Osg 8690510 Screw Machine Drill Bit 0.2008 in Carbide

Product Description

The OSG 8690510 is a solid carbide screw machine length drill bit designed for high-performance drilling in demanding industrial and machining applications. Built to Series 6500 standards, it features a 0.2008-inch (5.10 mm) diameter with a 140-degree drill point angle optimized for reduced thrust and accurate self-centering on tough materials. The straight-cylindrical shank measures 6.00 mm in diameter and fits standard chucks without modification. With two spiral flutes, R-thinned web, and coolant-through capability, this bit is engineered for production environments where tool life and hole quality are critical. Machinists, toolmakers, and CNC operators working in metal cutting applications will find this a reliable choice for high-cycle drilling.

The OSG 8690510 is suited for drilling steel, alloy steel, cast iron, titanium, and titanium alloys. Its screw machine length body and 3xD flute-to-diameter ratio make it appropriate for close-tolerance work in CNC machining centers, drill presses, and multi-spindle setups. The short overall length of 82.00 mm (approximately 3.23 inches) provides rigidity and minimizes deflection, which is especially valuable when holding tight tolerances on hardened or abrasion-resistant workpieces. It is a practical choice for job shops and production facilities running ferrous and non-ferrous metal components.

Key Features

• Solid carbide construction for extended tool life in hard and abrasive workpiece materials
• 140-degree drill point angle reduces thrust and improves self-centering on entry
• Coolant-through design supports high-speed production drilling and chip evacuation
• R-thinned, tapered web configuration reduces cutting resistance at the chisel edge
• Straight-cylindrical shank compatible with standard collet chucks and drill chucks
• Coated finish improves wear resistance and heat dissipation during continuous use

Compatibility

Designed for use in steel, alloy steel, cast iron, titanium, and titanium alloy workpieces. Fits standard chucks accepting a 6.00 mm straight-cylindrical shank. Part of the OSG Series 6500 high-performance carbide drill line.

Installation Notes

Installation and setup should be performed by a qualified machinist or CNC operator. Ensure the spindle and chuck are fully powered down and locked out before changing tooling. Verify chuck or collet runout is within acceptable limits before use, as excessive runout will accelerate wear on carbide tooling. Always confirm coolant flow is active and directed to the cutting zone when using the through-coolant feature.
