i said boring head as an example of the type of upgrade where i could put more money if i would go with a SX3 instead of a tormach but you are right that reamer would be better at this job or actualy honing in a way to finish in thight tolerance

that would actualy be what i would want people point view on, i do understand that these machine tend to vary more from one another but in a overall point of view do you think i might be able to get pretty close to what i am looking for, i definitly should have precised more the size of the hole, i am talking of hole where the size would be between 1/8 and 5/8 and range from 1/4 to 3/4 inch deep, but i do understand that those machine are as tight as big machine, i am mostly looking if those machine have so far respected there advertised accuracy or if they have so far tend to be uterly off precision wise to what there advertised.
