Product Overview
The DT-MWLNR/L Internal Turning Tool Holder is a high-precision solution for CNC machining of internal diameters, grooves, and chamfers. Engineered with a 95° cutting edge angle and reinforced dual-support structure, this tool holder delivers exceptional rigidity and vibration damping during deep internal turning operations. Unlike standard internal tools, the DT-MWLNR series features an optimized insert pocket design that ensures full contact with WN*0804 inserts, minimizing deflection and enhancing dimensional accuracy in tight-tolerance applications.
Technical Key Features
- High-Rigidity Alloy Steel Body: Forged from 42CrMo alloy steel and heat-treated to HRC 48–50, providing superior strength and fatigue resistance under continuous loading.
- Precision Insert Pocket Design: The 95° angled pocket ensures full contact with WN*0804 inserts, reducing chatter and extending tool life.
- Dual-Support Clamping System: Reinforced clamp plate and center pin configuration distribute clamping force evenly, preventing insert rotation or misalignment.
- Optimized Chip Flow Path: The angled head design promotes efficient chip evacuation, minimizing built-up edge and thermal stress on the cutting edge.
- Anti-Corrosion Surface Finish: Nickel-plated or black oxide coating resists wear and corrosion in coolant-rich environments, extending service life.
Material Application Range
This tool holder excels across a broad range of materials:
- P (Steel): Carbon steel, alloy steel – ideal for interrupted cuts and high-feed internal turning.
- M (Stainless Steel): 304, 316 grades – enhanced heat dissipation prevents galling and improves surface finish.
- K (Cast Iron): Grey and ductile iron – excellent wear resistance due to high hardness and durability.
Why Choose DT-MWLNR/L for Your Workshop?
In modern CNC manufacturing, tool reliability directly impacts productivity. The DT-MWLNR/L enables rapid insert changes without removing the holder from the turret, preserving machine calibration and reducing setup time. Its compatibility with standard ISO WN-type inserts ensures cost-effective operation while maintaining high-performance standards. Designed for both general internal turning and precision finishing, it’s an essential addition to any high-volume machining facility.
