Osg 220-0938 Solid Carbide Jobber Drill Bit 3/32 Inch

Product Description

The OSG 220-0938 is a solid carbide jobber-length drill bit designed for precision drilling in a wide range of metalworking applications. It measures 3/32 inches (0.0938 inches decimal) in diameter with a 2-inch overall length and a 1-inch flute length. The 118-degree web-thinned point reduces thrust force and promotes self-centering on entry. The bright, uncoated finish is suited for applications where coating compatibility or post-treatment is a factor. With a straight-cylindrical shank and regular spiral flute geometry, this bit fits standard drill chucks and delivers consistent chip evacuation in general-purpose drilling tasks.

The 220-0938 is rated for drilling in steel, alloy steel, stainless steel, cast iron, aluminum, aluminum alloy, and aluminum silicate. It is well suited for blind hole and cross-hole drilling as well as through-hole and self-centering operations. The two-flute spiral design handles chip clearance effectively in both ferrous and non-ferrous materials. Machinists, tool-and-die technicians, and metalworking professionals working on precision components or production runs will find this bit appropriate for general-purpose small-diameter drilling where carbide rigidity is needed over high-speed steel alternatives.

Key Features

• Solid carbide construction provides rigidity and wear resistance for small-diameter drilling in hard materials
• 118-degree web-thinned point reduces entry thrust and supports self-centering
• Regular spiral, two-flute design promotes efficient chip evacuation
• Bright uncoated finish suitable for general-purpose use or where coating buildup must be avoided
• Straight-cylindrical shank fits standard drill chucks without adapters
• Series 220D rated for steel, stainless steel, cast iron, aluminum, and aluminum alloy workpieces

Compatibility

The OSG 220-0938 is compatible with primary workpiece materials coded P, M, K, and N, covering steel, alloy steel, stainless steel, cast iron, aluminum, aluminum alloy, and aluminum silicate. Designed as a general-purpose OEM-style replacement drill bit in the OSG 220D series for small-diameter carbide jobber-length applications.

Installation Notes

This bit is installed by machinists and metalworking technicians using standard drill presses, CNC machining centers, or handheld drill drivers with a compatible chuck accepting a 3/32-inch straight shank. Secure the shank fully in the chuck before operation and verify chuck runout is within tolerance, as carbide is brittle and susceptible to breakage from lateral loading. Coolant through is not supported on this bit; apply cutting fluid externally when drilling stainless steel or cast iron to manage heat and extend tool life. Inspect the point for chipping before each use, as micro-chipping on a carbide tip is not always visible without magnification.
