Osg 8692730 Solid Carbide Drill Bit 7.3mm Egias 140deg

Product Description

The OSG 8692730 is a solid carbide jobber length drill bit engineered for high-performance drilling in demanding materials. It features a 7.3 mm diameter, a 140-degree R-thinned point, and an EgiAs coating that extends tool life in abrasive and hard workpiece applications. The overall length is 118 mm with a 59 mm flute length and a 5xD flute-to-diameter ratio. The straight-cylindrical shank measures 8.00 mm in diameter. This bit is designed for use by machinists and tool-and-die professionals on CNC machining centers and drill presses where precision and consistent hole quality are required.

The OSG 8692730 is suited for blind hole, cross hole, and self-centering drilling operations in steel, alloy steel, cast iron, titanium, and titanium alloys. It is classified under ISO material codes P, K, S, and H, making it a versatile choice for job shops and production machining environments. The 2-flute spiral design with regular spiral type promotes efficient chip evacuation, and the coolant-through capability supports high-speed machining cycles with external or internal coolant delivery.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• EgiAs coating for extended tool life in steel, alloy steel, cast iron, titanium, and titanium alloys
• 140-degree R-thinned point for self-centering entry and reduced thrust force
• Coolant-through design supports high-speed machining with internal coolant
• 5xD flute-to-diameter ratio provides deep hole capability with efficient chip clearance
• Diameter tolerance of plus 0 to minus 0.022 mm for consistent hole sizing

Compatibility

Designed for use in CNC machining centers and drill presses as a high-performance jobber length drill in the OSG Series 6510 product line. Compatible with workpiece materials coded P, K, S, and H including steel, alloy steel, cast iron, titanium, and titanium alloys.

Installation Notes

Installation and use should be performed by qualified machinists familiar with carbide tooling and appropriate cutting parameters. Ensure the tool holder and spindle are free of runout before seating the straight-cylindrical shank. When using the coolant-through feature, verify that coolant pressure and flow rate are compatible with the spindle and tool holder setup. Carbide tooling is brittle and should not be subjected to lateral shock loads or used in setups with excessive vibration.
