M-Type Tool Holder | Designed for High-Efficiency, Stable, and Precision Machining
Product Overview
The M-type tool holder is a high-performance CNC tool holder, precision-manufactured from high-quality alloy steel. Through heat treatment and surface hardening, it possesses excellent rigidity, wear resistance, and vibration resistance. Its unique tool holder locking and positioning design is specifically optimized for **D-type (rhombic) inserts**, and is widely used in profiling, contour milling, and finishing and semi-finishing of bevels and cavities. It is an ideal choice for efficient machining of complex curved surfaces.
Core Advantages
1. Excellent Rigid Structure
The M-type tool holder body features a reinforced rib design and optimized cross-section, significantly improving overall rigidity and effectively suppressing cutting vibrations, ensuring stability under heavy load or intermittent cutting conditions.
2. High-Precision Positioning and Locking
The precision-ground positioning groove and locking mechanism ensure high repeatability of D-type insert installation, eliminating the need for re-tooling after insert changes, greatly improving machining efficiency and dimensional consistency.
3. Optimized Chip Evacuation and Cooling
The streamlined design of the tool holder facilitates smooth chip evacuation, preventing chip entanglement and accumulation. It is compatible with various coolant delivery solutions (such as internal cooling options), effectively reducing cutting temperature and extending tool life.
4. Wide Applicability
Compatible with mainstream D-type (rhombic) negative rake angle inserts on the market, such as DNMG and DCMT series. By changing inserts with different angles, it can flexibly handle a variety of machining geometries.
Technical Parameters
Tool Holder Model Example: MTGNR/L 2020M-16 (Specific model depends on specifications)
