Osg 220-0595 Solid Carbide Jobber Drill Bit No. 53

Product Description

The OSG 220-0595 is a solid carbide jobber length drill bit designed for precision drilling in metalworking applications. Built to Series 220D specifications, it features a 118-degree web-thinned point angle and a right-hand spiral flute configuration that promotes efficient chip evacuation and self-centering entry. The bit measures 1.5 inches overall length with a 0.75 inch flute length, and corresponds to No. 53 wire gauge size, equivalent to 0.0595 inches (1.51 mm) in diameter. It ships bright and uncoated, making it well suited for general-purpose drilling in a wide range of materials. Licensed HVAC, plumbing, and electrical tradespeople as well as industrial machinists will find this bit appropriate for blind hole, cross hole, and standard through-hole operations.

This drill bit is engineered for use across a broad range of workpiece materials including steel, alloy steel, stainless steel, cast iron, aluminum, aluminum alloy, and aluminum silicate. Its tapered web configuration and web-thinned point reduce thrust load at entry, making it effective in both manual hand drill and CNC drilling center applications. It is intended for general-purpose production and maintenance drilling where tight diameter tolerance and consistent hole quality are required.

Key Features

• Solid carbide construction for hardness and wear resistance in metalworking applications
• 118-degree web-thinned point with tapered web for reduced entry thrust and self-centering performance
• Right-hand regular spiral flute for efficient chip evacuation in blind and through holes
• No. 53 wire gauge diameter (0.0595 inches / 1.51 mm) with tight tolerance of +0 to -0.013 mm
• Bright/uncoated finish compatible with a wide variety of materials including ferrous and non-ferrous metals
• Straight-cylindrical shank for use in standard drill chucks and collet holders

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, standard drilling, and self-centering applications across general-purpose machining environments.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or tradespeople familiar with drill press, hand drill, or CNC equipment operation. Ensure the drill chuck or collet is properly tightened around the straight-cylindrical shank before operation. Appropriate cutting fluid or coolant should be considered for ferrous materials to manage heat, even though this bit does not feature coolant-through capability. Always follow applicable shop safety protocols and equipment manufacturer guidelines when selecting spindle speed and feed rate.
