The OSG 8665530 is a screw machine length drill bit designed for high-performance drilling in demanding metalworking applications. Built from solid carbide and coated with OSG's proprietary WXL finish, this bit delivers extended tool life and thermal resistance in tough materials. It features a 140-degree point angle with R-thinned web geometry, which reduces thrust and improves chip evacuation at entry. The 5.30 mm diameter and 82.00 mm overall length make it well suited for short-hole drilling where rigidity and precision matter. Coolant-through capability supports high-speed machining cycles in production environments. This bit is intended for installation and use by machinists and tool-and-die professionals.
This drill bit is engineered for cutting steel, stainless steel, cast iron, and high-temperature alloys. The screw machine length format provides a shorter, stiffer profile compared to jobber-length bits, making it a common choice for CNC machining centers, drill presses, and turret lathes where minimal deflection is critical. The straight cylindrical shank with a 6.00 mm shank diameter fits standard collets and drill chucks designed for metric tooling. The 3xD flute-to-diameter ratio supports efficient chip removal in blind and through-hole operations.
Designed for use in CNC machining centers, drill presses, and turret lathes equipped with collets or chucks accepting a 6.00 mm straight cylindrical shank. Primary workpiece materials include steel, stainless steel, cast iron, and high-temperature alloys per OSG Series 5200 specifications.
This tool should be installed and operated by qualified machinists familiar with carbide tooling. Ensure the spindle and tool holder are clean and properly torqued before beginning a cut. Carbide bits are brittle and should not be used in hand drills or unstable fixturing where lateral loading or chatter may occur. Verify coolant-through pressure and flow rate are appropriate for the machine setup before running production cycles.
