Roto tool...and a side cutting drill bit...

Post by zap101 » Sun Nov 04, 2007 4:48 pm

If cost is a factor...try using a high RPM roto-tool with a side cutting drill bit...Both are available at a larger Hardware store...Ace or home depot etc...Be sure you get the side cutting bit for al. and not drywall...The last time I bought the bits they were 3 for 10.00...
