Features
• Excellent thermal characteristics, cooling the drill bit and reducing resin build up.
• Manufactured from hard drawn aluminum, maximizing machinability whilst maintaining high thermal conductivity and burr reduction.
• Excellent flatness and controlled surface roughness combines to provide reliable drill centring, reduced wander and drill breakages.
• Protects the underlying substrate from pressure foot marks and scratches.
• Fully recyclable.
Applications
1. Aluminium Drill Entry sheet can protect the circuit board against scrapes and pressing marks.
2. Aluminium sheet enhances the nicety amount of the drilling placement. It creates the drilling have assistance to ensure that the drill functions without deflection.
3. It significantly lengthens the life span of the drill little bit. Its particular alloy composition will keep the cleanness and the cooling of the drill little bit. Whats more, it really is an excellent conductor of warmth so it helps prevent overheating of the drill little bit and it can prevent the oxidation of the top.
