Osg 220-1695 Solid Carbide Jobber Drill Bit No. 18

Product Description

The OSG 220-1695 is a solid carbide jobber-length drill bit in the Series 220D, designed for precise, general-purpose drilling in metalworking applications. It carries a Number 18 wire gauge size (0.1695 inch / 4.31 mm diameter) and features a 118-degree point angle with web-thinned geometry for improved self-centering and reduced thrust on entry. The bright, uncoated finish maintains a sharp cutting edge without added coating thickness. At 2.75 inches overall length with a 1.625-inch flute length, it fits standard drill chucks and machines used in production and maintenance environments. Licensed HVAC, mechanical, and fabrication tradespeople reach for this bit when drilling through ferrous and non-ferrous stock to tight tolerances.

The OSG 220-1695 is suited for drilling blind holes, cross holes, and through holes in a wide range of workpiece materials. Its spiral flute design promotes chip evacuation in steel, alloy steel, stainless steel, cast iron, aluminum, aluminum alloy, and aluminum silicate. The two-flute, right-hand-cut configuration and straight cylindrical shank make it compatible with standard drill presses, CNC machining centers, and hand-held power tools. It is positioned for general-purpose use where solid carbide rigidity is required for dimensional accuracy.

Key Features

• Solid carbide construction provides rigidity and wear resistance compared to high-speed steel alternatives
• 118-degree web-thinned point improves self-centering and reduces required thrust at entry
• Bright, uncoated finish — no coating thickness variation affecting hole diameter tolerance
• Diameter tolerance of +0 to -0.013 mm supports consistent, repeatable hole sizing
• Spiral flute with tapered web configuration promotes chip clearing in both ferrous and non-ferrous materials
• Right-hand cut, straight cylindrical shank — compatible with standard collets and three-jaw chucks

Compatibility

Designed for use in steel, alloy steel, stainless steel, cast iron, aluminum, aluminum alloy, and aluminum silicate workpieces. Suitable for blind hole, cross hole, through-hole drilling, and self-centering applications across general-purpose machining and fabrication setups.

Installation Notes

Install this bit in a drill press, CNC spindle, or hand-held drill with a chuck rated for the straight cylindrical shank diameter. Secure the shank fully in the chuck or collet before operation to prevent runout. Power down and lock out the machine before changing or inspecting bits. Follow the machine manufacturer and applicable shop safety standards for speeds, feeds, and coolant when drilling carbide tooling.
