Release time:

2025-11-08

  1. Check compatibility
  • Chuck and spindle: make sure the adapter fits both (bolt pattern, thread type, and nose size).
  • Chuck size: ensure the adapter doesn’t exceed the chuck’s max grip or clash with jaws.

 

  1. Pick the adapter type
  • Backplate: sits between spindle and chuck to adapt bolt pattern or diameter.
  • Faceplate adapter: lets a different faceplate fit your spindle or chuck.
  • Spacer/Null adapter: fixes alignment without changing the chuck.
  • Thread adapter: changes imperial/metric threads.

 

  1. Important dimensions
  • Bolt pattern: count bolts and measure the bolt circle diameter.
  • Outer diameter and height: must clear everything and stay true.
  • Thickness: keeps the chuck aligned with the spindle axis.
