Product Information

Damon's answer from 2016 correctly points out the easily overlooked dangers of using a router in this way. If you are lucky it "works fine", but now the collet no longer grips the original bits firmly and safely, so you have the risk of a bit flying away in a random direction every time you use the tool "properly" with the correct bits. There is a bit of tolerance, so you can certainly fasten the screw harshly enough to do those extra 0. When it comes to using a routing tool to fashion shapes within a multitude of materials, not a lot can be achieved without router bits. As previously mentioned, up cut router bits are often applied in the removal of chips from the hole being cut.

The spinning action of router cutters allows for the design and creation of shapes within a variety of materials.Router bits are essential for fashioning shapes into a selection of materials through the use of a routing tool. The bit isn't going to have a sufficiently firm, safe grip, and you cannot be sure whether you have structurally damaged the collet by bending the little clamps too harshly. Simply put router collets are designed on the same principle as a drill chuck that accepts different size bits. If you are unlucky, the whole thing blows to smithereens at 25k RPM with shrapnel flying all over the place and the bit come off flying in a random direction. However, using an imperial bit in the corresponding (well, almost corresponding) metric collet is dangerous both during the operation and when using the collet with your 6mm bits as intended afterwards.

I'm not an expert on the different tool holding mechanisms (my equipment either has a chuck or an ER-32 collet), but the ER type collet is the type of geometry, with the number following it is the overall size.
