Osg 8595935 Screw Machine Drill Bit 0.3681 in Hss

Product Description

The OSG 8595935 is a screw machine length drill bit designed for high-performance drilling in metal fabrication and machining applications. Built from high speed steel with a coated finish, this bit features a 120-degree faceted drill point, a right-hand spiral flute, and a web-thinned, tapered web configuration that reduces cutting resistance and improves chip evacuation. The straight-cylindrical shank measures 10.00 millimeters in diameter and seats securely in standard drill chucks. At 90.00 millimeters overall length with a 40.00 millimeter flute length, the stub-style body provides added rigidity compared to jobber-length bits, making it well-suited for tight-tolerance work in production environments.

This drill bit is rated for use in steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces. The screw machine length format is commonly specified in CNC machining centers, turret lathes, and drill press setups where shorter tool extension and reduced deflection are required. It falls within the 0.3500 to 0.4000 decimal inch diameter range and carries a Letter U size designation. Machinists and tool-and-die professionals working in production shops will find this bit appropriate for through-hole and blind-hole operations in ferrous and non-ferrous materials.

Key Features

• Screw machine length body for improved rigidity and reduced deflection
• High speed steel construction with coated finish for extended tool life
• 120-degree faceted drill point for accurate self-centering entry
• Web-thinned, tapered web reduces thrust and improves chip flow
• Right-hand spiral flute with 2-flute configuration
• Compatible with a broad range of ferrous and non-ferrous workpiece materials

Compatibility

Designed as a high-performance screw machine length drill bit for use in steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces across the 0.3500 to 0.4000 decimal inch diameter range.

Installation Notes

This bit should be installed by a qualified machinist or tool operator using a properly sized drill chuck or collet matching the 10.00 millimeter shank diameter. Ensure the machine spindle is fully stopped and the work piece is securely clamped before tool changes. Use appropriate cutting fluid for the workpiece material to manage heat and extend tool life. Follow applicable shop safety standards and machine manufacturer guidelines for speed and feed settings.
