Product Selling Points
This MQR/L single-end profiling boring tool is forged from high-grade solid tungsten carbide with a matrix hardness of HRC92.6. It comes in both right and left-hand designs, machines bores above 2mm, and suits Swiss-type lathe precision machining.
Its 47° cutting edge with precision-ground R0.2 nose radius delivers accurate profiling contours and superior surface finish. The wear-resistant carbide maintains stable dimensional accuracy for continuous production of steel and stainless steel workpieces.
The high-rigidity shank ensures chatter-free stable performance in micro inner-bore machining. Prolonged tool life cuts tool-change downtime, greatly improving mass production efficiency of miniature precision metal parts.
