Osg 8690480 Screw Machine Drill Bit 4.80 Mm Solid Carbide

Product Description

The OSG 8690480 is a solid carbide screw machine length drill bit engineered for high-performance drilling in demanding metalworking applications. It features a 4.80 mm cutting diameter, a 140-degree point angle with R-thinned web geometry, and an EgiAs coating designed to extend tool life in hard and abrasive workpiece materials. The overall length is 80.00 mm (3.1496 inches) with a 29.00 mm flute length, making it well suited for tight-clearance drilling operations where stub-length tools are required. Coolant-through capability supports chip evacuation and heat management at higher feed rates. This bit is installed by machinists and tool-and-die professionals in CNC and manual drilling operations.

The OSG 8690480 is designed for drilling steel, alloy steel, cast iron, titanium, and titanium alloys. Its 3xD flute-to-diameter ratio and regular spiral flute configuration are optimized for short-hole drilling cycles in production environments. The straight-cylindrical shank with a 5.00 mm diameter seats securely in standard drill chucks and collet holders. This bit belongs to OSG Series 6500 and is positioned as a high-performance tooling option for shops running tight-tolerance hole programs in ferrous and exotic materials.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard workpiece materials
• EgiAs coating for extended tool life in steel, alloy steel, cast iron, and titanium
• 140-degree point angle with R-thinned web reduces thrust force and improves centering
• Coolant-through design supports chip flushing and thermal control at the cutting edge
• Screw machine (stub) length provides increased rigidity in short-hole applications
• Right-hand cutting, regular spiral flute, tapered web configuration per OSG Series 6500

Compatibility

Compatible with standard drill chucks and collet systems accepting a 5.00 mm straight-cylindrical shank. Rated for use in steel, alloy steel, cast iron, titanium, and titanium alloys per OSG Series 6500 specifications.

Installation Notes

This drill bit is installed by machinists in CNC machining centers or manual drill presses. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Secure the straight-cylindrical shank fully within the collet or chuck to the recommended grip depth before operation. Verify coolant-through lines are clear and flow is confirmed before running at elevated feed rates.
