Osg 8692710 Carbide Jobber Drill Bit 7.1mm 140 Deg

Product Description

The OSG 8692710 is a solid carbide jobber length drill bit designed for precision drilling in hard and abrasive materials. It features a 7.1 mm diameter, a 140-degree split point angle, and an EgiAs coating that extends tool life by reducing friction and heat buildup at the cutting edge. The overall length is 118 mm (approximately 4.65 inches) with a 57 mm flute length. An X-thinned web reduces thrust requirements and improves chip evacuation. This bit is used by machinists, tool and die professionals, and metalworking tradespeople in production and maintenance drilling applications.

This drill bit suits applications requiring tight-tolerance holes in hardened steels, stainless alloys, cast iron, and other difficult-to-machine materials. The 5xD flute-to-diameter ratio provides adequate chip clearance in moderate-depth holes. Coolant-through capability makes it compatible with CNC machining centers and other spindle equipment equipped with internal coolant delivery. It is sized for use in standard drill chucks or collet systems accepting an 8 mm straight-cylindrical shank.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• 140-degree point angle for self-centering entry and reduced walking on flat surfaces
• EgiAs coating reduces friction and extends cutting life
• Coolant-through design supports internal coolant delivery for deep-hole and high-speed applications
• X-thinned web lowers thrust force and improves chip flow
• Right-hand spiral flute with straight-cylindrical 8 mm shank for standard chuck and collet compatibility

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide jobber drill for CNC machining centers, drill presses, and manual machines equipped with collet chucks or drill chucks accepting an 8 mm straight shank.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or metalworking professionals familiar with carbide tooling. Ensure the spindle and chuck or collet are clean and within tolerance before seating the shank. Carbide is brittle — avoid side loads, interrupted cuts without appropriate feed adjustments, or impact-style drivers. When using coolant-through capability, verify that coolant pressure and flow rate are within the machine and toolholder specifications before running at full speed.
