I would like some advice on the type of steel(s) to use for some
collets I need to make.
1st is an 8mm collet for an old Hitachi router. Hitachi want =A347.46 +
VAT which is why I'm going to make it! This is a split collet which
screws into a 'chuck' and tightens on the shank of the cutter.
2nd are a set of metric collets for my Modeloy milling chuck. For
those who are not familiar with the Modeloy it is a smaller and
simplified version of the Clarkson chuck.
My stock of steel is of unknown provenance, some of which is free
cutting. Would this be suitable for both types of collet or do I need
a particular grade of steel for either job?
Thanks in advance.
