MQR Carbide Micro Profiling & Boring Bar Overview<\/h2>\n
\n

MQR Series solid carbide micro profiling and boring bars are designed for complex internal contouring, precision boring, chamfering and shoulder machining inside small-diameter bores. The standard range covers actual cutting diameters from \u00d82.9 mm to \u00d87.9 mm and tip radii from R0.05 mm to R0.40 mm.<\/p>\n

The 47\u00b0 profiling geometry provides additional access for compound internal features and profile transitions. Its one-piece fine-grain solid carbide construction helps limit deflection and supports stable dimensional accuracy during CNC and Swiss-type small-parts machining.<\/p>\n<\/section>\n
