Quick Answer

The Collet Tool Changing Fixture lets you tighten or loosen Tormach TTS ER-16 and ER-20 tool holders while they're held securely in a vise, making tool changes faster and more consistent.

Why Use a Dedicated Fixture?

Holding a TTS tool holder by hand while tightening a collet can be awkward and may lead to inconsistent grip. The fixture gives you a stable platform—simply clamp it in a vise—so you can apply proper torque with a separate wrench without the holder spinning.

Limitations to Know

The fixture only works with Tormach TTS tool holders that use ER-16 or ER-20 collets. It does not support other shank sizes or non-TTS holders. Also, you still need a separate wrench for the collet nut—the fixture itself does not include one.

How to Set Up and Use the Fixture

  1. 1. Mount the Fixture in a Vise: Place the fixture in a vise with the desired wrench end (ER-16 or ER-20) extending out. Tighten the vise enough to hold the fixture steady but not so much that it deforms the slot. Make sure the correct wrench end is exposed for your tool holder's collet size.
  2. 2. Insert the TTS Tool Holder: Slide the TTS tool holder into the slot on the fixture until it seats fully. The holder should be vertical and stable. If the holder rocks, the vise may not be tight enough, or the slot might have debris.
  3. 3. Loosen or Tighten the Collet Nut: Use a separate wrench on the collet nut to loosen or tighten the tool in the holder. The fixture prevents the holder from rotating. Apply steady pressure—over-tightening can damage the collet or holder.
  4. 4. Remove the Tool Holder: Once the collet nut is adjusted, slide the tool holder out of the fixture. Your tool is now ready for use in the mill spindle. Always double-check that the tool is secure before running the spindle.
