Kennametal 4150791 Solid Carbide Jobber Drill 14.30 Mm

Product Description

The KENNAMETAL 4150791 is a solid carbide jobber-length drill designed for high-performance hole-making in steel, stainless steel, cast iron, aluminum, and other non-ferrous materials. It measures 14.30 mm (0.5630 inches) in diameter with a 140-degree standard point angle and a multilayer TiAlN coating that extends tool life at elevated cutting temperatures. Overall length is 133.00 mm (5.2362 inches), with a 2-flute right-hand spiral flute configuration that promotes chip evacuation. The straight cylindrical shank measures 16 mm (0.6094 inches) in diameter. Machinists and tool-and-die professionals rely on this drill for demanding production environments where dimensional accuracy and tool durability are critical.

This drill is suited for use in CNC machining centers, drill presses, and manual machines where a straight-shank carbide jobber drill is required. It carries a 5xD flute-to-diameter ratio, supporting drilling depths up to 63.00 mm (2.4803 inches). Primary workpiece materials include steel, stainless steel, cast iron, aluminum, and non-ferrous alloys. It conforms to DIN 6537K specification, making it a recognized standard-compliant tool for industrial and toolroom applications. Coolant-through capability is not included in this configuration.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• Multilayer TiAlN coating improves heat resistance and extends tool life in ferrous cutting
• 140-degree standard point angle reduces thrust and improves self-centering on entry
• Right-hand, regular spiral flute geometry promotes consistent chip evacuation
• DIN 6537K compliant straight cylindrical shank for broad machine compatibility
• Tapered web configuration maintains core strength while reducing cutting resistance

Compatibility

Compatible with machine spindles and drill chucks accepting a 16 mm (0.6094 inch) straight cylindrical shank. Suitable for use in steel, stainless steel, cast iron, aluminum, and non-ferrous workpiece materials per DIN 6537K specification.

Installation Notes

This drill is installed and operated by machinists, CNC operators, and tool-and-die technicians. Before installation, ensure the machine spindle is fully powered down and locked out per applicable safety procedures. Verify chuck or collet bore size matches the 16 mm shank diameter before tightening. Solid carbide tooling is brittle compared to HSS - avoid lateral loading, interrupted cuts beyond the tool rating, or re-chucking with worn or damaged holders, as these conditions can cause fracture.
