I have really never had to cope much stainless tubing. Trying to use the normal tubing notcher with a hole saw doesnt work well. The stainless is .050 wall and the morse hole saw grabs and binds more than cuts. Is there a hole saw with higher TPI or something you guys would recommend?ThanksBrandonLots of toys.
Reply:Yes, there are fine tooth hole saws available. Look here: http://www.medfordtools.com/metalworking/holesaws.html or http://www.vansantent.com/hole_saw_cutters_JMR.htmThe best tool for notching thin wall tube is a belt sander type tube notching machine. Like this: http://vansantent.com/coping_machine.htm. You should check if any of your local fab shops have one.Another option is using a miter saw. With such thin tubing it is posible to make two miter cuts that will result in a near perfect cope.Ian TannerKawasaki KX450 and many other fine tools
Reply:Some hole saws don't have teeth, instead they have tungsten carbide grit brazed/bonded to the cutting edge, I have used these before to cut holes into enamelled cast-iron bath tub to fit Jacuzzi nozzles. Worked pretty good.Lincoln SP-170 MigHypertherm powermax 45Lorch T220 AC/DC TigButters FM 215 synergic MigKemppi 180 adaptive mig RULES ARE FOR THE OBEDIENCE OF FOOLS AND THE GUIDANCE OF WISE MEN.
Reply:Can't you just use a 4 1/2" grinder with a flap disc? Takes a bit of practice, but you can get good results.Last edited by Baila La Pinza; 12-06-2010 at 01:37 PM.
