Osg 8623227 Extra Length Cobalt Drill Bit 0.1063 in

Product Description

The OSG 8623227 is a cobalt extra length drill bit designed for drilling applications that require deeper reach than standard-length tooling. Built from cobalt high-speed steel with a WXL finish, this bit offers improved wear resistance and heat tolerance compared to standard HSS tooling. The 120-degree drill point angle and R-thinned web reduce entry resistance and improve centering on the workpiece. With a 2-flute spiral configuration and right-hand cutting direction, this bit suits a wide range of ferrous and non-ferrous materials. It is sized at 0.1063 inches (2.70 mm) in diameter and intended for use by machinists, toolmakers, and metalworking tradespeople.

This extra length drill bit is suited for production machining, toolroom work, and fabrication environments where extended reach is required to drill deep holes or access recessed features. The straight-cylindrical shank fits standard drill chucks and collet holders. The 20xD flute-by-diameter ratio indicates a notably long flute section relative to diameter, making this bit appropriate for deep-hole drilling operations in shop and field settings.

Key Features

• Cobalt construction with WXL finish for enhanced wear resistance and heat tolerance
• 120-degree point angle with R-thinned web for reduced entry force and improved self-centering
• 2-flute spiral configuration with regular spiral type for efficient chip evacuation
• Straight-cylindrical shank compatible with standard drill chucks and collet systems
• 20xD flute-by-diameter ratio provides extended reach for deep-hole applications
• Right-hand cutting direction; no coolant-through feature

Compatibility

Designed as a direct-fit replacement or supplemental tooling for any setup accepting a straight-cylindrical shank drill bit at 0.1063 inches (2.70 mm) diameter, including standard drill chucks and collet holders used in bench drills, machining centers, and hand drills.

Installation Notes

Installation and use should be performed by qualified machinists or metalworking tradespeople familiar with drilling tooling and machine operation. Ensure the machine spindle is fully stopped and locked out before inserting or removing the bit from the chuck or collet. Verify shank seating and chuck tightness before beginning any drilling operation. Follow applicable shop safety standards and machine manufacturer guidelines for speed and feed selection.
