Osg HP255-2047 Solid Carbide Jobber Drill Bit 5.2mm

Product Description

The OSG HP255-2047 is a solid carbide jobber-length drill bit engineered for high-performance drilling in ferrous materials. It carries a 5.2 mm diameter, a 140-degree R-thinned point, and an overall length of 82 mm with a 44 mm flute length. The WD1 coating improves wear resistance and heat dissipation during extended production runs. The straight-cylindrical shank measures 6.0 mm in diameter and seats securely in standard drill chucks and collet holders. A regular spiral flute with tapered web geometry promotes efficient chip evacuation in blind-hole and through-hole applications. This bit is suited for machinists, tool-and-die shops, and maintenance technicians running CNC or manual drilling operations.

The HP255-2047 is designed for drilling steel, alloy steel, and cast iron. Its R-thinned point geometry supports self-centering entry and reduces thrust load, making it well suited for cross-hole, blind-hole, and general drilling operations. The 5xD flute-to-diameter ratio provides added depth capacity relative to its diameter. The right-hand cut configuration is compatible with standard spindle rotation on CNC machining centers, drill presses, and hand-held power tools. This bit is sold individually and is appropriate for both production and maintenance environments where carbide-grade tooling is specified.

Key Features

• Solid carbide construction for rigidity and heat resistance in ferrous workpieces
• WD1 coating for enhanced wear resistance and extended tool life
• 140-degree R-thinned point for self-centering entry and reduced thrust
• Tapered web with R-thinned geometry improves chip flow in blind and cross holes
• 5xD flute-to-diameter ratio supports deeper drilling relative to bit diameter
• Coolant-through capability for high-speed or deep-hole applications

Compatibility

Compatible primary workpiece materials include steel, alloy steel, and cast iron (ISO material codes P and K). Designed for use in CNC machining centers, drill presses, and similar equipment accepting a 6.0 mm straight-cylindrical shank. Tool application includes blind hole, cross hole, general drilling, and self-centering operations.

Installation Notes

Installation should be performed by a qualified machinist following standard tooling practices. Confirm the spindle is fully stopped and the machine is locked out before changing or seating the bit. Ensure the shank is fully seated and the collet or chuck is torqued to the equipment manufacturer's specification. Verify coolant-through lines are clear and pressurized before engaging high-speed cutting cycles.
