External turning tool holder TurningA

for internal turninghigh-rigidityhigh-accuracy

Overview
Highly rigid "Double‑Clamp" system provides remarkable stability and high accuracy.

Applications

• Internal turning
• External turning

Features

• Simple and strong double‑clamp system: Provides strong clamping force with one screw. One screw and one action delivers double clamping force by simultaneously pushing down and pulling, providing high stability for the cutting edge.
• Higher indexing accuracy
• Unique clamp improves rigidity: Larger holding area enhances clamping force drastically. Higher rigidity provides excellent stability and reduces vibration.

Inserts

• Inserts for External Turning
• Inserts for Internal Turning
• ISO‑EcoTurn Inserts: Economical small size insert

Main Grades

• T9215: P10 – P20; Well‑balanced between wear and chipping resistance; First choice for steel; High versatility for a wide range of applications
• T6130: P15 – P30 / M15 – M30; High wear resistance in cutting at medium to high speed; First choice for stainless steel
• T515: K10 – K20; Stable machining in a wide range of applications from continuous to interrupted cutting
