Trier posted a few pics of some Dremmel tools he's recently acquired. It made me wonder what tips/attachments people use most commonly.
For drilling out / hollowing helmets and heads what is preferred, a drill bit type attachmenet (like Trier's photo) or an Aluminum Oxide grinding stone (sort of triangular shaped)?
I've used the AlumOxid grinder in the past with moderate sucess, but the wedge shaped tips sometimes causes problems.
Any other tips, tools, or dremmel tricks??
