Just wondered artin what kit is it that your talking about from iscar? We just got a new boring head from valinite last week,the price went from $750.00 in 2005 to $1100.00 now ,and that was just the head!

I'll check on the exact p/n when i get to the shop tomorrow. But it includes the boring head, the boring bars, some inserts and adapters. It will do holes from .24" to 1.13", so you need a few different bars. I was a bit shocked at the price but managed to get the CAT40 adaptor thrown in the deal .
Also i just placed my order for the carbide balls to do some ball sizing. Any suggestions on how to push the ball through the hole? I was thinking drill press, but i'm not sure how much force i'm going to need to push a 1/2" ball through a .499" hole

artin,

your tolerance can be achieved with the iscar kit no problem if you ar erunning it in a quality machine. I was running that kit in Matsuura's and got repeatability of 2-3µm in 6061. If you are using it for a repeat job and will never change the size, don't bother with the kit, and just buy what you need and save your company some money! I have the same D'andrea kit that cuts from .236"-3.3" and I wouldn't trade it for the world!!!!

Dicker with your supplier and tell em you can get it for sa $1500 from someone else on line and see what they say. Iscar is willing to deal!
