You THINK it works,,,try this one and post back. > http://ccspecialtytool.com/catalog
Fact is ,you are using the WRONG tool for the job and you CANT get it how you really need it for max output with what you are using.
Yes you can "port" it some ,,and get some improvements,but especially when you are wanting "wide" power as you call it,thats when you really have to get in the transfers and massage. A dremel WILL NOT allow you to get in there properly.
Even WITH the proper hand pieces and after finding the perfect burrs that lcut the shape you need and reach just how you want,,,it takes a TON of time...using a 90* dremel attachment,,,,have fun.
