Product Overview

CNMM190624E-NR2 (short mark CNMM646-NR2) T9325 is a super-size double-sided negative rhombic heavy-duty turning insert developed by Pramet for extra heavy roughing of steel forgings and large structural steel parts. Equipped with NR2 ultra-wide heavy rough chipbreaker, E-type reinforced edge chamfer and reinforced R2.4 large nose radius, each insert delivers four durable cutting edges to lower per-part processing cost. Adopting T9325 high temperature resistant MT-CVD coating substrate, it perfectly matches MCLNR19 series heavy-duty external turning tool holders, supporting ultra-large depth of cut and high feed rate continuous & slight interrupted turning. Widely applied on heavy-duty CNC lathes and horizontal turning centers for heavy machinery, wind power, automotive forging and large mold mass metal processing1688阿....

Key Features
  • Super large IC19.05 size & 6.35mm ultra-thick substrate, outstanding rigidity to withstand ultra-heavy cutting load and strong impact force
  • Double-sided 80° rhombic negative structure, four usable cutting edges, higher cost efficiency than single-sided small-size inserts
  • E-type edge reinforced chamfer design, effectively prevent edge chipping during interrupted forging blank roughing
  • NR2 exclusive extra heavy wide-groove chipbreaker, oversized chip evacuation space, curls long steel chips into tiny stable fragments without winding
  • T9325 three-layer composite MT-CVD coating, thick aluminum oxide layer blocks cutting heat, greatly slow down flank and crater wear
  • Submicron gradient carbide base, balanced hardness and impact resistance, suitable for both continuous cutting and uneven forging intermittent machining
  • Dual international standard naming (metric CNMM190624 / inch shorthand CNMM646-NR2), convenient for global customer order inquiry and unified inventory management
  • Standard large positioning hole structure, high repeat indexing accuracy after edge replacement, stable dimensional tolerance for heavy batch production
