Product Uses
1.The MQR Internal Profile Boring Cutter features specialized profiling geometry that ensures precise duplication of complex internal contours, tapered bores, and radius transitions in single-pass operations .
2.Engineered with minimized shank diameter ΦA and optimized L1 overhang, the Micro profile boring bar accesses tight internal bores and extended depth cavities while maintaining adequate rigidity for precision contouring.
