Precision Collet Chuck - DIN 6499/ISO 15488
  • For high-precise clamping of tools with cylindrical shank in ER collets.
  • ER collets according to DIN 6499/ISO 15844 standards.
  • This particular collet chuck is a unique high precision and performance chuck that is used with a special clamping nut.
  • A collet chuck for the highest machining capacity in high-speed manufacturing. 
  • Its flawless design externally and internally combines high rigidity with vibration dampening features, giving more protection to machines, spindles and tools. 
  • High-gripping torque combined with excellent runout accuracy for high-precision and high-performance machining.
  • Improved shank design and full gripping length of the collet eliminate collet collapse and distortion, which has a negative influence on the concentricity.
  • Runout of outer taper to inner taper within 0.003 mm.

    Remark: Only the nominal size can be clamped, since only then the best concentricity and clamping force is achieved!
