Osg 8623237 Extra Length Cobalt Drill Bit 0.1457 in

Product Description

The OSG 8623237 is an extra length cobalt drill bit designed for high-performance drilling in demanding metal-cutting applications. Built from M6K-grade cobalt high-speed steel and finished with OSG WXL coating, this bit delivers extended tool life in tough ferrous and stainless materials. The 120-degree standard point angle combined with R-thinned web geometry reduces entry force and improves centering accuracy. The straight-cylindrical shank measures 0.1457 inches in diameter, matching the cutting diameter for a consistent, secure grip in standard drill chucks or collet holders. Licensed trade professionals and machining specialists turn to this bit when standard-length tooling cannot reach depth.

This drill bit is suited for industrial and shop applications requiring additional reach in confined or deep-hole drilling scenarios. The extra length design accommodates setups where a standard jobber-length bit falls short. At 3.70 millimeters (0.1457 inches) in diameter with a flute length of approximately 3.39 inches and an overall length of approximately 5.31 inches, the 8623237 fits Series 1750 tooling requirements. Applications include drilling in steel, alloy steel, and other hard metals in manufacturing, maintenance, and precision fabrication environments.

Key Features

• M6K cobalt high-speed steel construction for heat and wear resistance in hard metal drilling
• WXL finish reduces friction and extends tool life between sharpenings
• 120-degree standard point angle with R-thinned, tapered web for reduced thrust and accurate self-centering
• Fast spiral flute configuration promotes efficient chip evacuation in deep-hole applications
• Right-hand cutting direction with two flutes and straight-cylindrical shank for broad chuck compatibility
• Diameter tolerance of +0.000 to -0.018 mm for consistent, repeatable hole sizing

Compatibility

Designed as an OEM-style replacement or direct-fit option within OSG Series 1750 extra length drill bit applications.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or trade professionals familiar with cutting tool setup and speeds-and-feeds calculations. Secure the straight-cylindrical shank fully in the chuck or collet before operation to prevent runout. Confirm spindle speed and feed rate are appropriate for the workpiece material and drill diameter before starting the cut. Inspect the cutting edges and web condition before each use and replace or resharpen when wear affects hole quality or thrust increases noticeably.
