Osg 8692370 Solid Carbide Jobber Drill 3.70 Mm 140 Deg

Product Description

The OSG 8692370 is a solid carbide jobber-length drill bit engineered for high-performance drilling in ferrous and hard materials. Measuring 3.70 mm in diameter with a 140-degree split point, it features an EgiAs coating that reduces friction and extends tool life under demanding cutting conditions. The R-thinned web design promotes self-centering entry and lowers thrust force, making it well suited for precision hole-making in production environments. Overall length is 86.00 mm with a 34.00 mm flute length and a 4.00 mm straight-cylindrical shank. This drill ships individually and is sold as a single unit.

This bit is designed for drilling into steel, alloy steel, cast iron, titanium, and titanium alloys, covering ISO material codes P, K, S, and H. It handles blind hole drilling, cross-hole drilling, and self-centering applications. The 5xD flute-to-diameter ratio and regular spiral geometry make it a reliable choice for CNC machining centers and precision manual drill presses where consistent chip evacuation is required. Coolant-through capability allows internal coolant delivery to the cutting zone for extended run times and tighter tolerances.

Key Features

• Solid carbide construction for rigidity and heat resistance in hard-material applications
• EgiAs coating reduces friction and improves wear resistance
• 140-degree R-thinned point promotes self-centering and reduces thrust force
• Coolant-through design supports internal coolant delivery for deep or high-speed drilling
• Right-hand spiral flute with regular helix for consistent chip evacuation
• Tapered web configuration adds strength at the core

Compatibility

Designed as an OSG Series 6510 replacement drill bit for applications involving steel, alloy steel, cast iron, titanium, and titanium alloys with a required hole diameter of 3.70 mm (0.1457 inch).

Installation Notes

Installation and use of carbide drill bits should be performed by qualified machinists or CNC operators familiar with proper toolholding and speed-and-feed selection. Secure the straight-cylindrical shank in a collet or drill chuck rated for the shank diameter before operation. Power down and de-energize the machine spindle completely before changing or inspecting tooling. Avoid side-loading carbide drills, as carbide is brittle and will fracture under lateral stress.
