Osg 8623224 Extra Length Cobalt Drill Bit 0.0945 in

Product Description

The OSG 8623224 is a cobalt extra length drill bit designed for demanding drilling applications where standard-length bits fall short. Built from cobalt high-speed steel with a WXL surface finish, this bit delivers extended tool life in hard and abrasive materials. It features a 120-degree drill point angle, a right-hand spiral flute, and R-thinned web geometry that reduces thrust and improves chip evacuation. With a 2-flute spiral design and straight-cylindrical shank, it seats securely in standard drill chucks and collets. Machinists and tool-and-die professionals rely on this geometry for accurate starts and clean hole finishes in production environments.

This extra length drill bit is suited for metalworking applications that require greater reach than jobber-length tooling allows. Typical uses include deep-hole drilling in steel, stainless, cast iron, and other ferrous materials. The cobalt construction makes it a practical choice for materials that generate high cutting heat. The 20xD flute-to-diameter ratio provides the depth-to-diameter clearance needed for through-hole work in plate, block, and structural components. It is intended for use in CNC machining centers, drill presses, and manual milling operations.

Key Features

• Cobalt construction resists heat and wear in hard ferrous and abrasive materials
• WXL finish reduces friction and extends cutting edge life
• 120-degree drill point angle suits general-purpose and hard-material drilling
• R-thinned web reduces axial thrust and improves chip flow
• 20xD flute-to-diameter ratio enables deep-reach drilling beyond standard jobber lengths
• Straight-cylindrical shank fits standard drill chucks and ER collets without adapters

Compatibility

Designed as a direct-fit extra length drill bit for use in standard drill chucks and straight-shank collet systems accepting a 2.00 mm shank diameter.

Installation Notes

Installation and use should be performed by qualified machinists or tooling technicians familiar with cutting tool setup. Ensure the machine spindle is fully stopped and locked out before inserting or removing the bit. Secure the straight shank with proper chuck or collet torque to prevent slippage under load. Follow applicable shop safety standards and machine manufacturer guidelines for speed and feed selection when working with cobalt tooling in hard materials.
