Osg 8690600 Solid Carbide Screw Machine Drill Bit 0.2362 in

Product Description

The OSG 8690600 is a solid carbide screw machine length drill bit designed for high-performance drilling in demanding metalworking applications. Built to Series 6500 specifications, it features a 0.2362-inch (6.00 mm) diameter, a 140-degree split point, and a coated finish that extends tool life in tough materials. The stub-length body keeps the bit rigid and minimizes deflection during entry. With coolant-through capability and a right-hand spiral flute design, this bit maintains chip evacuation and thermal control at elevated feed and speed rates. It is sized for use in CNC machining centers, drill presses, and screw machine setups where tight tolerances and consistent hole quality are required.

This drill bit is engineered for use in steel, alloy steel, cast iron, titanium, and titanium alloy workpieces. The screw machine (stub) length is well suited to short-reach applications where rigidity matters more than depth capacity. Typical install scenarios include production machining environments and job shop operations drilling precision holes in ferrous and non-ferrous hard metals. The straight-cylindrical shank seats directly in standard drill chucks or collets without additional adapters.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard metals
• 140-degree drill point angle reduces thrust and self-centers on entry
• Coolant-through design supports internal flood or mist cooling at the cutting edge
• R-thinned web configuration lowers cutting resistance and improves chip flow
• Regular spiral flute with 3xD flute-to-diameter ratio for efficient chip evacuation
• Coated finish extends tool life in steel, cast iron, and titanium alloys

Compatibility

Designed as a high-performance screw machine length drill bit suitable for CNC machining centers, drill presses, and screw machines using standard straight-cylindrical shank toolholders in the 0.2000 to 0.2500-inch diameter range. Primary workpiece materials include steel, alloy steel, cast iron, titanium, and titanium alloy.

Installation Notes

Installation is performed by machinists and tooling technicians. Ensure the machine spindle is fully stopped and the tool holding system is clean and free of debris before seating the shank in the chuck or collet. Verify runout after clamping, as solid carbide is more brittle than high-speed steel and sensitive to lateral load. Follow the machine manufacturer and tooling guidelines for appropriate feed rates and spindle speeds for the target material and coolant delivery method.
