As title says. Want to try my hand at some head porting. I have a few but need some different ones to get in some of the tight spots. Ive bought snap on before, crazy price. I bought a couple from Fastenal yesterday, not as lofty as snap on but still nuts. 3 cost me over $60 I am wanting some of the long shank ones. A point, a tree style, a ball Burr, and a conventional straight one possibly with capability to end-mill/end grind Suggestions?
