Product Name : ER Collet
  • Design: 8 slots in front and back, with good flexibility and convenient for clamping tools.
  • Steel: SUJ2 (High-carbon bearing steel: After heat treatment, it has high hardness and toughness, better grinding quality, good flexibility and longer use life.)
  • HRC: 46°
  • Surface roughness: within Rz2.5
  • Chucking range: ER8 = 0.5mm
  • ER11, 16, 20, 25, 32, 40 = 1mm. But if the internal hole is less than 2.5mm, the chucking range will be 0.5mm.
  • The internal hole is manufactured by precise honing.
  • The concentricity is inspected according to DIN-standard. There are three classes of precision: general class 0.02mm, A class 0.01mm.
  • UP class is recommended to be used with HSP clamping nut. It will have better processing stability.
  • It is used for drills, taps, mills, and reamers, etc.
  • It has flexibility and can be applied widely and variably.
  • Please inform the required precision when ordering.
  • Yearly sales quantity about 1,000,000 piece
