Features: Integrated forgings of highly Manganeses steel: Main body of the saw Cutter adopt highly Manganeses steel materials, which have undergone multiple highly-frequency forgings and pressings alloys, with highly hardnesses and strong toughnesses. Saw Cutter thickness of 1mm: highly substrates flatness/smooth operatings/highly efficiency. The sawtooths adopts a new alloys particle brazing process to improve cutting sharpnesses. Smooth cutting without bursting edges: smooth chip removal/no heating during cutting/less to burning and edges collapse during highly-speed operatings. Suitable for wood board, unpainted board, composites, and other types of wood. It can also be used to cut PVC engineering pipe, plastics, rubber, aluminum alloys, steel, etc. Specifications: Material:Manganeses Steel Diameter:110mm/4.33'' Hole Diameter:20mm/0.79'' Thickness:1mm Package Includes: 1Piece Circular Saw Cutter note: Please allow 1mm errors due to manual measurement.
