Modular end milling

The Duo-Lock is a coupling for solid carbide end milling applications. The replaceable head design combines a high accuracy in runout and length repeatability with maximum stability, making it a precise and durable interface. With a Duo-Lock wrench the tool change is simplified and can be done in a few seconds.

The Duo-Lock system consists of:

HARVI I TE & HARVI I TE Ball Nose

• Twisted cutting edge increases corner stability, enables soft cutting action even at highest ramping angles
• Asymmetric divided flutes and variable helix enable vibration dampening, unmatched feed rates
• Relief with AVF-Technology, a precision faceted eccentric relief reduces vibrations and friction
• Chip gashes within the flutes reduce cutting forces, support efficient chip evacuation

Double cone

• Eliminates presetting processes by providing an axial 0.0004" (10μm) repeatability
• Length repeatability from insert tip-to-tip within 0.0020" (50μm)
• Intelligent thread ensures stress level remains below critical values, allowing >25% higher transmittable torque
• Third contact surface delivers high stiffness and accuracy below 0.0002" (5μm) runout

Solid ER collets for Duo-Lock

• Adapts Duo-Lock modular end mills to CNC lathes
• Turns CNC lathe machines into multitasking machines by providing access of any Duo-Lock modular end mills to ER driven units
• Maximize machine flexibility through a range of Duo-Lock modular end mills – from high-performance versatile tools to roughers and finishers, chamfering, and corner rounding tools
• Short projection from face of collet nut provides rigid toolholding, requires small machine envelope
• Compatible with all standard ER collet chucks and ER driven units
