Osg 8608226 Screw Machine Drill Bit 0.089 in Xpm

Product Description

The OSG 8608226 is a screw machine length drill bit designed for high-performance metal drilling in production and maintenance environments. Built from XPM high-speed steel with a coated finish, it carries a 130-degree drill point angle optimized for work in steel, alloy steel, cast iron, and nickel alloys. The bit measures 45 millimeters in overall length with a 13-millimeter flute length, features a straight-cylindrical shank, and runs a right-hand spiral flute with a tapered, X-thinned web. It is sold as a single bit per package and is handled by machinists, toolroom technicians, and production drilling crews.

This bit fits short-reach screw machine drilling applications where stub-length rigidity matters. The screw machine length format reduces deflection compared to jobber-length bits, making it well suited for CNC drill presses, turret lathes, and manual machine tools working in ferrous and nickel-based workpiece materials. The 3xD flute-to-diameter ratio supports chip evacuation in blind and through-hole operations at moderate feed rates. Coolant-through capability is not available on this model.

Key Features

• XPM high-performance high-speed steel construction with coated finish for extended tool life in ferrous materials
• 130-degree drill point angle with standard point geometry suited for steel, alloy steel, cast iron, and nickel alloys
• X-thinned, tapered web reduces thrust and improves penetration in harder workpiece materials
• Screw machine length body increases rigidity and reduces deflection versus jobber-length drills
• Right-hand cut, two-flute spiral design promotes consistent chip clearing
• Straight-cylindrical shank fits standard drill chucks and collet holders without modification

Compatibility

Designed as an OEM-style screw machine length drill bit for use in steel, alloy steel, cast iron, and nickel alloy workpieces; fits standard drill chucks and collet systems accepting a 3.00-millimeter straight-cylindrical shank.

Installation Notes

Installation and use of this drill bit should be performed by machinists or toolroom personnel familiar with machine tool operation and cutting tool setup. Ensure the machine spindle is fully stopped and all energy sources are locked out before changing tooling. Secure the shank fully in the chuck or collet to the recommended engagement depth specified by the machine manufacturer. Do not exceed the feed and speed parameters appropriate for the workpiece material and machine rigidity.
