Osg 8623082 Extra Length Cobalt Drill Bit 0.3228 in

Product Description

The OSG 8623082 is a cobalt extra-length drill bit engineered for demanding metal drilling applications where standard-length bits fall short. Built from M6K-grade high-performance cobalt steel and finished with OSG WXL coating, it delivers extended tool life and heat resistance under aggressive feed rates. The bit measures 0.3228 inches in diameter — matching a letter-size P drill — with an overall length of approximately 8.66 inches (220 mm) and a flute length of approximately 5.83 inches (148 mm). The 120-degree standard point angle and R-thinned web reduce entry thrust and improve chip evacuation. This bit is installed by machinists, tool-and-die professionals, and maintenance technicians working in production or MRO environments.

This extra-length bit is suited for deep-hole drilling in steel, stainless steel, cast iron, and other ferrous materials where standard-reach tooling cannot reach the required depth. The fast spiral flute promotes efficient chip removal in deep-bore operations. It is commonly used in vertical mills, drill presses, and CNC machining centers. Typical applications include through-holes in thick plate, deep boss features, and cross-drilling in structural components. The straight-cylindrical shank fits standard drill chucks and collet holders without special adapters.

Key Features

• M6K cobalt steel construction for high heat resistance and extended tool life in ferrous materials
• WXL finish reduces friction and improves wear resistance at the cutting edge
• R-thinned web reduces thrust force at drill entry and improves centering
• Fast spiral flute design promotes chip evacuation in deep-hole drilling
• 120-degree standard point angle suits a broad range of ferrous workpiece materials
• Tapered web configuration and 2-flute design provide stability through the full flute length

Compatibility

Designed as an OEM-style extra-length drill bit for use in standard drill chucks and collet holders accepting a 0.3228-inch straight-cylindrical shank, as part of OSG Series 1750.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance technicians familiar with rotating cutting tools. Secure the shank fully in the chuck or collet and verify runout before starting the cut. Always set spindle speed and feed rate appropriate to the workpiece material and drill diameter before engaging the cut. Use appropriate cutting fluid or coolant — note this bit does not have through-coolant capability, so external coolant application is required for deep-hole operations.
