Osg 8672700 Solid Carbide Jobber Drill Bit 7mm

Product Description

The OSG 8672700 is a solid carbide jobber length drill bit designed for high-performance drilling in ferrous materials. Built to Series 6310 specifications, it features a 140-degree R-thinned point for self-centering entry and reduced thrust on hard workpieces. The EgiAs coating improves wear resistance and heat dissipation during high-cycle production drilling. At 91 mm overall length with a 53 mm flute length and a 5xD flute-to-diameter ratio, this bit delivers consistent chip evacuation in blind hole and cross hole applications. It is suited for use by machinists, tool-and-die professionals, and maintenance technicians working with steel, alloy steel, and cast iron.

This drill bit is designed for demanding drilling operations including blind hole drilling, cross hole drilling, through drilling, and self-centering applications. Primary workpiece materials include steel, alloy steel, and cast iron, corresponding to material codes P, K, and H. The straight-cylindrical shank with an 8 mm shank diameter seats securely in standard drill chucks and collet holders on CNC machining centers, drill presses, and handheld drilling equipment. The regular spiral flute geometry and tapered web configuration support consistent performance at production feed and speed rates.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard ferrous materials
• 140-degree R-thinned point provides self-centering entry and reduces walking on hard surfaces
• EgiAs coating for improved heat and abrasion resistance during high-speed drilling
• 5xD flute-to-diameter ratio supports chip evacuation in deeper blind holes
• Two-flute spiral geometry with tapered web for consistent cutting performance
• Right-hand cut, straight-cylindrical shank compatible with standard chucks and collet systems

Compatibility

Designed as an OEM-style replacement and standard production drill bit for use with steel, alloy steel, and cast iron workpieces in CNC and manual drilling applications where a 7 mm diameter jobber length solid carbide bit is specified.

Installation Notes

Installation and use should be performed by a qualified machinist or tooling technician. Secure the straight-cylindrical shank firmly in a properly sized chuck or collet before operation to prevent runout. Ensure the spindle and workpiece are properly fixtured before initiating the cut. This bit does not support coolant-through delivery; use external coolant or cutting fluid appropriate for the workpiece material when required.
