## Customer Reviews

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    the holders are great but the R8 collet is junk unusable.
  

*by J***R on Reviewed in the United States on May 10, 2022*

the holders are great the R8 collet does not go all the way into the spindle. however, the R8 collet does have the inner shoulder machined down, but the taper is too wide, or too long. I think it's too wide and closes before it can fully be pulled into the spindle.

    Trash components
  

*by T***R on Reviewed in the United States on June 2, 2024*

The r8 collet threading is incorrect, I tried to run a tap thru it, but the draw bar stripped out right away. The collet is also too long. So the TTS holders contact the collet not the spindle nose.Stay clear of this product.The holders seem okay, no taper on them so very hard to install.Save your time, buy from a real supplier.

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    It ok for the price
  

*by D***W on Reviewed in the United States on July 13, 2024*

These are good for how cheap they are.  One thing to note is that the 3/4 r8 collet is not cut flat like shown in the picture.  It is a standard 3/4 r8 collet.
