MZG OZ Tool Holder System
MZG provide a comprehensive and detailed introduction to the OZ Tool Holder system. Explicitly designated as a heavy-duty cutting tool holder, the OZ system is the quintessential choice for machining applications that demand immense clamping force and unwavering stability. It is a robust, collet-based system engineered to withstand the significant stresses of aggressive roughing and high-torque milling operations.
Exceptional Clamping Force
Core performance is ability to generate tremendous clamping force. OZ collet combined with heavy-duty clamping nut provides powerful, full-contact grip essential for preventing tool slippage during heavy-duty cutting.
Outstanding Rigidity and Vibration Damping
Immense clamping force creates incredibly rigid assembly between tool, collet, and holder. High rigidity effectively resists tool deflection and dampens vibrations, enabling aggressive depths of cut and higher feed rates.
Robust and Durable Construction
Built to endure harsh conditions of heavy machining. Solid construction ensures absorption of high torque and radial loads associated with roughing without compromising integrity, translating to long service life.
System Performance Analysis
The performance of an OZ Tool Holder is defined by its raw power, exceptional rigidity, and durable construction, making it a reliable workhorse in demanding environments. The core of the OZ system's performance is its ability to generate tremendous clamping force.
The OZ collet, combined with a heavy-duty clamping nut, provides a powerful, full-contact grip on the tool shank. This secure lock is essential for preventing tool slippage or pull-out during heavy-duty cutting, deep slotting, and operations using large-diameter cutters, where cutting forces are at their peak.
The immense clamping force creates an incredibly rigid assembly between the tool, collet, and holder. This high level of rigidity effectively resists tool deflection and dampens vibrations at the source, critical for enabling aggressive depths of cut and higher feed rates.
OZ tool holders are built to endure the harsh conditions of heavy machining. Their solid construction ensures they can absorb the high torque and radial loads associated with roughing without compromising their integrity, providing broad machine compatibility across extensive range of machine taper interfaces.

Critical Ordering Information
When ordering holders that require pull stud (e.g., NT, MT), essential to confirm required pull rod thread specification (metric or imperial) to ensure compatibility with machine's drawbar. System bridges gap between new and legacy equipment.
Application Scenarios & Applicable Machining
Application Scenarios
- Heavy-Duty Roughing: Primary application excelling at aggressively milling large volumes of material from steel, cast iron, and other tough alloys with maximum efficiency
- High-Torque Milling: Ideal for using large-diameter end mills, shell mills, and face mills where significant rotational force and slip-proof grip are required
- Conventional and Manual Milling: Availability of R8, Morse Taper (MT), and NT shanks makes OZ system perfect performance upgrade for Bridgeport-style mills and conventional machines
- Drilling and Boring: Strong clamping force makes it suitable for holding large drills and boring bars securely, preventing rotation within collet during high-torque hole-making operations
