In high-precision electrode manufacturing and mold making, tool reach and surface quality are critical. The SAMHO DLC-Coated Long Neck Series is engineered to provide stable, mirror-like finishes in deep-cavity applications where standard tools fail due to vibration or material smearing.
Advanced Technical Features
- DLC Coating: The Anti-Stick Solution for Copper & Aluminum
The Diamond-Like Carbon (DLC) coating acts as a solid lubricant with exceptional surface hardness and anti-adhesion properties:- Prevents Chip Welding: Eliminates built-up edge (BUE) even during high-speed dry cutting
- Enhances Tool Life: Reduces friction-induced heat, maintaining edge sharpness for longer production runs
- Long Neck Design for Interference-Free Deep Milling
Extended neck geometry provides superior clearance for deep cavity and narrow features:- Reach Deep Contours: Ideal for complex 3D mold cores and undercuts
- Maintain Rigidity: Optimized neck-to-diameter ratios ensure stable cutting with minimal deflection
- 2-Flute Ball Nose Profile for Smooth 3D Surfaces
Precision-ground spherical tip ensures seamless 3-axis contouring:- Seamless Transitions: Smooth finishing of curved surfaces and freeform geometries
- Reduced Polishing: High-quality finish minimizes secondary manual polishing
- Mirror-Polished Flutes for Rapid Chip Evacuation
Mirror-polished flute surfaces provide high-lubricity design:- Excellent Chip Flow: Prevents clogging in deep slots and narrow pockets
- Dimensional Accuracy: Minimizes cutting forces that cause errors in ductile materials
