Osg 8670560 Screw Machine Drill Bit 5.60mm Carbide

Product Description

The OSG 8670560 is a solid carbide screw machine length drill bit designed for high-performance drilling in ferrous materials. Built to Series 6300 specifications, it features a 5.60mm diameter, a 140-degree split point, and a right-hand spiral flute with R-thinned web geometry. The straight-cylindrical shank provides secure chuck engagement. Solid carbide construction delivers the rigidity and wear resistance needed for production-rate drilling in steel, alloy steel, and cast iron. This bit is suited for machinists and tool and die professionals running CNC machining centers or manual drill presses where hole accuracy and tool life are priorities.

The 8670560 is intended for use in screw machine and short-hole drilling applications where a compact flute length and stiff tool body improve straightness and reduce deflection. Its 2xD flute-to-diameter ratio and tapered web configuration make it well-suited for drilling into steel, alloy steel, and cast iron in both job shop and production environments. The coated finish supports heat dissipation and extended cutting life under continuous use.

Key Features

• 5.60mm diameter with a diameter tolerance of +0 to -0.018mm for consistent hole sizing
• 140-degree drill point angle for self-centering entry and reduced thrust in hard materials
• Solid carbide construction for rigidity and wear resistance in ferrous workpieces
• R-thinned web with tapered web configuration reduces cutting forces at the chisel edge
• 2-flute regular spiral design promotes chip evacuation in screw machine length applications
• Straight-cylindrical shank compatible with standard drill chucks and collet holders

Compatibility

Designed as a high-performance screw machine length drill bit for use in steel, alloy steel, and cast iron workpieces. Consult OSG Series 6300 documentation for full application guidance.

Installation Notes

Installation and use of carbide drill bits should be performed by qualified machinists familiar with cutting tool setup and speeds and feeds selection. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Carbide is brittle — avoid lateral loading, interrupted cuts without proper parameters, or dropping the bit on hard surfaces. Follow the machine manufacturer and OSG Series 6300 recommendations for RPM and feed rate based on workpiece material.
