Osg 8608287 Screw Machine Drill Bit 0.113 in Xpm

Product Description

The OSG 8608287 is a screw machine length drill bit designed for high-performance drilling in ferrous and hard materials. Built from XPM high-speed steel with a coated finish, this bit cuts right-hand with a standard 130-degree split point and an X-thinned web for reduced entry force and improved chip flow. The straight-cylindrical shank measures 3.00 millimeters in diameter, and the overall length comes in at approximately 1.89 inches (48 mm). It carries two spiral flutes with a regular spiral type and a flute length of approximately 0.63 inches (16 mm). The 3xD flute-to-diameter ratio suits short-reach screw machine applications where rigidity and precision entry matter most. Machinists, tool-and-die techs, and metalworking professionals use this bit for production drilling operations.

This bit is rated for primary workpiece materials including steel, alloy steel, cast iron, and nickel alloy. Its screw machine length makes it the right choice for CNC machining centers, drill presses, and turret lathes where stub-length tooling reduces deflection and maintains hole location accuracy. Wire size designation is Number 33, with a decimal inch diameter of 0.1130. The tapered web configuration combined with X-thinning improves penetration in tougher alloys without sacrificing point geometry stability.

Key Features

• XPM coated high-performance tool material for extended tool life in ferrous materials
• 130-degree standard point angle with X-thinned, tapered web for reduced thrust and clean entry
• Screw machine (stub) length for maximum rigidity and minimal deflection
• Two spiral flutes with regular spiral type for efficient chip evacuation
• Straight-cylindrical shank at 3.00 mm for secure chuck retention
• Diameter tolerance of plus 0 to minus 0.014 mm for consistent hole sizing

Compatibility

Designed as a high-performance screw machine length drill bit suitable for use in steel, alloy steel, cast iron, and nickel alloy workpieces across CNC and manual drilling setups that accept straight-cylindrical shank tooling in the 3.00 mm shank diameter range.

Installation Notes

This bit is installed and serviced by machinists and tool-and-die technicians. Secure the straight-cylindrical shank fully in the chuck or collet before operation and verify runout before drilling production parts. Consult machine manufacturer guidelines for appropriate spindle speed and feed rates based on workpiece material. Do not exceed rated cutting parameters, as overloading a stub-length bit in hard alloys can cause premature edge wear or point chipping.
