Kennametal 4150668 Solid Carbide Jobber Drill 5.10mm

Product Description

The KENNAMETAL 4150668 is a solid carbide jobber-length drill bit designed for high-performance metal cutting applications. Built to DIN 6537K specification, it features a 140-degree split point, a multilayer TiAlN coating for extended tool life, and a right-hand spiral flute geometry. The drill measures 5.10 mm (0.2008 inches) in diameter with an overall length of 82.00 mm (3.23 inches) and a flute length of 44.00 mm (1.73 inches). The straight cylindrical shank measures 6 mm (0.25 inches) in diameter. This bit is intended for use by machinists and tool-and-die professionals working in production environments.

This drill is suited for cutting steel, stainless steel, cast iron, aluminum, and non-ferrous materials. The 5xD flute-to-diameter ratio and tapered web configuration support chip evacuation and point stability in through-hole and blind-hole drilling operations. It is a strong fit for CNC machining centers, manual drill presses, and bench-top setups where tight diameter tolerances are required. The diameter tolerance is held to -0.0005 to 0.0000 inches, making it appropriate for precision-fit hole applications.

Key Features

• Solid carbide construction per DIN 6537K for rigidity and wear resistance
• 140-degree point angle reduces entry force and walking on hardened surfaces
• Multilayer TiAlN coating extends tool life in ferrous and stainless applications
• Right-hand, regular spiral flute promotes reliable chip evacuation
• Tapered web configuration improves point strength and centering
• Diameter tolerance of -0.0005 to 0.0000 inches supports precision bore sizing

Compatibility

Designed as a DIN 6537K-conforming jobber drill for use in standard straight-shank drill chucks and collet holders accepting a 6 mm (0.25 inch) shank. Suitable for steel, stainless steel, cast iron, aluminum, and non-ferrous workpiece materials as specified by the manufacturer.

Installation Notes

Installation and use should be performed by qualified machinists or tool operators. Ensure the drill chuck or collet is rated for the shank diameter and that the spindle is at a full stop before tool changes. Verify workpiece clamping is secure before initiating a cut. Do not exceed the maximum drilling depth of 35.00 mm (1.38 inches) as rated for this flute geometry.
