<VV> Re: [fastvair] cleaning up cly heads

[JVHRoberts at aol.com]

Well, get drill bits which have flute only on the last inch or so. Tool  
suppliers can get these. I made a tool for my air chisel by brazing a piece of  
cut off tool stock into a slot machined into the end of one of the chisels and  
buzzed a lot of stuff out that way. 
 
IF you're using the drills, make sure they are sharp, you take it easy, and  
run them VERY fast. Also, change the bit often, there's casting sand still  
trapped in the surface, and it does dull bits.

Howdy  Folks,

I have been using 1/8" drill bits to clean up the casting and  flashing 
between the cooling fins. I broke quite a few bits but the heads are  real nice 
now. Does anyone have a better way of doing  this?

Bob
