Carmex MTR4R0.2L15 Boring Bar Solid Carbide Right Hand

Product Description

The CARMEX MTR4R0.2L15 is a solid carbide boring bar designed for internal turning and bore finishing operations on CNC lathes and boring machines. It features a right-hand cutting direction, a minimum bore diameter of 0.16 inches, and a corner radius of 0.008 inches, making it well suited for tight-tolerance finish passes in small-diameter bores. The overall length is 2 inches and the shank diameter is 4 millimeters. Solid carbide construction provides rigidity and vibration resistance in small-bore applications where tool deflection must be minimized. A bright finish coating is applied to the tool body.

This boring bar is used in precision machining environments including job shops, production turning cells, and toolroom operations. It is intended for right-hand internal boring on CNC turning centers and manual lathes equipped with appropriate toolholding for 4 mm shank tooling. Typical applications include bore finishing, diameter correction, and internal profile work in ferrous and non-ferrous materials. The 0.59-inch maximum bore depth and compact geometry make it appropriate for shallow, small-diameter bore work where clearance is limited.

Key Features

• Solid carbide construction for rigidity and reduced deflection in small-bore applications
• Minimum bore diameter of 0.16 inches for tight, small-diameter internal work
• Right-hand cutting direction for standard CNC turning center setups
• 0.008-inch corner radius for controlled surface finish and edge geometry
• Bright finish coating on tool body
• Compact 2-inch overall length suits short-reach boring applications

Compatibility

Designed for use in toolholders accepting a 4 mm shank diameter boring bar, as found on CNC turning centers and manual lathes configured for small-shank internal tooling.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and the control is in an e-stop or locked-out state before loading or adjusting tooling. Confirm shank seating depth and tool overhang comply with the toolholder manufacturer's recommendations to minimize deflection. Verify bore depth and diameter parameters against the workpiece drawing before initiating a cut.
