Bosch 1617evs router. the 1/4 in chuck collet has a diameter of .550 in. the opening in the shaft is .500. how to fit?

I suspect you are seeing the part that makes the collet work. The tapered part of the collet fits a taper in the router spindle. As you tighten it, the taper works like a wedge to compress the collet. That's what the slots are for. Please forgive me if you already knew all this and you actually have a defective collet!

Will this collet fit my model 1614 Bosh plunge router

Thank you for your question. The 2610906283 Collet only works with 1613 series, 1617 series, 1618 and 1619 series routers. For further assistance, contact us at 1-877-BOSCH99 (1-877-267-2499) from Mon-Fri 7A-7P CST.
