Kennametal 4150724 Carbide Jobber Drill 9mm 140 Deg

Product Description

The KENNAMETAL 4150724 is a solid carbide jobber-length drill designed for high-performance hole-making in demanding materials. It features a 9.00 mm diameter, a 140-degree point angle, and a multilayer TiAlN coating that extends tool life in abrasive and heat-intensive applications. The overall length is 103.00 mm (4.0551 inches), with a flute length of 61.00 mm (2.4016 inches) and a straight cylindrical shank diameter of 10 mm (0.4063 inches). The right-hand, regular spiral flute geometry promotes efficient chip evacuation. This drill is installed by machinists and tool-room professionals in CNC and manual drilling operations requiring tight tolerances and consistent hole quality.

This jobber drill is suited for use in steel, stainless steel, cast iron, aluminum, and non-ferrous materials. The 5xD flute-to-diameter ratio and tapered web configuration make it effective in production environments where consistent chip flow and point stability are required. It conforms to DIN 6537K specifications, making it appropriate for applications where standardized tooling geometry is specified. Typical use cases include general-purpose through-hole and blind-hole drilling in job shops, manufacturing facilities, and maintenance operations.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive workpiece materials
• Multilayer TiAlN coating provides thermal and oxidation resistance at elevated cutting speeds
• 140-degree point angle reduces thrust and improves self-centering on entry
• Regular spiral flute geometry with tapered web supports consistent chip evacuation
• Straight cylindrical shank compatible with standard drill chucks and collet holders
• Conforms to DIN 6537K specification for standardized geometry and dimensional consistency

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC machining centers, drill presses, and manual machines using straight-shank tool holders in the 9.00 mm to 10.00 mm range. Primary workpiece materials include steel, stainless steel, cast iron, aluminum, and non-ferrous alloys.

Installation Notes

Installation is performed by machinists or tooling technicians. Ensure the machine spindle is fully powered down and locked out before changing tooling. Seat the straight shank fully and evenly in the chuck or collet holder and confirm runout is within acceptable limits before beginning a cut. Do not use this drill in applications requiring coolant-through delivery, as this model does not support internal coolant channels.
