Osg 8692290 Carbide Jobber Drill Bit 2.9 Mm 140 Deg

Product Description

The OSG 8692290 is a solid carbide jobber length drill bit designed for high-performance drilling in demanding metalworking applications. It measures 2.9 mm in diameter with an overall length of 78 mm and a flute length of 27 mm. The 140-degree R-thinned point reduces thrust force and promotes self-centering at the start of a cut. An EgiAs coating improves wear resistance and heat dissipation, making this bit well suited for production drilling in hard and abrasive materials. Machinists, tool-and-die shops, and precision fabricators install this type of tooling in CNC machining centers and drill presses.

This drill bit is rated for use in steel, alloy steel, cast iron, titanium, and titanium alloys, corresponding to ISO material codes P, K, S, and H. It supports blind hole drilling, cross-hole drilling, through-hole drilling, and self-centering applications. The 5xD flute-to-diameter ratio provides adequate chip evacuation in deeper holes. Coolant-through capability allows internal coolant delivery directly to the cutting edge, which extends tool life in high-speed or dry-cutting environments where heat buildup is a concern.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• EgiAs coating for improved thermal and abrasion resistance
• 140-degree R-thinned point for reduced thrust and self-centering entry
• Coolant-through design for internal coolant delivery to the cutting zone
• Two spiral flutes with regular helix for consistent chip evacuation
• Straight-cylindrical shank with 3.00 mm shank diameter for standard collet and chuck compatibility

Compatibility

Designed as an OEM-style replacement or production tooling option within the OSG Series 6510 drill line, suitable for use in standard collet chucks and drill chucks accepting a 3.00 mm straight-cylindrical shank.

Installation Notes

This tooling is installed by machinists and tooling technicians in CNC machining centers, drill presses, and multi-spindle setups. Ensure the machine spindle is fully stopped and locked out before changing tooling. Confirm the collet or chuck bore matches the 3.00 mm shank diameter and that runout is within acceptable limits before beginning a cutting operation. When using coolant-through capability, verify the machine spindle is rated for internal coolant delivery at the required pressure.
