Osg 8623232 Extra Length Cobalt Drill Bit 3.2 Mm

Product Description

The OSG 8623232 is an extra length cobalt drill bit engineered for demanding drilling applications where standard-length bits fall short. Built from M6K-grade cobalt high-speed steel and finished with OSG WXL coating, this bit delivers extended tool life and heat resistance in tough materials including stainless steel, high-nickel alloys, and hardened steels. It measures 3.2 mm in diameter with a 120-degree point angle, a 74 mm flute length, and a 125 mm overall length. The right-hand spiral flute geometry with fast spiral type and R-thinned web promotes efficient chip evacuation and reduced thrust force at entry.

This drill bit is suited for production machining, toolroom work, and maintenance operations requiring deeper hole depths than standard jobber-length bits allow. The straight-cylindrical shank fits standard drill chucks and collet holders without adapters. Applications include drilling through thick plate, structural steel, stainless fabrication, and aerospace-grade alloys. The Series 1750 designation places this bit in OSG high-performance tooling, appropriate for CNC machining centers, drill presses, and manual machines running coolant-free setups.

Key Features

• M6K cobalt high-speed steel construction for heat and wear resistance in difficult materials
• WXL coating reduces friction and extends cutting tool life
• 120-degree point angle with R-thinned web minimizes thrust and improves centering accuracy
• Fast spiral flute type promotes rapid chip evacuation in deep-hole applications
• 125 mm overall length provides reach for thick workpieces beyond standard jobber-length capability
• Straight-cylindrical shank compatible with standard drill chucks and collet systems

Compatibility

Designed as an OEM-style replacement or direct-fit tooling option for applications requiring a 3.2 mm diameter extra length cobalt drill bit with a straight-cylindrical shank and 120-degree point geometry.

Installation Notes

Installation and use should be performed by qualified machinists or tooling technicians familiar with rotating cutting tools. Secure the shank fully in a properly sized drill chuck or collet before operation and verify runout is within acceptable tolerance for the application. Do not exceed the recommended spindle speeds for the workpiece material and bit diameter. Inspect the cutting edges and coating condition before each use and replace the bit if chipping, excessive wear, or coating breakdown is observed.
