Kennametal 4149332 Solid Carbide Jobber Drill 13.50mm

Product Description

The KENNAMETAL 4149332 is a solid carbide jobber-length drill designed for high-performance hole-making in demanding metal-cutting applications. The drill features a 13.50 mm cutting diameter, a 140-degree point angle for self-centering entry, and a multilayer TiAlN coating that extends tool life under elevated cutting temperatures. Overall length is 124.00 mm with a 77.00 mm flute length, delivering a 5xD flute-to-diameter ratio suited to deeper drilling cycles. Two right-hand spiral flutes provide efficient chip evacuation. Coolant-through capability allows internal delivery of cutting fluid directly to the cutting edge, supporting higher feed rates and longer tool life in production environments. This drill is installed and operated by machinists and tool-room professionals in CNC and manual drilling applications.

The 4149332 is intended for use in steel, stainless steel, cast iron, aluminum, and other non-ferrous workpiece materials. Its straight cylindrical shank with a 14 mm shank diameter seats in standard drill chucks or collet holders. The 5xD flute ratio supports drilling to a maximum depth of 60.00 mm. This drill conforms to DIN 6537K geometry, making it a direct fit for shops working to DIN-standard tooling programs. Typical applications include production drilling, jig-and-fixture work, and precision hole-making where dimensional consistency and surface finish are required.

Key Features

• 13.50 mm cutting diameter with a tolerance of -0.0007 to 0.0000 inches for precise, on-size holes
• 140-degree standard point angle for positive self-centering and reduced thrust force
• Multilayer TiAlN coating for heat resistance and extended tool life in ferrous materials
• Coolant-through design delivers cutting fluid directly to the cutting zone
• Two regular spiral flutes with tapered web for efficient chip removal
• Conforms to DIN 6537K specification for standardized geometry and interchangeability

Compatibility

Designed for use in standard drill chucks, hydraulic chucks, and collet holders accepting a 14 mm straight cylindrical shank. Compatible workpiece materials include steel, stainless steel, cast iron, aluminum, and non-ferrous alloys per DIN 6537K specification.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's setup procedures. Ensure the spindle is fully stopped and the machine is in a safe state before loading or removing tooling. Verify the shank is fully seated and the holder is properly torqued before initiating a cut. Coolant-through setups require that the machine's internal coolant supply pressure and flow rate are within the tool holder and spindle specifications before drilling begins.
