Osg 8595483 Screw Machine Drill Bit 0.1902 in Hss

Product Description

The OSG 8595483 is a screw machine length drill bit designed for high-performance drilling in metalworking and machining applications. Built from high speed steel with a coated finish, this bit measures 0.1902 inches (4.83 mm) in diameter and features a 120-degree faceted drill point for accurate starting and clean entry. The web-thinned, tapered web construction reduces thrust and improves chip evacuation. With a straight-cylindrical shank and regular spiral flutes, this bit suits automatic screw machines, drill presses, and CNC drilling operations where short, rigid tooling is required. Licensed machinists and tool-room technicians are the primary installers.

This bit is rated for drilling steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces. The screw machine length format provides a shorter, stiffer profile compared to jobber-length bits, making it well suited for close-tolerance hole work in production environments and tight-clearance setups. The 5xD flute-to-diameter ratio supports efficient chip removal across these materials.

Installation Notes

Installation and use should be performed by qualified machinists or tool-room professionals familiar with rotating cutting tools. Ensure the machine spindle is fully stopped and locked out before changing tooling. Secure the straight-cylindrical shank firmly in a properly sized chuck or collet to prevent slippage during operation. Follow applicable shop safety standards and machine manufacturer guidelines for speeds and feeds when drilling steel or stainless steel workpieces.
