. Machinists and CNC operators working in job shops, OEM production lines, and maintenance machining environments are the primary users of this tool.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive workpiece materials
• Multilayer TiAlN coating supports higher cutting speeds and resists heat buildup
• 140-degree point angle reduces thrust force and improves self-centering on entry
• Coolant-through design delivers fluid directly to the cutting zone for heat control and chip flushing
• Right-hand, regular spiral flute promotes reliable chip evacuation in deep-hole drilling
• Conforms to DIN 6537K specification for consistent dimensional standards

Compatibility

Designed as an OEM-style replacement or direct-selection solid carbide jobber drill for CNC machining centers and drill presses accepting straight cylindrical shank tooling in the 12.50 mm to 15.00 mm drill diameter range. Compatible with standard collet chucks and drill chucks sized for a 16 mm shank diameter.

Installation Notes

Installation and operation of this drill should be performed by a qualified machinist or CNC operator familiar with carbide tooling. Before mounting, confirm the machine spindle and chuck are clean and free of debris to prevent runout that can chip carbide cutting edges. Enable coolant-through supply before initiating the cut, and verify that coolant pressure is appropriate for the machine setup. Carbide tooling is brittle and should never be used in machines with excessive spindle runout or in applications requiring hand-feeding without controlled feed rate.
