Osg 8623027 Extra Length Cobalt Drill Bit 0.1063 in

Product Description

The OSG 8623027 is a cobalt extra-length drill bit designed for precision drilling in tough materials where standard-length bits fall short. Built from cobalt high-speed steel and finished with OSG WXL coating, this bit delivers extended tool life in difficult-to-machine metals including stainless steel, hardened alloys, and heat-resistant materials. It features a 120-degree point angle with proprietary point geometry, a right-hand spiral flute with R-thinned web for reduced thrust and cleaner starts, and a 15xD flute-to-diameter ratio that provides deep-reach capability. Machinists and tool-and-die professionals are the primary installers of this bit in production and maintenance drilling applications.

This bit is suited for deep-hole drilling operations in metalworking environments, including CNC machining centers, drill presses, and manual machine tools. Its straight-cylindrical shank seats in standard drill chucks and collet holders without modification. The 2.70 mm (0.1063 inches) cutting diameter and 50.00 mm flute length make it appropriate for applications requiring precision hole depth in metal fabrication, aerospace component work, mold and die work, and general industrial machining where an extended reach past standard jobber-length bits is required.

Key Features

• Cobalt high-speed steel construction for heat and wear resistance in hard metals
• WXL finish coating reduces friction and extends tool life in abrasive materials
• 120-degree drill point angle with proprietary point geometry for accurate starts
• R-thinned web reduces cutting thrust and improves chip evacuation
• 15xD flute-to-diameter ratio enables deep-reach drilling beyond standard jobber length
• Straight-cylindrical shank compatible with standard chucks and collet holders

Compatibility

Designed as an OEM-style extra-length cobalt drill bit for use in standard drill chucks and collet systems accepting a 3.00 mm straight-cylindrical shank in CNC and manual machine tool applications.

Installation Notes

Installation is performed by machinists and tool operators in machine shop environments. Ensure the machine spindle is fully stopped and de-energized before changing bits, and confirm the shank is fully seated and the chuck or collet is properly torqued before operation. Use appropriate cutting fluid or coolant for the workpiece material, noting this bit does not support through-coolant. Follow applicable shop safety protocols and machine manufacturer guidelines for spindle speed and feed rate selection based on workpiece material.
