  • The tool should not be inserted into the collet less than 2/3 of the caliber of the collet.

  • Each product has its own special storage box, which is very convenient for you to store and carry.

  • This is OK, ER20 spring collet is widely used in boring, milling, drilling, tapping, grinding engraving and other processing, and with CNC tool handle matching use.

  • The spring collet must tighten the nut with the hook wrench to clamp the tool, so as to avoid the tool flying out during high-speed rotation and causing accidents.

  • This product is mainly used to tighten drilling tool or milling tool, can also be used to fix the need to transform the processing parts, the main function is to lock the tool and the spindle connection.

The 1/8" , 3/16" , 1/4" (I ordered duplicates as well unfortunately for my TTS holders) sizes have over .003 of run out making them useless for the work I do. I did not return them since I could use the other sizes, those have about .0015 of run out. It is disappointing but I expected it at this price.

I use these mostly for drills, the inner surfaces are a little rough to get a good perpendicular grip on tools so I don’t use them often for end mills unless I’ve lapped the insides of them

I just bought a new spindle with an ER20 collet chuck... of course they only come with one size. I've seen people use an adapter for smaller 1/8-inch or 3mm bits... just get this set and you are ready for 1/8 through 1/2 inch. (3 to 12 mm). Do it right... have fun!

I have only used about half of them so far, but those that I have used appear to have a T.I.R. less than 1 micron! Great Value!
