Osg 8608397 Screw Machine Drill Bit 5/32 in 130 Xpm

Product Description

The OSG 8608397 is a screw machine length drill bit designed for high-performance drilling in ferrous and hard metals. It measures 0.1562 inches (5/32 inch) in diameter and features a 130-degree drill point angle with XPM high-performance steel construction and a coated finish. The stub-length body keeps the bit rigid and reduces deflection in short-hole applications. With two spiral flutes and an X-thinned web, this bit cuts efficiently with reduced thrust. It is sized for use in CNC machining centers, drill presses, and hand-held power tools by machinists and metalworking professionals.

This drill bit is intended for use on steel, alloy steel, cast iron, and nickel alloys in production and maintenance machining environments. The screw machine (stub) length format makes it well suited for applications where clearance is limited or rigidity is critical, such as drilling into workpieces held in vises or fixtures. The straight-cylindrical shank fits standard drill chucks and collets without modification. It is part of the OSG Series 1900 lineup and carries a flute-to-diameter ratio of 3xD.

Key Features

• XPM high-performance tool material with coated finish for extended tool life in hard metals
• 130-degree drill point angle suits harder workpiece materials including cast iron and nickel alloy
• X-thinned web reduces thrust and improves chip evacuation
• Screw machine (stub) length body provides maximum rigidity and minimizes deflection
• Right-hand cut with regular spiral flutes for standard clockwise drilling operations
• Straight-cylindrical shank fits standard drill chucks and collets

Compatibility

Designed for drilling steel, alloy steel, cast iron, and nickel alloy workpiece materials. Fits any drill chuck or collet accepting a 4.00 mm (approximately 0.157 inch) straight-cylindrical shank. Part of the OSG Series 1900 screw machine length drill bit line.

Installation Notes

This bit is installed by machinists and metalworking technicians in machine shop and maintenance settings. Secure the shank fully in the chuck or collet before operation and verify runout is within acceptable limits. Use appropriate cutting fluid or coolant for the workpiece material to maintain tool life, noting this bit does not have coolant-through capability. Inspect the cutting edges for wear or chipping before each use and replace if the point geometry is compromised.
