This 7 piece collet set is simply amazing! When i tried this product, I WAS pleasantly surprised by how well it fit my workholding needs and how durable it was. The industrial and scientific build of this product ensures that it delivers optimum performance every time... The only con I could find is that it may not fit all types of machinery. Overall, I highly recommend this product to anyone in need of robust and efficient workholding tools..
Pros
High-quality collets made from durable materials
Cons
May require additional accessories for use with certain machines
It's nice when you can get good collets at no extra charge. For many years I only used old 3/8" and 1/2" collets on my old #7 B&S M head (which was sold to me as a morse taper spindle - glad I checked that out).
