Osg 650015511 Screw Machine Drill Bit 5/32 in Carbide

Product Description

The OSG 650015511 is a solid carbide screw machine length drill bit designed for high-performance drilling in demanding production environments. Built to Series 6500 specifications, it features a 5/32 inch (3.97 mm) diameter, a 140-degree point angle with R-thinned web geometry, and an EgiAs coating that reduces friction and extends tool life. At 74 mm (2.91 inches) overall length, the stub-length body provides rigidity and minimizes deflection in short-reach drilling setups. The straight-cylindrical shank measures 0.1875 inches in diameter. This bit is installed by machinists, tool-and-die workers, and maintenance technicians working with drill presses, CNC machining centers, and manual lathes.

The OSG 650015511 is suited for drilling steel, alloy steel, cast iron, titanium, and titanium alloys. The screw machine length format is common in high-volume production drilling where rigidity matters more than reach. Coolant-through capability supports chip evacuation and temperature control in deep-hole or high-cycle applications. The 3xD flute-to-diameter ratio and regular spiral flute design promote consistent chip flow in ferrous and difficult-to-machine materials.

Key Features

• Solid carbide construction for rigidity and heat resistance in ferrous and titanium materials
• EgiAs coating reduces tool wear and friction in high-cycle drilling
• 140-degree point angle with R-thinned web minimizes thrust force and improves centering
• Coolant-through design supports chip evacuation and extended tool life
• Screw machine (stub) length provides enhanced rigidity over jobber-length bits
• Diameter tolerance of plus 0 to minus 0.018 mm for consistent hole quality

Compatibility

Primary workpiece materials include steel, alloy steel, cast iron, titanium, and titanium alloy. Designed for use in drill presses, CNC machining centers, and similar setups that accept a 0.1875 inch straight-cylindrical shank within the 0.1500 to 0.2000 inch drill bit size range.

Installation Notes

Installation is performed by machinists or maintenance technicians. Ensure the machine spindle and workpiece are fully stopped and secured before inserting or removing the bit from the chuck or collet. Verify that the coolant-through supply is compatible with the machine tool before use. Follow shop safety protocols and applicable ANSI machining standards for drill bit handling and tool changes.
