MNR Carbide Micro Boring Bar | Small-Hole Boring, Grooving & Threading Cutter

MNR Carbide Micro Boring Bar

Solid-carbide micro boring bar for small-hole internal machining, including boring, grooving, profiling and selected threading operations depending on the chosen geometry.

Key Features

• Designed for precision work in small bores; suitable sizes can machine holes from approximately 2.1 mm.
• Solid-carbide construction provides rigidity and wear resistance at small tool diameters.
• Multiple shank diameters, nose radii and cutting lengths are available for different bore sizes and reach requirements.
• Series options cover boring, grooving, profiling and 55° / 60° internal threading geometries where specified.

Selection

Select the required MNR shank size, nose radius and cutting length from the variant menu. Confirm minimum bore diameter, feature geometry and required reach before ordering, and keep tool overhang as short as practical.
