Osg 8673310 Carbide Jobber Drill Bit 13.1 Mm Egias

Product Description

The OSG 8673310 is a solid carbide jobber-length drill bit designed for precision hole-making in demanding machining applications. Ground to a 140-degree split point with R-thinned web geometry, it starts on contact and reduces thrust compared to conventional point angles. The 13.1 mm diameter cutting edge is paired with a 14 mm straight-cylindrical shank for secure chuck retention. An EgiAs coating provides elevated surface hardness and heat resistance, extending tool life when drilling steel, stainless, and other ferrous alloys. This bit is intended for use by machinists and tool-and-die professionals working on CNC machining centers, drill presses, and manual lathes requiring consistent, repeatable hole geometry.

The OSG 8673310 fits standard machining environments where a 13.1 mm diameter hole is required across a range of workpiece materials. Its 5xD flute-to-diameter ratio and 77 mm flute length accommodate moderate-depth drilling without chip packing. The straight-cylindrical shank allows mounting in standard drill chucks and collet systems sized for the 14 mm shank diameter. Typical applications include structural steel fabrication, mold-and-die work, and general-purpose production drilling where carbide hardness and coating durability are required over HSS alternatives.

Key Features

• Solid carbide construction for superior hardness and wear resistance versus high-speed steel
• EgiAs coating improves heat resistance and extends cutting tool life in ferrous materials
• 140-degree point angle reduces thrust and improves self-centering on entry
• R-thinned web minimizes walking and lowers feed force requirements
• Straight-cylindrical 14 mm shank compatible with standard drill chucks and collet holders
• Right-hand spiral flute design evacuates chips efficiently during through and blind-hole drilling

Compatibility

Designed as an OEM-specification solid carbide jobber-length drill bit suitable for use in standard drill chucks and collet systems accepting a 14 mm straight-cylindrical shank on CNC machining centers and drill presses.

Installation Notes

Installation and use should be performed by a qualified machinist familiar with cutting tool selection and machine setup. Secure the shank fully in the chuck or collet before operation and verify runout is within acceptable limits for the application. Always power down and lock out the machine spindle before changing or inspecting tooling. Follow the machine manufacturer and tooling manufacturer guidelines for feed rate and spindle speed when using carbide tooling to avoid chipping or premature tool failure.
