Osg HP245-3465 Jobber Drill Bit 0.3465 in Solid Carbide

Product Description

The OSG HP245-3465 is a solid carbide jobber-length drill bit designed for precision drilling in demanding production environments. Sized at 0.3465 inches (8.80 mm) in diameter, it features a 140-degree split point for accurate self-centering and reduced walking on entry. The WD1 coating provides enhanced wear resistance and heat dissipation during high-speed cutting operations. With an overall length of 103.00 mm and a flute length of 61.00 mm, this bit falls within the standard jobber-length profile. It is intended for use by machinists, tool-and-die professionals, and CNC operators working with ferrous and non-ferrous materials.

This drill bit is suited for general-purpose and production drilling applications in machine shops, manufacturing facilities, and metalworking environments. The 5xD flute-to-diameter ratio and R-thinned web geometry support efficient chip evacuation in through-hole and blind-hole operations. The 10.00 mm shank diameter is compatible with standard drill chucks and collet systems. Coolant-through capability is not included on this model, so external flood or mist coolant is recommended for deep or high-feed drilling cycles.

Key Features

• Solid carbide construction for rigidity and extended tool life in hard materials
• 140-degree drill point angle promotes self-centering and minimizes thrust force
• WD1 coating improves surface hardness and reduces built-up edge
• R-thinned web reduces cutting resistance at the chisel edge
• 5xD flute ratio supports effective chip removal in deeper holes
• Diameter tolerance of +0.0060 to +0.0210 mm for consistent hole sizing

Compatibility

Designed for use in standard drill chucks and collet holders accepting a 10.00 mm shank, suitable for CNC machining centers and manual drill presses used in metalworking and production machining applications.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or CNC operators familiar with tooling setup and speeds-and-feeds calculations. Ensure the spindle is fully stopped and the machine is powered down or in a safe state before loading or changing the bit. Secure the shank firmly in the chuck or collet to the full recommended engagement depth to prevent pullout under load. External coolant is recommended since this model does not include coolant-through capability.
