The polygon taper ensures automatic radial centering and even pressure around the coupling, according to Sandvik Coromant, enabling repeatability within 2μm.
“I found the three-sided polygon provided superior stability.” “Why does a modular system have to be circular?” Andersson asked. The Coromant Capto’s three-corner polygon shape distinguishes it from other toolholders. We drove this certification to make sure no one could change the design, and that’s what ISO certification achieves.” “We wanted to ensure that if anyone makes it, and anyone is more than welcome to make it, all the tolerances are exactly the same as the original. “When the patent ran out, we didn’t want people to make a lower-quality version so that it started to create problems for those who had Coromant Capto,” said Chris Mills, national portfolio manager for Sandvik Coromant, Fair Lawn, N.J. Sandvik Coromant’s Coromant Capto machine adapted clamping units (MACU) for lathes are suitable for turning and milling applications. ISO certification means no manufacturer can sell a Coromant Capto holder that doesn’t conform to the standard’s specifications. Since then, Coromant Capto has made industry inroads via sales by Sandvik Coromant and its various licensees and was adopted in 2008 as an ISO standard (26623) for toolholding systems when the company’s patent expired and the need to license it ceased.

Sandvik Coromant completed the first prototype in 1989 and unveiled the full version at IMTS 1990 in Chicago. Ken Andersson, who has since retired from the toolmaker and now builds boats, invented Coromant Capto. For the Coromant Capto toolholding system developed by Sandvik Coromant Co., modularity, universality and repeatability define it. Those are definitions of the Latin word capto. A look at the Coromant Capto modular toolholding system.
