Tier Tool
1 / 5
CNC machine industrial quality high precision surface.
The milling cutter is made of micro-tungsten carbide, which is very tough, wear-resistant and high-cutting.
Milling cutter of different sizes to suit different usage scenarios. Smaller milling cutter are suitable for precise and delicate work such as model making or handling electronic components. Larger milling cutter are suitable for larger work areas and thicker materials, such as cutting and carving wood or metal.
The nano blue coating has high hardness and heat resistance, which keeps the tip of the tool critically sharp and lubricated. This extends life and produces the highest quality cuts.
