Osg 220-0469 Solid Carbide Jobber Drill Bit 3/64 in

Product Description

The OSG 220-0469 is a solid carbide jobber-length drill bit designed for precision drilling in a wide range of metalworking and fabrication applications. It carries a 3/64 inch (0.0469 inch decimal) diameter with a 118-degree web-thinned point that promotes self-centering and reduces thrust on entry. The bright, uncoated finish maintains dimensional consistency straight from the tool grinder. At 1.5 inches overall length with a 0.75 inch spiral flute, this bit is built for tight-clearance work where a longer drill cannot fit. Right-hand cut with a regular spiral and straight-cylindrical shank, it seats directly into standard chucks and collets without modification.

This bit is suited for drilling blind holes, cross holes, and through-holes in steel, alloy steel, stainless steel, cast iron, aluminum, aluminum alloy, and aluminum silicate. The web-thinned, tapered web configuration reduces cutting resistance in harder materials, making it a practical choice for general-purpose metalworking in machine shops, maintenance facilities, and production environments. The 2-flute spiral design clears chips efficiently during short-stroke drilling cycles common with jobber-length bits.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous and non-ferrous metals
• 118-degree web-thinned point for self-centering entry and reduced axial thrust
• Bright uncoated finish — no coating buildup risk on tight-tolerance holes
• Right-hand cut, 2-flute regular spiral for efficient chip evacuation
• Straight-cylindrical shank fits standard drill chucks and collets
• Diameter tolerance of +0 to -0.013 mm for consistent hole sizing

Compatibility

Designed as a general-purpose jobber-length carbide drill bit in the OSG Series 220D, suited for use with standard drill presses, CNC machining centers, and hand-held power tools capable of accepting a 3/64 inch straight-cylindrical shank. Primary workpiece material codes: P, M, K, N.

Installation Notes

Installation and use of this drill bit should be performed by a qualified machinist or tool operator. Secure the shank fully in the chuck or collet and verify runout before engaging the workpiece. Power down and lock out the machine before changing bits or adjusting chuck position. Do not exceed the spindle speed and feed rate recommended by OSG for the workpiece material and bit diameter.
