Osg 8693390 Solid Carbide Jobber Drill 13.90 Mm 140 Deg

Product Description

The OSG 8693390 is a solid carbide jobber-length drill bit designed for high-performance drilling in demanding metalworking applications. It features a 13.90 mm diameter with a 140-degree point angle and an R-thinned web for improved self-centering and reduced thrust. The EgiAs coating enhances wear resistance and heat dissipation, making it suitable for sustained use in production environments. With an overall length of 176.00 mm and a flute length of 112.00 mm, this drill is built for depth-to-diameter ratios up to 5xD. It is typically installed by machinists and toolroom technicians in CNC and manual drilling operations.

This drill is rated for primary workpiece materials including steel, alloy steel, cast iron, titanium, and titanium alloy, corresponding to material codes P, K, S, and H. The straight-cylindrical shank with a 14.00 mm diameter seats securely in standard drill chucks and collet holders. The right-hand spiral flute design supports chip evacuation in blind hole, cross hole, and through-hole drilling scenarios. Coolant-through capability makes it well-suited for deep-hole operations where heat management is critical.

Key Features

• Solid carbide construction for rigidity and wear life in ferrous and exotic materials
• EgiAs coating for extended tool life and reduced built-up edge in steel and titanium
• 140-degree point angle with R-thinned web for self-centering entry and lower thrust force
• Coolant-through design supports heat control in blind hole and deep drilling applications
• 5xD flute-to-diameter ratio provides depth capacity with efficient chip evacuation
• Tapered web configuration with regular spiral for consistent cutting performance

Compatibility

Part of OSG Series 6510, designed for high-performance drilling in steel, alloy steel, cast iron, titanium, and titanium alloy workpieces. Compatible with standard drill chucks and collet holders accepting a 14.00 mm straight-cylindrical shank. Suitable for use within the 12.50 mm to 15.00 mm drill bit size range of this series.

Installation Notes

Installation and tool changes should be performed by qualified machinists with the machine powered down and locked out per facility LOTO procedures. Ensure the shank is fully seated and properly torqued in the chuck or collet holder before operation. When using coolant-through capability, verify that coolant supply lines and pressure settings are compatible with the machine spindle before engaging the drill. Inspect the cutting edges and coating for wear or chipping before each use and replace the tool if damage is observed.
