Kennametal 4150276 Carbide Drill Bit 9.70mm 140 Deg

Product Description

The KENNAMETAL 4150276 is a screw machine length (stub length) solid carbide drill bit designed for high-productivity drilling in metalworking and machining applications. Configured in the Series B041A-CPG, it features a 9.70 mm cutting diameter, a 140-degree standard point angle, and a multilayer TiAlN coating for extended tool life in abrasive and high-temperature cutting conditions. The overall length is 89.00 mm (3.5039 inches) with a 47.00 mm (1.8504 inch) flute length. Right-hand cutting direction and a regular spiral flute geometry provide efficient chip evacuation. This bit is installed by machinists and toolroom technicians in production drilling operations.

The 4150276 is suited for stub-length drilling applications where rigidity and minimal deflection are priorities, such as CNC machining centers, drill presses, and automated production environments. The straight cylindrical shank measures 10.00 mm (0.3937 inches) in diameter, allowing direct mounting in standard collets and drill chucks. Maximum drilling depth is 35.00 mm (1.3780 inches). The tapered web configuration and 3xD flute-to-diameter ratio support controlled chip flow during interrupted and continuous cuts in ferrous and non-ferrous materials.

Key Features

• Solid carbide construction provides rigidity and wear resistance versus high-speed steel alternatives
• Multilayer TiAlN coating extends tool life in high-temperature drilling applications
• 140-degree point angle reduces thrust force and improves self-centering on entry
• Straight cylindrical shank compatible with standard collets and Weldon-style holders
• Tapered web design supports chip evacuation and reduces cutting forces at depth
• Conforms to DIN 6537K specification for dimensional consistency

Compatibility

Designed as an OEM-style replacement and production cutting tool for use in standard drill chucks and collet systems accepting a 10.00 mm straight shank, within the Series B041A-CPG product family and the drill bit size range of 9.50 mm to 11.00 mm.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is powered down and locked out before changing tooling. Secure the shank fully within the collet or chuck to the manufacturer-recommended engagement depth and verify runout with a dial indicator before production use. Do not exceed the maximum drilling depth of 35.00 mm in a single pass without evaluating chip clearance.
