Osg 15323005 Cobalt Jobber Drill Bit Letter P Tin

Product Description

The OSG 15323005 is a cobalt steel jobber-length drill bit in Letter P size (0.3230 inch / 8.20 mm diameter), finished with a Titanium Nitride (TiN) coating for extended tool life in ferrous materials. It features a 130-degree split point and a right-hand spiral flute with R-thinning at the web, which reduces entry force and centers the bit without a pilot hole. The straight-cylindrical shank measures 3/8 inch in diameter and fits standard drill chucks. Overall length is 5-1/8 inches with a flute length of 3-5/16 inches. This bit is part of the OSG Series 1500, a high-performance line built for productive drilling in steel and alloy steel applications.

This bit is suited for metalworking professionals, maintenance technicians, and machine shop operators drilling in steel and alloy steel workpieces. Typical applications include blind holes, cross holes, general drilling, and self-centering entry without a center drill. It is used in hand drills, drill presses, and CNC machining centers where a standard jobber length fits the work envelope. The 2-flute design handles chip evacuation efficiently in the ferrous materials this bit is rated for.

Compatibility

Designed for drilling in steel and alloy steel workpieces (primary workpiece material code P). The straight-cylindrical shank fits any standard drill chuck accepting 3/8-inch shanks.

Installation Notes

Installation is performed by machinists, metalworkers, or maintenance technicians using a drill press, hand drill, or CNC spindle. Secure the shank fully in the chuck and verify runout before drilling. Use appropriate cutting fluid or coolant when drilling steel at higher feed rates to protect the coating and extend tool life. Dispose of worn bits according to local shop safety procedures.
