Radius cutter for profile milling of complex parts
Upgraded FixRMill round insert copy mill with unique anti-rotation system
Applications & Features
Applications
Features
1. Accurate and secure clamping
- The anti-rotation system securely keeps the inserts locked in place and prevents them from moving in the pockets during machining, ensuring tool reliability and accurate indexing over various applications.
- High productive cutter with close pitch design

2. Two types of inserts
- Both inserts can be clamped in the same pocket
- Inserts can be selected based on the required depth of cut for best cost per edge
RQMT1204ENC8-MM
Allows up to 8 indexes for 1.4 mm or smaller D.O.C. and up to 4 indexes for up to 6 mm D.O.C.
RQMT1204ENC6-MM
Allows up to 6 indexes for 2.6 mm or smaller D.O.C. and up to 3 indexes for up to 6 mm D.O.C.

Practical examples
Example #1
| Part: | Mold |
| Material: | S45C / C45 |
| Cutter: | TRRQ12M050B22.0R05 (DCX = 50 mm, CICT = 5) |
| Insert: | RQMT1204ENC8-MM |
| Grade: | AH3135 |
| Cutting conditions: | Vc = 125 (m/min) fz = 1.25 (mm/t) ap = 0.5 (mm) ae = 50 (mm) Application: Profiling Coolant: Air Machine: Vertical M/C, BT50 |
The competitor’s cutter resulted in edge chipping and could not complete the machining of one workpiece.
FixRMill demonstrated no edge chipping and completed one workpiece thanks to its tough AH3135 grade inserts.
Example #2
| Part: | Generator part |
| Material: | SUS304 / X5CrNi18-9 |
| Cutter: | TRRQ12M050B22.0R06 (DCX = 50 mm, CICT = 6) |
| Insert: | RQMT1204ENC8-MM |
| Grade: | AH3135 |
| Cutting conditions: | Vc = 75 (m/min) fz = 0.3 (mm/t) ap = 1 (mm) ae = 3 (mm) Application: Profiling Coolant: Air Machine: Vertical M/C, HSK100 |
Due to a long overhang setup of 4xD and insecure anti-rotation feature, the competitor’s cutter allowed the inserts to rotate during machining, yielding damage to the insert pockets and short cutter tool life.
FixRMill prevented insert rotation thanks to its anti-rotation system, providing the cutter with security and long tool life.
