Kennametal 4150647 Solid Carbide Jobber Drill 3.80 Mm

Product Description

The KENNAMETAL 4150647 is a solid carbide jobber-length drill bit designed for high-performance drilling in demanding industrial and trade applications. Built to DIN 6537K specification, this drill features a 3.80 mm diameter, a 140-degree point angle, and a multilayer TiAlN coating that extends tool life in abrasive and high-heat cutting environments. The two-flute, right-hand spiral geometry delivers efficient chip evacuation and stable cutting action. With an overall length of 74.00 mm (2.913 inches) and a flute length of 36.00 mm (1.417 inches), it suits standard jobber-depth drilling tasks on CNC machining centers and manual drill presses alike.

This drill bit is suited for cutting steel, stainless steel, cast iron, aluminum, and other non-ferrous materials. A straight cylindrical shank with a 6 mm diameter (0.984 inches) allows direct mounting in standard collet chucks and drill chucks. The 5xD flute-to-diameter ratio and tapered web configuration support accurate hole entry and maintain rigidity through the cut. Typical users include machining technicians, toolroom professionals, and industrial maintenance trades working in fabrication, manufacturing, and repair environments.

Key Features

• Solid carbide construction provides rigidity and wear resistance in hard and abrasive workpiece materials
• Multilayer TiAlN coating reduces heat buildup and extends tool life in steel and stainless steel applications
• 140-degree point angle improves self-centering and reduces thrust force on entry
• DIN 6537K specification ensures dimensional consistency and interchangeability
• Tapered web and regular spiral flute design promote stable chip flow and reduce recutting
• Straight cylindrical shank fits standard collet and keyless chuck systems without adapters

Compatibility

Designed as an OEM-specification replacement and standard jobber drill for use in CNC machining centers, drill presses, and multi-spindle equipment that accept straight-shank tooling in the 3.00 mm to 4.00 mm diameter range per DIN standards.

Installation Notes

Installation is performed by qualified machining technicians or toolroom personnel. Secure the shank fully within the collet or chuck to the recommended grip length before operation, and verify runout with a dial indicator when tolerance-critical hole quality is required. Always power down and lock out the spindle drive before changing tooling. Do not exceed the maximum drilling depth of 29.00 mm (1.142 inches) without retracting to clear chips, particularly in blind-hole applications.
