LR high-precision end mill chuck

Product Description

• Using an ER collet to mount an integer shank tool reduces the amount of extension and significantly increases the clamping force.
  (Expansion/retraction: ER 1MM / LR 0.25MM)
• The fine-tooth, long-thread design prevents it from loosening even after long-term use.
• The nut features a round, low-wind-resistance design, and the hook-shaped wrench is simple and convenient to use.
  (Bearing-type nuts and wrenches are also available as optional accessories)
• Ligang manufactures a variety of ER collets in various specifications for your selection.
