Osg 9599030 Screw Machine Drill Bit 3mm Xpm Coated

Product Description

The OSG 9599030 is a screw machine length drill bit designed for high-performance drilling in steel, alloy steel, cast iron, and nickel alloy workpieces. Built to Series 1900 standards, it features a 3.00 mm (0.1181 inch) diameter with a straight-cylindrical shank and a 130-degree point angle suited for harder ferrous and nickel-based materials. The XPM coating enhances wear resistance and heat tolerance during high-speed operations. With a flute length of 16.00 mm and an overall length of 48.00 mm, this stub-length bit offers greater rigidity than jobber-length equivalents, reducing deflection in precision drilling applications. Installed by machinists and tooling professionals in production and maintenance environments.

This bit is built for use in CNC machining centers, drill presses, and manual lathes where a rigid, short-length drill is required. The 3xD flute-to-diameter ratio and tapered web with X-thinning geometry reduce thrust and improve chip evacuation in tough ferrous and nickel alloy materials. Typical applications include production drilling in steel fabrication, metalworking shops, and maintenance machining environments where consistent hole quality and tool life are priorities. Right-hand cut, spiral flute configuration is standard for conventional drilling setups.

Key Features

• 3.00 mm (0.1181 inch) diameter with a diameter tolerance of +0 to -0.014 mm for precise hole sizing
• XPM coating provides enhanced wear resistance and thermal protection in hard ferrous and nickel alloy materials
• 130-degree split point angle reduces walking and is optimized for harder workpiece materials
• X-thinned tapered web lowers cutting thrust and improves chip flow
• Screw machine (stub) length at 48.00 mm overall increases rigidity and reduces deflection versus jobber-length drills
• Right-hand spiral flute with straight-cylindrical shank for standard drill chuck compatibility

Compatibility

Designed for use in standard drill chucks and collets accepting a 3.00 mm straight-cylindrical shank. Suitable for drilling steel, alloy steel, cast iron, and nickel alloy workpieces as specified by the manufacturer.

Installation Notes

Installation and use should be performed by qualified machinists or tooling professionals familiar with cutting tool safety. Ensure the machine spindle is fully stopped and the tool holder is properly secured before inserting or removing the bit. Use appropriate cutting fluid or coolant as required by the workpiece material to maintain tool life, noting this bit does not have through-coolant capability. Follow applicable shop safety protocols and equipment manufacturer guidelines for RPM selection based on workpiece material and drill diameter.
