Product name :ER40 Collet Metric System. Material: High precision 65Mn45 steel.Tool body process: integral forging surface material: sandblasting treatment. Application: Suitable for milling, drilling, tapping engraving, CNC and other clamping tools. Processing note: The effect of adding coolant is better when processing, do not rough processing. Features: Strong Elasticity, High Hardness. High concentricity/clamping force, wide range.
Spring steel material: high hardness/wear resistance and durability. Heat treatment method of martensitic structure: effectively avoid cracking and deformation. Strong clamping force, large elasticity. Reduce interference, reduce vibration, high-speed processing is more stable. Suitable for milling, drilling, tapping engraving, CNC.Each collet has a box.
