Osg 8608279 Screw Machine Drill Bit 7/64 Inch Xpm

Product Description

The OSG 8608279 is a screw machine length drill bit designed for high-performance drilling in ferrous and hard metals. It measures 0.11 inches (7/64 inch) in diameter with an overall length of 1.81 inches (46.00 mm) and a flute length of 0.63 inches (16.00 mm). The 130-degree split point and X-Thinned web reduce thrust and improve centering without a pilot hole. XPM high-speed steel construction with a coated finish delivers extended tool life in demanding production environments. Licensed HVAC technicians, machinists, and trade professionals working with tight-tolerance fastener holes in steel and alloy materials will find this bit suited to screw machine and production drilling applications.

The OSG 8608279 is built for drilling into steel, alloy steel, cast iron, and nickel alloy workpieces. Its screw machine length — shorter than a jobber bit — provides rigidity and reduced deflection when working in drill presses, CNC machines, and screw machines. The 3xD flute-to-diameter ratio and regular spiral flute geometry support consistent chip evacuation in these materials. This bit is sold individually and is appropriate for shops and field technicians maintaining tight hole tolerances in production or repair work.

Key Features

• XPM high-performance high-speed steel with coated finish for extended wear resistance
• 130-degree drill point angle with X-Thinned web for reduced thrust and self-centering entry
• Screw machine (stub) length for increased rigidity and reduced deflection
• Right-hand cut, regular spiral flute for consistent chip evacuation
• Straight-cylindrical shank compatible with standard drill chucks and collets
• Diameter tolerance of +0 to -0.014 mm for precise hole sizing

Compatibility

Designed for use in steel, alloy steel, cast iron, and nickel alloy workpieces as specified by OSG Series 1900. Compatible with standard drill chucks and collet holders accepting a 3.00 mm (0.118 inch) straight-cylindrical shank. Coolant-through is not supported on this bit.

Installation Notes

Install and remove this bit only with the machine powered off and brought to a complete stop. Secure the straight shank fully in the chuck or collet to the recommended grip depth before operation. Use appropriate cutting fluid for ferrous metals to extend tool life and maintain hole quality. Follow applicable OSHA machine guarding and PPE requirements when operating drill presses or CNC equipment.
