Osg 8623223 Extra Length Cobalt Drill Bit 2.3 Mm

Product Description

The OSG 8623223 is a cobalt extra-length drill bit designed for drilling through hard and abrasion-resistant materials where standard-length bits cannot reach. At 2.3 mm in diameter with a 95 mm overall length and a 54 mm flute length, it provides extended reach in deep-hole applications. The 120-degree split point reduces walking on entry and lowers thrust requirements. OSG's WXL coating improves surface hardness and heat resistance, extending tool life in demanding production environments. A two-flute spiral design with R-thinned web geometry supports efficient chip evacuation. This bit is handled by machinists and tool-and-die professionals in both manual and CNC drilling operations.

This drill bit suits production and precision drilling in aerospace, automotive, die-mold, and general metalworking applications where a standard-length bit lacks the reach. The straight-cylindrical shank fits standard drill chucks and collets without modification. Right-hand cutting direction is compatible with conventional drill presses, machining centers, and hand-held power tools running standard spindle rotation. The 20xD flute-to-diameter ratio makes it particularly suited to deep-hole work relative to the 2.3 mm diameter.

Key Features

• Cobalt tool material resists heat and wear in hard-metal drilling
• WXL coating adds surface hardness and reduces friction for longer tool life
• 120-degree proprietary point with R-thinned web minimizes drill walk and lowers entry thrust
• 54 mm flute length provides extended reach for deep-hole applications
• Two-flute spiral design promotes consistent chip evacuation
• Straight-cylindrical shank fits standard drill chucks and collets

Compatibility

Designed for use in standard drill chucks and collets accepting a 2.0 mm straight-cylindrical shank, compatible with drill presses, CNC machining centers, and hand-held power tools with right-hand spindle rotation.

Installation Notes

Secure the shank fully in the chuck or collet before operation and verify runout is within acceptable limits for the diameter. Power down and lock out the machine spindle before changing or inspecting bits. Use appropriate cutting fluid or coolant for the workpiece material to maximize tool life; this bit does not support internal coolant through. Handling and grinding of cobalt tools should follow applicable shop safety practices for metalworking dust and swarf.
