Osg 8667230 Solid Carbide Jobber Drill Bit 2.3 Mm

Product Description

The OSG 8667230 is a solid carbide jobber-length drill bit designed for high-performance drilling in demanding industrial and machining applications. Built to Series 5210 specifications, it features a 2.3 mm diameter, a 140-degree drill point angle for reduced thrust and self-centering on entry, and a WXL coating that extends tool life in abrasive and high-heat cutting conditions. The straight-cylindrical shank measures 3.0 mm in diameter, seating securely in standard collet chucks and drill chucks. This bit is suited for CNC machining centers, manual mills, and benchtop drill presses where tight tolerances and consistent hole quality are required.

The 8667230 is intended for use in precision metalworking and manufacturing environments. Its 5xD flute-to-diameter ratio and 21 mm flute length make it well suited for through-hole and blind-hole drilling in ferrous metals, stainless steels, cast iron, and certain superalloys, corresponding to workpiece material codes P, M, K, and S. With an overall length of 70 mm, it fits standard tooling setups without requiring extended-reach adapters. Machinists, toolroom technicians, and production line operators working with small-diameter precision holes will find this bit a direct-fit solution for Series 5210 tooling programs.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• WXL coating reduces friction and heat buildup, extending cutting life
• 140-degree split point angle minimizes walking and reduces entry thrust
• Right-hand spiral flute with regular helix promotes efficient chip evacuation
• Coolant-through capability supports high-speed, deep-hole drilling cycles
• Diameter tolerance of +0 to -0.014 mm ensures consistent, repeatable hole sizing

Compatibility

Designed as a Series 5210 jobber-length drill bit for use in workpiece materials classified under P (steel), M (stainless steel), K (cast iron), and S (superalloys and titanium) per ISO material group designations.

Installation Notes

Installation and use should be performed by qualified machinists or toolroom technicians familiar with carbide tooling. Secure the straight-cylindrical shank firmly in a properly sized collet or drill chuck before operation, and verify runout before cutting. Carbide tooling is brittle — avoid side loads, interrupted cuts without proper feed rate adjustments, and hand-feed applications where torque control is limited. When using the coolant-through feature, confirm coolant pressure and flow rate are compatible with the machine spindle before starting the cycle.
