Osg 8672230 Solid Carbide Jobber Drill Bit 2.3 Mm

Product Description

The OSG 8672230 is a solid carbide jobber-length drill bit designed for high-performance drilling in ferrous materials. It measures 2.3 mm in diameter with an overall length of 66 mm and a flute length of 20 mm. The 140-degree X-thinned point promotes self-centering and reduces thrust when entering the workpiece. An EgiAs coating improves wear resistance and heat dissipation during cutting. The straight-cylindrical shank measures 4 mm in diameter for secure chuck retention. This bit is intended for use by machinists, toolroom technicians, and precision fabricators working with CNC or manual drilling equipment.

The 8672230 is built for drilling steel, alloy steel, and cast iron in production and job-shop environments. It handles blind hole, cross hole, and standard through-hole drilling applications. The 5xD flute-to-diameter ratio and regular spiral geometry support efficient chip evacuation in these materials. The tapered web configuration paired with X-thinned point geometry reduces walking and improves entry accuracy without a center punch in many setups. This bit fits into the OSG Series 6310 product family of high-performance carbide drills.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous materials
• 140-degree X-thinned point for self-centering entry and reduced thrust
• EgiAs coating for improved heat and abrasion resistance
• 2-flute spiral design with 5xD flute ratio for efficient chip removal
• Straight-cylindrical 4 mm shank for standard chuck compatibility
• Diameter tolerance of plus 0 to minus 0.014 mm for close-tolerance hole work

Compatibility

Designed for use in steel, alloy steel, and cast iron workpieces; suitable for blind hole, cross hole, standard drilling, and self-centering applications as part of the OSG Series 6310 carbide drill line.

Installation Notes

Installation and use of this bit should be performed by qualified machinists or toolroom technicians familiar with carbide cutting tools. Secure the straight-cylindrical shank firmly in a collet or drill chuck rated for the spindle speed required by the workpiece material. Carbide is brittle — avoid side-loading or using this bit in a handheld drill. Confirm spindle runout is within acceptable limits before use to prevent premature chipping or breakage.
