Osg 8594066 Jobber Drill Bit 6.6 Mm Ticn Hss

Product Description

The OSG 8594066 is a jobber-length drill bit engineered for high-performance drilling in metal, alloy, and general-purpose shop applications. Built from vanadium high speed steel with a TiCN (titanium carbonitride) coating, it delivers improved wear resistance and longer tool life compared to uncoated HSS bits. The 120-degree split point with X-thinned web reduces thrust force and improves center starting without a pilot hole. At 101 mm overall length with a 63 mm flute length, it fits standard drill chucks and machining centers used daily by machinists, maintenance techs, and fabricators.

This bit is suited for production and maintenance drilling in ferrous and non-ferrous materials. The fast spiral flute promotes efficient chip evacuation, making it a reliable choice for through-hole work in steel plate, structural members, HVAC sheet metal, electrical enclosures, and plumbing fixture installations. The straight-cylindrical shank seats securely in keyless and keyed chucks across a wide range of handheld drills, drill presses, and CNC machines.

Key Features

• TiCN coating increases surface hardness and reduces friction for extended bit life
• Vanadium high speed steel construction handles elevated cutting temperatures
• 120-degree point angle with X-thinned web minimizes walking and reduces required thrust
• Fast spiral flute promotes rapid chip clearing in deep or blind holes
• Tapered web configuration adds core strength without sacrificing cutting efficiency
• Straight-cylindrical shank compatible with standard chucks and collets

Compatibility

Designed as an OEM-style jobber-length drill bit for use in standard three-jaw drill chucks, collet holders, and CNC tool holders accepting a 6.6 mm straight-cylindrical shank.

Installation Notes

Secure the shank fully in the chuck and confirm runout is within acceptable limits before drilling. Always wear appropriate eye protection and secure the workpiece before operation. Use cutting fluid when drilling ferrous materials to extend bit life and maintain dimensional accuracy. Inspect the cutting edges and coating condition before each use; a chipped or worn edge should be replaced rather than reused.
