Osg 220-1800 Jobber Drill Bit Wire 15 Solid Carbide

Product Description

The OSG 220-1800 is a jobber-length drill bit from the Series 220D line, designed for precision drilling in metalworking and machining applications. It is manufactured from solid carbide with a bright, uncoated finish and features a 118-degree web-thinned point for accurate self-centering on entry. The bit measures 2.75 inches overall length with a 1.625-inch flute length, has a straight-cylindrical shank, and a two-flute spiral configuration with a right-hand cutting direction. Wire size 15 corresponds to a decimal diameter of 0.1800 inches. General-purpose tooling, installed by machinists and tool room technicians on drill presses, CNC machining centers, and handheld power tools.

The 220-1800 is suited for drilling blind holes, cross holes, and through holes in a wide range of workpiece materials. Primary workpiece compatibility includes steel, alloy steel, stainless steel, cast iron, aluminum, aluminum alloy, and aluminum silicate. The web-thinned point geometry reduces thrust load and improves centering without a separate spotting operation. Regular spiral geometry promotes efficient chip evacuation during standard drilling cycles. This bit fits general-purpose production and maintenance drilling tasks where solid carbide performance is required over high-speed steel alternatives.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous and non-ferrous materials
• 118-degree web-thinned point for reduced entry thrust and self-centering capability
• Bright uncoated finish suitable for general-purpose drilling without coating-related buildup concerns
• Right-hand cut, two-flute spiral design for efficient chip evacuation
• Straight-cylindrical shank compatible with standard drill chucks and collet holders
• Wire size 15 decimal equivalent 0.1800 inches with a tight diameter tolerance of plus 0 to minus 0.013 mm

Compatibility

Designed for use in standard drill chucks, collet-style toolholders, and CNC spindles accepting a straight-cylindrical shank. Compatible workpiece materials include steel, alloy steel, stainless steel, cast iron, aluminum, aluminum alloy, and aluminum silicate. Part of the OSG Series 220D jobber-length solid carbide drill family covering the 0.1500 to 0.2000 inch decimal inch size range.

Installation Notes

Install in a clean, properly sized drill chuck or collet holder and verify runout before drilling. Solid carbide tooling is brittle compared to high-speed steel; avoid side loading, interrupted cuts without proper feed control, or dropping the bit, as chipping can result. Coolant-through is not supported on this bit; apply external coolant or cutting fluid appropriate to the workpiece material when drilling stainless steel, alloy steel, or cast iron. Confirm spindle speed and feed rate are appropriate for a 0.1800-inch carbide drill in the target material before beginning production runs.
