Osg 8693000 Solid Carbide Jobber Drill Bit 10 Mm

Product Description

The OSG 8693000 is a solid carbide jobber-length drill bit designed for high-performance drilling in hard and abrasive workpiece materials. It carries a 10 mm diameter with a 140-degree split point and an R-thinned web, which reduces thrust and promotes self-centering at the entry point. The EgiAs coating improves wear resistance and heat dissipation during aggressive cutting cycles. Overall length is 136 mm with an 80 mm flute length, giving it a 5xD flute-to-diameter ratio suited for moderate-depth hole applications. A straight-cylindrical shank seats directly in standard drill chucks or collet toolholders. Licensed machinists, tool-and-die makers, and CNC setup technicians are the primary users.

This bit is rated for drilling steel, alloy steel, cast iron, titanium, and titanium alloy — material codes P, K, S, and H. Typical applications include blind hole drilling, cross-hole operations, and self-centering entry in production environments where coolant-through delivery is available. The 2-flute spiral configuration with a regular helix handles chip evacuation in these materials without packing. It is part of OSG Series 6510, a line positioned for high-performance metal cutting on CNC machining centers and drill presses running coolant.

Key Features

• Solid carbide construction for rigidity and wear life in hard ferrous and exotic alloy materials
• EgiAs coating reduces friction and extends tool life in steel and titanium applications
• 140-degree point angle with R-thinned web for self-centering and reduced entry thrust
• Coolant-through capability supports high-feed drilling and chip flushing in blind holes
• 5xD flute-to-diameter ratio balances flute strength with chip clearance in moderate-depth applications
• Straight-cylindrical shank compatible with standard ER collets and drill chucks

Compatibility

Designed for use in CNC machining centers, drill presses, and multi-axis machines capable of coolant-through delivery. Suitable for workpiece materials classified under ISO material codes P (steel), K (cast iron), S (titanium and superalloys), and H (hardened materials). Compatible with standard 10 mm ER collet toolholders and drill chucks.

Installation Notes

Install in a clean, properly sized collet or drill chuck and verify runout before beginning a production run, as carbide is sensitive to lateral loading from excessive runout. Engage coolant-through flow before the tool contacts the workpiece to prevent thermal shock to the carbide substrate. Follow machine tool manufacturer guidelines for spindle speed and feed rate when drilling titanium or hardened steel, as carbide tools require rigid setups with minimal vibration. Do not use this bit in hammer-drill or impact-driver mode.
