Osg 9599058 Screw Machine Drill Bit 0.2283 in Xpm

Product Description

The OSG 9599058 is a screw machine length drill bit designed for high-performance drilling in ferrous and hard materials. Built from XPM high-speed steel with a coated finish, it delivers improved wear resistance and heat dissipation during continuous metal-cutting operations. The bit measures 0.2283 inches (5.80 mm) in diameter with a 130-degree point angle, a geometry well suited for drilling into steel, alloy steel, cast iron, and nickel alloy without requiring a pilot hole. The straight-cylindrical shank seats cleanly in standard drill chucks and CNC tool holders. This bit is part of the OSG Series 1900 line, intended for production and maintenance machining environments where tool life and dimensional accuracy are priorities.

The 9599058 is a screw machine length bit, meaning it is shorter than a jobber-length drill, which provides greater rigidity and reduced deflection in close-tolerance drilling applications. It is appropriate for use on drill presses, CNC machining centers, and manual lathes in both shop and field maintenance settings. Its 3xD flute-to-diameter ratio and tapered web configuration support chip evacuation in through-hole and blind-hole applications in the 0.2000 to 0.2500 inch diameter range. Machinists, tool-and-die workers, and industrial maintenance technicians are the primary users.

Key Features

• XPM coated high-speed steel construction for extended tool life in ferrous materials
• 130-degree point angle reduces thrust force and improves self-centering on steel and cast iron
• R-thinned web geometry lowers cutting resistance and improves chip flow
• Straight-cylindrical shank compatible with standard drill chucks and collet holders
• Screw machine length body provides greater rigidity and less runout compared to jobber-length bits
• Right-hand spiral flute design with regular helix for balanced chip evacuation

Compatibility

Designed as an OEM-style replacement and standard tooling option within the OSG Series 1900 screw machine length drill bit line, suitable for drilling steel, alloy steel, cast iron, and nickel alloy workpieces in the 0.2000 to 0.2500 inch diameter range.

Installation Notes

This bit should be installed by a qualified machinist or maintenance technician familiar with proper tooling practices. Ensure the machine spindle is fully stopped and locked out before changing tooling. Confirm the shank is fully seated and the chuck or collet is torqued to the tool holder manufacturer's specification before beginning a cut. Do not exceed the recommended feed and speed parameters for the workpiece material to avoid premature edge failure or bit breakage.
