Osg 8608457 Screw Machine Drill Bit 0.18 in Xpm

Product Description

The OSG 8608457 is a screw machine length drill bit designed for high-performance drilling in steel, alloy steel, cast iron, and nickel alloy. It measures 0.18 inches (wire size 15) in diameter and features an XPM high-performance coating over a straight-cylindrical shank. The 130-degree split point angle and R-thinned web reduce entry force and improve chip evacuation. With a flute-to-diameter ratio of 3xD and a regular spiral flute configuration, this bit is built for productivity in demanding shop and field environments. It is sold individually and suited for machinists, tool-and-die professionals, and maintenance technicians working with hard or abrasive ferrous materials.

This drill bit fits applications involving steel and alloy steel fabrication, cast iron machining, and nickel alloy work where standard HSS tooling falls short. The screw machine length format keeps the bit compact and rigid, making it well suited for drill press, CNC, and manual machine use where short-reach setups are required. It is commonly used in production environments, job shops, and industrial maintenance applications that demand consistent hole quality and extended tool life in tough workpiece materials.

Key Features

• XPM high-performance coating for extended tool life in ferrous and hard materials
• 130-degree point angle with R-thinned web for reduced thrust and faster penetration
• Right-hand cut with regular spiral flute for efficient chip removal
• Screw machine length for maximum rigidity in short-reach drilling setups
• Straight-cylindrical shank compatible with standard drill chucks and collets
• Diameter tolerance of plus 0 to minus 0.0007 inches for precise hole sizing

Compatibility

Designed as an OEM-style replacement or production tooling option for applications requiring a wire size 15 (0.18-inch) screw machine length drill bit in steel, alloy steel, cast iron, and nickel alloy workpieces.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or maintenance technicians familiar with machine tool operation. Secure the straight-cylindrical shank fully in the chuck or collet before operation and verify runout is within acceptable limits. Follow all machine guarding requirements and use appropriate cutting fluid or coolant for the workpiece material. Do not exceed the recommended speed and feed parameters for the material being drilled.
