The FletaSize: 4 mm x 6 mm x 11 mm x 55 mm / 6 mm x 6 mm x 13 mm x 57 mm / 8 mm x 8 mm x 19 mm x 63 mm / 10 mm x 10 mm x 22 mm x 72 mm / 12 mm x 12 mm x 26 mm x 83 mm. Strong and durable: This milling cutter is made of HSS and has high bending strength and abrasion resistance. It is only suitable for milling high hardness steels and high cutting speeds. High processing efficiency: The cutter edge is hard and sharp with TiAIN coating, heat treatment materials are processed at a temperature below 32 C at high speed, which reduces replacement times and improves production efficiency. Cutting Edge: The bottom of the milling cutter is U-shaped, the large front angle effectively reduces the cutting resistance, is sharp, durable, convenient for chip removal, further improving processing efficiency. Usage: This milling cutter is suitable for side milling, face milling, finishing, etc. For carbon steel, alloy steels, steel, tool steel, cast iron, titanium, aluminum, etc. Features: Milling cutters generally mounted on milling machines. Suitable for CNC computer processing centers, high-speed carved machines. Can mill copper, aluminum, tool steel, cast iron, etc. High hardness, abrasion resistance, high-speed cutting for high-hardness steels. Can be used directly or finely processed. Reduce the number of tool replacements, improve the machine movement rhythm, and save time in mold manufacturing. Specifications: Material: HSS. Model: 4 / 6 / 8 /10 mm for choice.
