Hey Paul and All,

>BTW can any engineer tell me if it is worth getting tungsten nitride tipped 
>drills for drilling steel panels? Do they last significantly longer? 

Titanium Nitrile coating do you mean?

Yes, they  lasy much longer, drill easier and cut cleaner. The S. Cobalt
bits are even tougher, but the costs are unreal.

This being said, a good machinist can sharpen and resharpen a high-speed
steel drill dozens of times in it's life. Of course the coated bits cannot
be sharpened. It's like a Ginsu knife; sharp as hell, but don't damage the
edge or it's over for good.

While we're on the subject, buy a can of Cool Tool (the pros use it) and
extend the life of all your cutting tools by many times, while speeding up
operations.

As for me, I use Sears Craftsman Titanium Nitrile coated bits.
