MZG Face Mill Tool Holder System
MZG present a comprehensive and detailed introduction to our range of Face Mill Tool Holders. These holders are not merely adapters; they are the critical foundation for all face milling operations. Engineered with extreme rigidity and precision, their sole purpose is to securely mount large-diameter face milling cutters and transmit the immense torque required for high-volume metal removal, all while maintaining the stability needed for exceptional surface finishes. The design is based on a robust, multi-point contact system that ensures the cutter is held immovably against the immense forces of the cut.
Exceptional Rigidity and Stability
Core performance characteristic achieved through large-diameter flange providing broad, stable contact face with back of milling cutter. Cutter precisely located by pilot bore and pulled tightly against face with central locking screw.
Secure Dual-Locking System
Robust dual-locking system handles high rotational torque. Central screw provides axial clamping force, while drive keys on pilot engage with slots in cutter. Two side locking screws firmly secure drive keys.
Guaranteed Precision and Surface Finish
Manufactured to exacting tolerances, including pilot diameter tolerance of h6 and taper tolerance of AT3 on dual-contact models. Ensures face mill runs true with insert plane perfectly perpendicular to spindle axis.
System Performance Analysis
The performance of a Face Mill Tool Holder is defined by its rigidity, the security of its clamping mechanism, and its ability to maintain precision under heavy loads. The core performance characteristic is unyielding rigidity achieved through large-diameter flange.
This provides broad, stable contact face with the back of the milling cutter. The cutter is precisely located by pilot bore and pulled tightly against this face with central locking screw. This rigid, face-to-face contact dampens vibration, prevents chatter.
To handle high rotational torque, our face mill holders employ robust dual-locking system. In addition to central screw providing axial clamping force, holders feature drive keys on pilot that engage with slots in cutter. Two side locking screws firmly secure these drive keys.
The precision of the holder is paramount for achieving perfectly flat, smooth milled surface. Our holders are manufactured to exacting tolerances, including pilot diameter tolerance of h6 and taper tolerance of AT3 on dual-contact models.

Technical Parameters
Cutter Mounting System & Precision Tolerances
FMA Type: Features imperial-standard pilot diameters for cutters with inch-based mounting bores (e.g., 25.4mm for 1", 31.75mm for 1.25", 38.10mm for 1.5"). FMB Type: Features metric-standard pilot diameters for cutters with metric mounting bores (e.g., 22mm, 27mm, 32mm, 40mm). Pilot Diameter (D1): h6. 7/24 Taper: AT3 (for DAT models). Inner Hole: H5 (for DAT models).
Dynamic Balance & Locking Mechanism
Standard G6.3 at 8,000 RPM. HSK models standard G6.3 at 3,000 RPM. Higher grades (e.g., G2.5) and speeds available upon request. Central locking screw (for axial pull) combined with two side locking screws on pilot drive keys (for rotational lock).
Shank Interface Types & Critical Ordering Information
Available in complete range: BT (versatile and robust workhorse for general CNC machining), HSK (for modern high-speed machining centers), DAT (Dual Contact for high-precision machines with dual-contact spindles), NT (for older, heavy-duty conventional milling machines). When ordering NT-style holders, essential to confirm required pull rod (drawbar) thread specification (metric or imperial) to ensure compatibility.
Application Scenarios & Applicable Machining
Application Scenarios
- Primary Application: Their sole purpose is face milling. This includes Heavy Roughing (rapidly removing large volumes of material from face of workpiece), Fine Finishing (creating smooth, flat, and precise surfaces on large areas), and Datum Creation (machining primary flat reference surfaces on part)
- Industries: Essential in any industry that machines large metal components, including mold & die, aerospace (machining structural components), automotive (engine blocks, transmission cases), and general heavy engineering
- Machine Compatibility: The specific holder (BT, HSK, DAT, NT) is chosen to match the spindle interface of the CNC or manual milling machine being used
Main Functions
- Provide Ultra-Rigid Mount for Face Mills: Core function is to create immovable connection between machine spindle and face milling cutter, capable of withstanding extreme cutting forces without vibration or deflection
- Ensure Positive Rotational Drive: Functions to transmit full torque of machine spindle to cutter without any slippage, primarily through use of robust drive keys secured by side-locking screws
- Guarantee Perpendicular Alignment: Functions to hold face mill in precise perpendicular alignment with spindle's axis of rotation, which is absolute requirement for producing flat machined surface
- Enable High-Performance Machining: Functions to support high-speed and high-feed milling operations by incorporating features like dynamic balancing and through-spindle coolant delivery, maximizing productivity and part quality
