Osg 3334352 Screw Machine Drill Bit 6.80mm Solid Carbide

Product Description

The OSG 3334352 is a solid carbide screw machine length drill bit designed for high-performance drilling in ferrous materials. With a 6.80 mm (0.2677 inch) cutting diameter and a 180-degree web-thinned point, this bit produces accurate, clean entry holes with reduced thrust force. The EgiAs coating improves wear resistance and heat dissipation, extending tool life in demanding production environments. At 70 mm (2.756 inches) overall length with a 30 mm flute length, the stubby screw machine geometry provides maximum rigidity and minimizes deflection in short-reach drilling applications. This bit is installed by machinists, tool and die technicians, and production floor operators.

The OSG 3334352 is suited for drilling steel, alloy steel, and cast iron in CNC machining centers, drill presses, and automated production equipment. The straight-cylindrical shank at 8.00 mm (0.315 inch) diameter seats securely in standard drill chucks and collet holders. Coolant-through capability makes it compatible with through-spindle coolant systems, supporting chip evacuation and thermal management in deep or interrupted cuts. It is a Series 5720 tool rated for high-performance applications where tool rigidity and hole positional accuracy are critical.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous machining
• EgiAs coating on both flutes and drill tip for extended tool life and reduced heat buildup
• 180-degree web-thinned point reduces entry thrust and improves centering accuracy
• Coolant-through design supports through-spindle coolant for chip control and heat management
• Screw machine (stub) length geometry maximizes stiffness and minimizes deflection
• Regular spiral, 2-flute configuration with tapered web for efficient chip evacuation

Compatibility

Designed for use in CNC machining centers, drill presses, and production drilling equipment with standard drill chucks or collet holders accepting an 8.00 mm straight-cylindrical shank. Primary workpiece materials are steel, alloy steel, and cast iron.

Installation Notes

This drill bit is installed by machinists or CNC operators. Power down and de-energize the spindle before loading or removing the tool from any holder. Ensure the shank is fully seated and the chuck or collet is torqued to the machine manufacturer specification before running. When using coolant-through capability, verify coolant pressure and flow rate are within the machine spindle ratings before engaging the cut.
