Osg 220-2010 Solid Carbide Jobber Drill Bit No. 7

Product Description

The OSG 220-2010 is a solid carbide jobber-length drill bit in the Series 220D, sized to wire gauge No. 7 (0.2010 inches / 5.11 mm decimal equivalent). It features a 118-degree web-thinned point, a bright uncoated finish, and a straight-cylindrical shank. The two-flute spiral design provides efficient chip evacuation during general-purpose drilling operations. With an overall length of 3 inches and a flute length of 1.75 inches, this bit suits production and maintenance drilling in metalworking environments. It is installed by machinists, tool-and-die technicians, and maintenance mechanics working with drill presses, CNC machining centers, and hand-held power tools.

This bit is built for drilling into a wide range of workpiece materials including steel, alloy steel, stainless steel, cast iron, aluminum, aluminum alloy, and aluminum silicate. Typical applications include blind hole drilling, cross-hole drilling, through drilling, and self-centering operations. The web-thinned point reduces thrust requirements and improves self-centering performance, making it effective for tight-tolerance work in both job-shop and production settings. The solid carbide construction supports use at higher surface speeds compared to high-speed steel alternatives, which is advantageous when drilling harder or abrasive materials.

Key Features

• Solid carbide construction for durability and heat resistance in metalworking applications
• 118-degree web-thinned point with tapered web configuration for reduced thrust and improved self-centering
• Bright uncoated finish suitable for general-purpose use across a broad range of metals
• Two-flute regular spiral design promotes chip flow and helps maintain cutting efficiency
• Straight-cylindrical shank compatible with standard drill chucks and collet systems
• Diameter tolerance of +0 to -0.013 mm for consistent hole sizing

Compatibility

Designed as an OEM-style general-purpose jobber drill bit compatible with standard straight-shank drill chucks and collet holders accepting a 7.00 mm shank diameter. Suitable for use in drill presses, CNC machining centers, and portable power drills configured for solid carbide tooling.

Installation Notes

Installation and setup should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Secure the straight-cylindrical shank firmly in a compatible chuck or collet to the manufacturer-specified holding depth to prevent runout. Solid carbide bits are brittle compared to high-speed steel — avoid side-loading, interrupted cuts beyond designed application, or using the bit as a reamer, as this can cause chipping or fracture.
