Osg 8692720 Carbide Jobber Drill Bit 7.2 Mm 140 Deg

Product Description

The OSG 8692720 is a solid carbide jobber-length drill bit engineered for high-performance drilling in ferrous and hard-alloy materials. It measures 7.2 mm in diameter (0.2835 inches decimal equivalent) with a 140-degree drill point angle and an overall length of 118 mm (approximately 4.65 inches). The EgiAs coating reduces friction and extends tool life in demanding applications. A right-hand spiral flute design with R-thinned point geometry promotes accurate self-centering entry and efficient chip evacuation. Coolant-through capability makes it suitable for deep-hole work where heat buildup is a concern. Machinists and tool-and-die professionals are the primary users.

The OSG 8692720 is rated for use on steel, alloy steel, cast iron, titanium, and titanium alloys (ISO material codes P, K, S, and H). It is built for blind holes, cross holes, standard through drilling, and self-centering applications. The 5xD flute-by-diameter ratio supports stable chip flow at extended depths. This bit fits applications in precision machining, aerospace component work, and heavy industrial fabrication where tight diameter tolerances and tool longevity are required.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard workpiece materials
• EgiAs coating for reduced friction and extended tool life
• 140-degree drill point with R-thinned web geometry for accurate self-centering entry
• Coolant-through design supports heat management in blind and deep-hole drilling
• Right-hand, regular spiral flute with 5xD ratio for consistent chip evacuation
• Straight-cylindrical shank with 8 mm shank diameter for broad chuck compatibility

Compatibility

Part of the OSG Series 6510 product line, designed for drilling steel, alloy steel, cast iron, titanium, and titanium alloys. Suitable for CNC machining centers and drill presses equipped with chucks or collets accepting an 8 mm straight shank.

Installation Notes

Installation and tool changes should be performed with the machine powered down and spindle fully stopped. Secure the straight-cylindrical shank in a properly sized collet or drill chuck, ensuring full shank engagement before operation. Coolant-through setups require compatible toolholders and a machine spindle that supports internal coolant delivery. Follow the machine manufacturer guidelines and applicable shop safety standards when setting feeds, speeds, and coolant flow rates.
