TMR Round-nose T-slot External Turning Tool Bar R3 Series Slotting Three-sided Arc OEM Titanium Aluminum Nitride Coated
This R3-series TMR round nose T-slot milling arbor features a triple-edge arc cutting structure, purpose-built for CNC slotting and T-groove machining. Fabricated from high-strength hardened steel with precision machining, it delivers exceptional rigidity and stable cutting performance on standard CNC milling centers.
The R3 round nose profile creates smooth arc transitions at groove corners, eliminating sharp burrs and improving groove quality. The triple-edge configuration finishes the groove bottom and both side walls in a single pass, with optimized chip space for smooth chip evacuation, ensuring consistent dimensional accuracy and high machining efficiency.
Compatible with standard indexable inserts and CNC tool holders, this milling arbor is widely applied in mold making, machinery manufacturing, fixture production and metal fabrication. With reliable durability and low per-piece tooling cost, it offers a cost-effective solution for high-volume T-slot and arc groove machining tasks.
