NIC positions MH as its alternative for EdgeFile X7 users — a constant-taper .04/.06 range extended to size 45 in MaxTech High Flex CM-class wire, documented by the manufacturer's fact sheet, draft IFU, and catalog (300-500 RPM / 3.0 Ncm per the 2026-08 fact sheet). Choose EdgeFile X7 for the studied original with published FireWire heat treatment and independent fatigue data.
