Osg 9599090 Screw Machine Drill Bit 0.3543 in Xpm

Product Description

The OSG 9599090 is a screw machine length drill bit engineered for high-performance metal cutting applications. It measures 9.00 mm (0.3543 inches) in diameter with an overall length of 90.00 mm (3.543 inches) and features a 130-degree split point for accurate positioning and reduced walking on entry. The bit is manufactured from XPM high-speed steel with a coated finish to extend tool life under demanding cutting conditions. With a right-hand spiral flute and R-thinned web, it delivers efficient chip evacuation and reduced thrust in short-hole drilling operations. This bit is sized and constructed for production and maintenance environments where dimensional accuracy and tool durability are critical.

The OSG 9599090 is suited for drilling into steel, alloy steel, cast iron, and nickel alloy workpieces in both production shop and field maintenance settings. Its screw machine length profile — shorter than jobber length — provides added rigidity in drill press, mill, and CNC turret applications where stub-length control is preferred. The 3xD flute-to-diameter ratio supports controlled chip removal in moderate-depth holes. Machinists, tool-and-die technicians, and maintenance mechanics working with ferrous and nickel-based materials will find this bit appropriate for high-cycle drilling tasks.

Key Features

• 9.00 mm (0.3543 inches) diameter with tight tolerance of plus 0 to minus 0.022 mm
• 130-degree standard point with R-thinned, tapered web for reduced entry thrust
• XPM high-performance high-speed steel construction with coated finish
• Right-hand cut, regular spiral, two-flute design for efficient chip evacuation
• Screw machine (stub) length body at 90.00 mm overall for added rigidity
• No coolant-through; suitable for conventional drilling setups

Compatibility

Designed for use on steel, alloy steel, cast iron, and nickel alloy workpieces. Part of OSG Series 1900 and fits within the 0.3500 to 0.4000 inch (8.00 to 9.50 mm) drill bit size range. Accepts standard straight-cylindrical shank tool holders with a 10.00 mm shank diameter.

Installation Notes

Installation and use should be performed by machinists or qualified maintenance technicians familiar with rotating cutting tools. Secure the shank fully in the chuck or collet before operation and confirm runout is within acceptable limits for the application. Power down and de-energize the machine spindle before changing or inspecting the bit. Follow applicable shop safety standards and the machine manufacturer guidelines for speed and feed recommendations based on workpiece material.
