Osg 8672510 Solid Carbide Jobber Drill Bit 5.1mm

Product Description

The OSG 8672510 is a solid carbide jobber-length drill bit designed for high-performance drilling in ferrous materials. It runs a 5.1 mm diameter with a 140-degree R-thinned point that reduces thrust and enables self-centering entry. The EgiAs coating improves wear resistance and heat dissipation in demanding cutting conditions. Overall length is 82 mm with a 44 mm flute length and a 6 mm straight-cylindrical shank. The 2-flute spiral geometry with tapered web configuration supports consistent chip evacuation in blind hole, cross hole, and through-drilling operations. This bit is aimed at machinists and toolroom technicians working in production or maintenance environments.

The OSG 8672510 is suited for drilling steel, alloy steel, and cast iron workpieces. The 5xD flute-to-diameter ratio makes it a practical choice for moderate-depth blind holes and cross holes in these material categories. Right-hand cut geometry pairs with standard clockwise spindle rotation on CNC machining centers, drill presses, and manual lathes. The straight-cylindrical shank fits standard drill chucks and collet holders sized for 6 mm shanks. It is used in both job-shop and production settings where dimensional accuracy and tool life in hard ferrous stock are priorities.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous materials
• EgiAs coating enhances surface hardness and reduces heat buildup at the cutting edge
• 140-degree R-thinned point promotes self-centering and lowers entry thrust
• 2-flute regular spiral with tapered web for efficient chip evacuation
• 5xD flute ratio supports blind hole and cross hole applications
• Diameter tolerance held to +0 to -0.018 mm for close-tolerance work

Compatibility

Part of OSG Series 6310. Designed for use in steel, alloy steel, and cast iron workpieces. Fits standard 6 mm straight-cylindrical shank drill chucks and collet holders.

Installation Notes

Installation and operation should be performed by qualified machinists familiar with cutting tool setup and machine tool operation. Ensure the spindle is fully stopped and the machine is locked out before inserting or removing the bit from the chuck or collet. Verify chuck or collet concentricity before use, as runout accelerates carbide wear and can cause premature breakage. Do not use this bit with coolant-through setups, as this tool does not support internal coolant delivery.
