Osg 8608373 Screw Machine Drill Bit 0.147 in Xpm

Product Description

The OSG 8608373 is a screw machine length drill bit engineered for high-performance drilling in ferrous and hard materials. It measures 0.147 inches (Wire Size 26) in diameter and features a 130-degree drill point angle designed to reduce thrust and improve self-centering on hard workpieces. The XPM high-speed steel construction with a coated finish extends tool life in demanding production environments. The X-Thinned web improves chip evacuation and cutting efficiency. This bit is suited for machinists, tool and die shops, and maintenance professionals working with production drilling applications.

This drill bit is designed for right-hand cutting in steel, alloy steel, cast iron, and nickel alloy workpieces. The screw machine length format provides added rigidity compared to jobber-length bits, making it a practical choice for close-tolerance holes in CNC machining centers, drill presses, and manual machines where shorter flute length improves stability. The straight-cylindrical shank seats reliably in standard drill chucks and collets. It falls within OSG Series 1900, a line targeting high-performance metal-cutting applications.

Key Features

• XPM high-performance tool material with coated finish for extended wear resistance in ferrous metals
• 130-degree drill point angle reduces entry thrust and improves self-centering on hard materials
• X-Thinned web configuration enhances chip flow and reduces cutting force
• Screw machine length body provides greater rigidity than jobber-length equivalents
• 2-flute spiral design with regular helix suits general metal drilling in steel and cast iron
• Straight-cylindrical shank is compatible with standard drill chucks and collet systems

Compatibility

Designed as a high-performance replacement or production drill bit for applications in steel, alloy steel, cast iron, and nickel alloy workpieces requiring a 0.147-inch diameter hole.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance professionals. Secure the shank fully in the chuck or collet before operation and verify runout is within acceptable limits for the application. Use appropriate cutting fluid or coolant for the workpiece material even though this bit does not feature through-coolant capability. Follow machine manufacturer guidelines and applicable shop safety standards when setting spindle speed and feed rate for the material being drilled.
