Osg 8692230 Solid Carbide Jobber Drill 2.30mm 140 Deg

Product Description

The OSG 8692230 is a solid carbide jobber-length drill bit designed for high-performance drilling in demanding metalworking applications. It features a 2.30 mm diameter, a 140-degree R-thinned point for self-centering entry, and an EgiAs coating engineered to extend tool life and reduce heat buildup at the cutting edge. The overall length is 70.00 mm with a 21.00 mm flute length, and the straight-cylindrical shank measures 3.00 mm in diameter. Two spiral flutes in a regular helix geometry provide efficient chip evacuation. This drill is built for machinists and toolroom professionals running production or precision work on CNC and manual equipment.

The 8692230 is suited for drilling blind holes, cross holes, and through holes in steel, alloy steel, cast iron, titanium, and titanium alloys — covering ISO material groups P, K, S, and H. The 5xD flute-to-diameter ratio makes it appropriate for moderate-depth drilling without specialized toolholding. Coolant-through capability supports high-feed applications where internal coolant delivery is available, helping to manage chip load and thermal stress at depth. It is well matched for precision component manufacturing, mold and die work, and aerospace or automotive part production where tight hole tolerances are required.

Key Features

• EgiAs coating reduces friction and thermal wear in hard and abrasive workpiece materials
• 140-degree R-thinned point geometry promotes self-centering and reduces thrust force at entry
• Coolant-through design supports high-feed drilling with internal coolant supply
• Solid carbide construction provides rigidity and edge retention in ferrous and exotic alloys
• Straight-cylindrical shank fits standard drill chucks and collet toolholders
• Diameter tolerance of +0 to -0.014 mm supports close-tolerance hole production

Compatibility

Designed as an OEM-style replacement or direct-use drill for applications requiring a 2.30 mm solid carbide jobber drill in the OSG Series 6510 product family, compatible with standard straight-shank toolholders and collets accepting a 3.00 mm shank diameter.

Installation Notes

Installation and use should be performed by qualified machinists or tool-and-die professionals familiar with carbide tooling. Secure the straight-cylindrical shank in a properly sized collet or drill chuck, ensuring full shank engagement before running the spindle. Carbide drills are brittle compared to high-speed steel — avoid side loads, interrupted cuts without appropriate feed reduction, and contact with hardened surfaces that exceed the tool's rated material range. When using the coolant-through feature, verify that coolant pressure and flow rate are compatible with the machine spindle before operation.
