Osg 9599040 Screw Machine Drill Bit 0.1575 in Xpm

Product Description

The OSG 9599040 is a screw machine length drill bit engineered for high-performance metal cutting applications. Built from XPM high-speed steel with an applied coating, this bit delivers consistent performance in demanding production and maintenance environments. It measures 4.00 mm (0.1575 inches) in diameter with an overall length of 54.00 mm (approximately 2.13 inches) and a flute length of 22.00 mm (approximately 0.87 inches). The 130-degree split point and R-thinned web reduce walking and lower thrust requirements at the start of a cut. Licensed machinists, tool-and-die technicians, and maintenance professionals working with ferrous metals rely on this geometry for accurate, efficient hole making.

This drill bit is designed for use in CNC machining centers, drill presses, and hand-held power tools where a compact screw machine length is preferred over jobber or aircraft-extension lengths. The shorter flute-to-diameter ratio of 3xD provides added rigidity, making it well suited for interrupted cuts, cross-holes, and close-tolerance work in steel, alloy steel, cast iron, and nickel alloy workpieces. It is sold individually and fits standard drill chucks accepting a 4.00 mm (0.1575 inch) straight cylindrical shank.

Key Features

• XPM high-performance high-speed steel construction with applied coating for extended tool life in ferrous materials
• 130-degree drill point angle with R-thinned, tapered web for reduced thrust and self-centering entry
• Screw machine length body with 3xD flute-to-diameter ratio for increased rigidity over jobber-length bits
• Right-hand cut, two-flute spiral configuration for efficient chip evacuation
• Straight cylindrical shank compatible with standard drill chucks and collets
• Diameter tolerance of +0 to -0.018 mm for consistent, repeatable hole sizing

Compatibility

Designed as an OEM-style replacement or production-grade tooling option for applications requiring a 4.00 mm (0.1575 inch) diameter screw machine length drill bit in the OSG Series 1900 product family, suitable for primary workpiece materials including steel, alloy steel, cast iron, and nickel alloy.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance technicians familiar with rotating cutting tool safety. Secure the shank fully in a properly sized drill chuck or collet and verify runout before commencing a cut. Always power down and lock out the machine before changing or inspecting tooling. Follow applicable shop safety standards and wear appropriate eye and hand protection when operating drilling equipment.
