Osg 8672670 Solid Carbide Jobber Drill Bit 6.7 Mm

Product Description

The OSG 8672670 is a solid carbide jobber-length drill bit designed for high-performance drilling in ferrous materials. It measures 6.7 mm in diameter (0.2638 inches decimal equivalent) with a 140-degree R-thinned point that promotes self-centering and reduces thrust on entry. The EgiAs coating improves wear resistance and heat dissipation at the cutting edge. At 91 mm overall length with a 53 mm flute length, this bit falls in the standard jobber range and is sized for use in CNC machining centers, drill presses, and manual machines where a straight-cylindrical shank is required. It is installed and operated by machinists and tool and die professionals.

The OSG 8672670 is suited for drilling blind holes, cross holes, and through-hole applications in steel, alloy steel, and cast iron. The 5xD flute-to-diameter ratio supports chip evacuation in moderate-depth holes. The regular spiral and tapered web configuration make it a practical general-purpose carbide bit for production and maintenance machining environments where consistent hole quality in hard ferrous workpieces is required. It is sold individually.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous materials
• EgiAs coating for extended tool life and improved cutting performance
• 140-degree R-thinned point promotes self-centering and reduces walking on entry
• Right-hand spiral flute with regular helix for reliable chip evacuation
• Straight-cylindrical shank at 8 mm diameter fits standard collets and chucks
• Suitable for blind hole, cross hole, and self-centering drilling applications

Compatibility

Designed for use in steel, alloy steel, and cast iron workpieces (material codes P, K, H). Compatible with any machine tool holding a straight-cylindrical shank at 8 mm diameter, including CNC machining centers and manual drill presses equipped with appropriate collet or drill chuck.

Installation Notes

Secure the straight-cylindrical shank firmly in a collet or keyed chuck rated for the spindle speed appropriate to carbide tooling in the workpiece material. Carbide is brittle — avoid side loading or using this bit to ream or pry. Confirm machine runout is within tolerance before use, as excessive runout accelerates carbide edge chipping. This bit does not support coolant-through delivery; apply external coolant or cutting fluid as required by the application.
