Jacobs taper or Morse taper for a drill chuck?
| Taper | Where it is | Typical sizes |
|---|---|---|
| Morse taper | Machine spindle to arbor | MT1, MT2, MT3 |
| Jacobs taper | Arbor to chuck body | JT0, JT6, JT33, JT3 |
| R8 | Mill spindle to collet or chuck | R8 arbor |
How to order correctly: read the stamp on the existing arbor, for example "MT2 / JT33". That single line is the whole spec. Guessing from the drill size does not work.
Why tapers slip: oil or dirt on the taper, or a burr from a previous spin. Clean both faces with solvent, seat firmly, and never grease a Morse taper — it is held by friction, not by lubricant.
