I have a machine that takes DA100 collets. I have a good selection of imperial (standard) collets by 64th, but I do not have any metric ones. I was wondering how big is the range of each collet and whether I could accommodate metric bits in my standard sized ones, without creating unnecessary hazards.
Here are some sample sizes:
6mm bit is 6mm exactly. will it fit the 15/64" collet which is 5.953mm or will it fit 1/4" collet which is 6.350mm
8mm bit is 8mm exactly will it fit in 5/16" collet which is 7.937mm or will it fit the 21/64" collet which is 8.334mm
10mm bit is 10mm exaclty. will it fit the 25/64" collet which is 9.921mm or the 13/32" collet which is 10.318mm
My big question is (for example, using the 8mm size) whether there will be enough grip with the 21/64" collet or if I should try to use it only in the 5/16" collet?
Which is safer?
Push comes to shove, I will buy metric collets, but I would like to avoid that if the nearest fractional collet is adequate and safe.
