Widia 2836593 Boring Bar Submicron Solid Carbide Abd

Product Description

The WIDIA 2836593 is a submicron solid carbide boring bar designed for precision internal boring operations in tight-tolerance machining applications. Built to the ABD series standard, it features a right-hand cutting direction and a minimum bore diameter of 0.125 inches, making it well-suited for small-diameter bores where rigidity and surface finish are critical. The overall length is 1.025 inches, with a shank diameter of 5/32 inches and a bar neck diameter of 9/64 inches. Machinists and toolroom technicians working on CNC lathes or boring mills will find this bar appropriate for finishing and semi-finishing passes in challenging materials.

This boring bar is intended for use in metal cutting operations involving steel, stainless steel, cast iron, and non-ferrous metals. The submicron carbide grade provides the wear resistance needed for both ferrous and non-ferrous applications. With a maximum bore depth of 3/8 inches and a projection of 0.375 inches, it is best applied to shallow, small-bore features where tool overhang must be minimized to maintain accuracy and chatter resistance. It fits standard toolholders accepting a 5/32-inch shank.

Key Features

• Submicron solid carbide construction for enhanced wear resistance and edge stability
• Right-hand cutting direction for conventional boring setups
• Minimum bore diameter of 0.125 inches for small-diameter internal features
• Maximum bore depth of 0.375 inches limits overhang and supports rigidity
• ABD series designation for consistent toolholder compatibility
• Suitable for steel, stainless steel, cast iron, and non-ferrous metals

Compatibility

Designed for use in toolholding systems that accept a 5/32-inch shank diameter boring bar. Part of the WIDIA ABD series.

Installation Notes

Installation should be performed by a qualified machinist with the machine powered down and all axes at rest before tool changes. Secure the shank fully within the toolholder to the recommended grip depth to minimize deflection at small bore diameters. Verify bore diameter and depth clearances before starting the cut. Follow the machine manufacturer and shop safety procedures when handling carbide tooling.
