LONG TOOL LIFE MIRACLE COATED VP10MF

Longer tool life can be achieved by a combination of a very reliable coating and a carbide substrate, the best combination for threading.
LONG TOOL LIFE MIRACLE COATED VP10MF VP10MF displays high welding resistance, therefore it can be used for machining a wide range of workpiece materials such as mild steels, carbon steels, alloy steels, stainless steels and cast iron.

HOLDER

Special surface treatment has improved durability of the holder body.
