Kennametal 4150787 Solid Carbide Jobber Drill 14mm 140 Deg

Product Description

The KENNAMETAL 4150787 is a solid carbide jobber-length drill bit designed for high-performance drilling in demanding industrial and machining applications. It features a 14 mm diameter, a 140-degree point angle, and a multilayer TiAlN coating that extends tool life by reducing heat buildup and wear at the cutting edge. The overall length is 124 mm (4.882 inches) with a 77 mm (3.031 inch) flute length, making it suitable for moderate-depth hole-making tasks. The straight cylindrical shank and right-hand spiral flute design provide consistent chip evacuation and straightforward setup in standard drill chucks or collet holders.

This drill is intended for use in CNC machining centers, drill presses, and manual lathes in production and job-shop environments. It is well suited for drilling steel, stainless steel, cast iron, aluminum, and other non-ferrous materials. The 5xD flute-to-diameter ratio supports applications where controlled chip flow and hole quality are priorities. It conforms to DIN 6537K specification, making it a direct fit for operations that require standardized tooling. Machinists and CNC operators in metalworking, fabrication, and precision machining will find this drill appropriate for general-purpose and production-grade hole-making.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive workpiece materials
• TiAlN multilayer coating reduces thermal wear and extends cutting tool life
• 140-degree point angle reduces thrust force and improves centering on entry
• Right-hand cut with regular spiral flute geometry for efficient chip evacuation
• Straight cylindrical shank compatible with standard drill chucks and collet systems
• Conforms to DIN 6537K specification for standardized tooling interchangeability

Compatibility

Designed as a DIN 6537K-compliant jobber drill for use in machining operations involving steel, stainless steel, cast iron, aluminum, and non-ferrous materials. Compatible with any tool holder or chuck accepting a 14 mm straight cylindrical shank.

Installation Notes

Installation and tool changes should be performed by a qualified machinist or CNC operator with the machine fully powered down and spindle locked. Ensure the shank is fully seated and the tool holder is properly torqued before operation. Carbide tooling is brittle and should not be used in setups with excessive runout or unsupported workpieces, as lateral shock loads can cause chipping or fracture. Verify spindle speed and feed rate are appropriate for the workpiece material and hole depth before starting the cut.
