Osg 8672540 Solid Carbide Jobber Drill 5.40 Mm 140 Deg

Product Description

The OSG 8672540 is a solid carbide jobber-length drill bit designed for high-performance drilling in ferrous materials. It features a 5.40 mm diameter, a 140-degree R-thinned point, and an EgiAs coating that reduces friction and extends tool life in demanding applications. The two-flute spiral design with a regular helix promotes efficient chip evacuation. With an overall length of 82.00 mm and a flute length of 44.00 mm, this drill delivers a 5xD flute-to-diameter ratio suited for production environments where consistency and hole quality matter. It is installed and operated by machinists and tool-and-die professionals working in metalworking and fabrication settings.

This drill bit is engineered for use in steel, alloy steel, and cast iron workpieces. Typical applications include blind hole drilling, cross hole operations, standard through drilling, and self-centering entry points where a thinned web reduces thrust force. The straight-cylindrical shank measures 6.00 mm in diameter for secure chuck or collet retention. Its high-performance classification makes it appropriate for CNC machining centers, drill presses, and automated production lines running at elevated feed and speed parameters.

Key Features

• 5.40 mm diameter with a tolerance of +0 to -0.018 mm for precise hole sizing
• 140-degree R-thinned point with tapered web configuration for reduced entry thrust
• EgiAs coating for extended wear resistance in steel and cast iron
• Solid carbide construction for rigidity and heat resistance versus high-speed steel alternatives
• 6.00 mm straight-cylindrical shank compatible with standard chucks and collets
• Rated for blind hole, cross hole, drilling, and self-centering tool applications

Compatibility

Designed for use on steel, alloy steel, and cast iron workpieces. Part of OSG Series 6310, covering drill bit diameters in the 5.00 mm to 6.00 mm range (0.2000 to 0.2500 decimal inch equivalent).

Installation Notes

Installation and operation should be performed by qualified machinists or tooling technicians familiar with carbide tooling. Ensure the machine spindle and chuck or collet are clean and properly seated before securing the straight shank. Carbide is brittle compared to high-speed steel — avoid side loading, interrupted cuts without appropriate feed compensation, or dropping the tool on hard surfaces. Follow machine manufacturer guidelines for speed and feed rates appropriate to the workpiece material and hole depth.
