Osg 8692330 Solid Carbide Jobber Drill Bit 3.3 Mm

Product Description

The OSG 8692330 is a solid carbide jobber-length drill bit designed for high-performance drilling in hard and abrasive materials. Built to Series 6510 standards, it features a 3.3 mm diameter, a 140-degree R-thinned point, and an EgiAs coating that extends tool life in demanding cutting applications. The straight-cylindrical shank measures 4.00 mm in diameter and the overall length is 86 mm. Two spiral flutes with a regular helix and tapered web configuration promote efficient chip evacuation. This bit is suited for machinists, tool-and-die shops, and production drilling operations requiring tight tolerances and consistent performance in ferrous and exotic alloys.

The OSG 8692330 is rated for drilling steel, alloy steel, cast iron, titanium, and titanium alloys, covering material codes P, K, S, and H. It supports blind hole, cross hole, standard through-drilling, and self-centering applications. The 5xD flute-to-diameter ratio and coolant-through capability make it appropriate for CNC machining centers and drill presses where internal coolant delivery is available. Its 30 mm flute length handles moderate-depth holes at this diameter class.

Key Features

• Solid carbide construction for rigidity and heat resistance in hard materials
• EgiAs coating reduces friction and extends cutting edge life
• 140-degree R-thinned point for self-centering entry and reduced thrust
• Coolant-through design compatible with internal coolant CNC setups
• Diameter tolerance of +0 to -0.018 mm for consistent hole sizing
• Two spiral flutes with tapered web for reliable chip evacuation

Compatibility

Designed for use in steel, alloy steel, cast iron, titanium, and titanium alloy workpieces across blind hole, cross hole, drilling, and self-centering applications; fits standard straight-cylindrical collets and chucks accepting a 4.00 mm shank diameter.

Installation Notes

This bit is intended for installation and use by trained machinists and CNC operators. Ensure the machine spindle and workpiece are fully secured before operation. When using coolant-through capability, confirm that coolant pressure and flow rate are appropriate for the machine setup and workpiece material. Solid carbide tooling is brittle — avoid lateral loading, interrupted cuts without proper feed reduction, or excessive runout in the collet or chuck.
