Osg 8672240 Solid Carbide Jobber Drill 2.40 Mm 140 Deg

Product Description

The OSG 8672240 is a solid carbide jobber-length drill bit designed for high-performance drilling in ferrous materials. It measures 2.40 mm in diameter (0.0945 inches) with a 140-degree split point and an overall length of 66.00 mm. The EgiAs coating reduces friction and extends tool life in demanding applications. The X-thinned web geometry improves penetration and reduces thrust force at entry. This drill is suited for machinists, tool-and-die technicians, and CNC operators working with precision components that require consistent hole quality at small diameters.

The OSG 8672240 is intended for use in steel, alloy steel, and cast iron workpieces. It performs well in blind hole, cross hole, standard drilling, and self-centering applications. The 5xD flute-to-diameter ratio makes it appropriate for moderate-depth holes. It is commonly used in production machining environments, job shops, and maintenance operations where small-diameter, tight-tolerance holes are required in hard ferrous materials.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• EgiAs coating reduces heat buildup and extends cutting life
• 140-degree X-thinned point improves self-centering and reduces exit burr
• Right-hand spiral flute with regular helix for efficient chip evacuation
• Straight-cylindrical shank with 4.00 mm shank diameter fits standard collets and drill chucks
• Diameter tolerance of +0 to -0.014 mm supports close-tolerance hole requirements

Compatibility

Designed as an OEM-style replacement or direct-use drill bit within the OSG Series 6310 product family, suited for CNC machining centers, drill presses, and manual machines using straight-shank toolholders accepting a 4.00 mm shank.

Installation Notes

This drill bit is installed by a machinist or CNC technician into a compatible collet, chuck, or toolholder. Ensure the machine spindle is fully stopped and locked out before changing tooling. Use appropriate cutting fluid or coolant at the entry point when drilling steel or cast iron to manage heat, as this drill does not support through-coolant. Confirm runout of the toolholder before starting a production run to protect the carbide from premature chipping.
