MZG Screwed / Modular Tool Holder Systems
This cutting-edge tooling philosophy represents a paradigm shift in manufacturing efficiency, moving away from monolithic, single-purpose tools towards a highly adaptable, interchangeable platform. The system's architecture is elegantly simple yet profoundly effective: a high-precision threaded connection joins a reusable, robust tool holder shank with a wide variety of specialized, replaceable cutter heads. This modularity is the key to unlocking significant reductions in production costs, minimizing tool change downtime, and delivering exceptional performance across a vast spectrum of milling operations, from heavy roughing to high-precision finishing.
High-Precision Shoulder Milling & Superior Surface Finishes
R390, ASMM, RT, and TE90 heads deliver exceptional precision with tapered design for high rigidity. ASMM (Super Excellent Mini) achieves rotation and feed rates up to 3 times higher than general cutters while maintaining blade edge runout accuracy within incredible 5μm, critical for high-tolerance mold, die, and aerospace components.
Versatile Roughing & Profiling with Economic Efficiency
AHUM, TRSM, and EMRM series utilize strong positive angle blades (15°) and economical round inserts (RPMW, RDMT) for smooth cutting action with excellent chip evacuation. Tapered body design ensures high rigidity while multiple cutting edges provide significant cost-per-edge advantage for roughing, pocket milling, and complex copy milling.
Multi-Functional Drilling & Milling Performance Integration
TJU and ASJ cutter heads break conventional boundaries with hybrid design capability. TJU offers versatile drilling and milling with small cutting resistance, while ASJ specializes in deep roughing with seamless transition from drilling to milling in 'bottom-free' state, drastically reducing cycle times by eliminating tool changes.
Product Performance
The performance of our Screwed/Modular system is multifaceted, delivering specialized excellence through its diverse cutter head offerings while providing overarching system-level benefits.
High-Precision Shoulder Milling Performance: For applications demanding flawless 90° shoulders and superior surface finishes, our system excels. The performance of heads like the R390, ASMM, RT, and TE90 is defined by their precision. The R390 series, with its tapered design for high rigidity and compatibility with precision-ground inserts, is a master of finishing. The ASMM (Super Excellent Mini) takes this to another level, delivering powerful cutting with rotation and feed rates up to 3 times higher than general cutters, all while maintaining blade edge runout accuracy within an incredible 5μm.
Versatile and Economical Roughing & Profiling Performance: The system demonstrates exceptional strength in general-purpose and profile milling. The performance of the AHUM, TRSM, and EMRM series is rooted in their robust design and insert economy. Utilizing strong positive angle blades (e.g., 15° for EMRM/TRSM) and round inserts (RPMW, RDMT), these heads deliver a smooth cutting action with excellent chip evacuation, making them ideal for roughing, pocket milling, and complex copy milling.
Multi-Functional Drilling & Milling Performance: Our modular system breaks conventional boundaries by integrating multiple operations into a single tool. The performance of the TJU and ASJ cutter heads lies in their unique hybrid design. The TJU is a versatile workhorse, capable of both drilling and milling with small cutting resistance. The ASJ is a specialist for deep roughing, engineered to transition seamlessly from drilling to milling in a "bottom-free" state, drastically reducing cycle times by eliminating tool changes.

Modular Screwed Connection & Cutter Head Geometries
High-precision, fine-pitch thread provides secure, rigid, and highly concentric connection ensuring maximum torque transmission and minimal runout. System supports Right Angle Shoulder Milling Heads (M6NTE90, 3PTE90, R390, TE90), Corner Rounding Bull-Nose Heads (EMRM, TRSM), Drilling & Milling Heads (TJU, ASJ), and Face Milling Heads (4NKT) for comprehensive machining versatility.
Insert Systems & Secure Clamping Technology
Comprehensive range of industry-standard inserts including M6NGU, 3PKT, JDMT, R390, RT-series, AXMT, RPMW, RDMT, 4NKT, and CCMT/CPMT for optimization based on material, operation, and cost. Each cutter head employs robust screw-down clamping system (M2.5x6, M4x10 with T8/T15 wrenches) preventing movement under heavy cutting loads.
Tool Holder Design & Internal Cooling Systems
Reusable shanks manufactured from high-quality alloy steel for durability and rigidity, available in various lengths and shank diameters. Many tool holders feature internal cooling holes for high-pressure coolant delivery directly to cutting zone, with M6NTE90 and 3PTE90 exemplifying advanced cooling integration for enhanced performance and tool life.
