Not Worth the Investment

based on my experience, this product failed to MEET my expectations. While it was marketed as a high-quality workholding tool it quickly became apparent that it lacked the necessary durability and precision to handle even moderate use. The only positive aspect was its ease of use, but that was overshadowed by its overall poor performance. Save your money and invest in a more reliable option..

Pros
  • Easy to use
Cons
  • Poor performance and durability

Great price and within tolerance

I would like to apologize to the seller and readers as my previous review was based on measurements with a defective micrometer. After discovering the problem, I repeated the measurements on both collets with another, new one, and the performance is well within the specified tolerances. Great collets, good accuracy, great price.

Pros
  • Durable finish
Cons
  • Damaged
