Osg 8672330 Solid Carbide Jobber Drill Bit 3.3 Mm

Product Description

The OSG 8672330 is a solid carbide jobber-length drill bit designed for high-performance drilling in ferrous materials. It measures 3.3 mm in diameter with an overall length of 74 mm and a flute length of 28 mm. The bit features a 140-degree X-thinned point for improved self-centering and reduced thrust, and an EgiAs coating that extends tool life in demanding applications. The straight-cylindrical shank measures 4.0 mm in diameter, compatible with standard drill chucks and collet systems. This bit is part of the OSG Series 6310, engineered for precision drilling in production and maintenance environments. It is sold individually and suited for use by machinists, tool-and-die professionals, and maintenance technicians.

The OSG 8672330 is intended for drilling in steel, alloy steel, and cast iron. It handles blind hole, cross hole, through-hole, and self-centering drilling operations. The 5xD flute-to-diameter ratio supports chip evacuation in moderately deep holes. This bit is a fit for CNC machining centers, drill presses, and handheld power tools where a precision carbide bit is required for hard or abrasive ferrous workpieces.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous materials
• EgiAs coating for extended tool life and reduced built-up edge
• 140-degree X-thinned point for self-centering entry and reduced thrust force
• Right-hand spiral flute with regular helix for consistent chip evacuation
• Tapered web configuration with X-thinned geometry reduces walking on entry
• Diameter tolerance of plus 0 to minus 0.018 mm for tight hole accuracy

Compatibility

Designed for drilling steel, alloy steel, and cast iron workpieces. Suitable for blind hole, cross hole, standard drilling, and self-centering applications across Series 6310 tooling setups. No coolant-through capability; intended for external coolant or dry cutting conditions.

Installation Notes

Installation and use should be performed by qualified machinists or tooling professionals familiar with carbide cutting tools. Secure the straight-cylindrical shank firmly in a matched collet or drill chuck before operation to prevent runout. Carbide bits are brittle and susceptible to chipping if subjected to side loads or impact; do not use in hammer-drill mode. Inspect the cutting edge and coating condition before each use and replace the bit if chipping or excessive wear is observed.
