Ok, but very useful nonetheless

The Cleaner the demill, the easier the build and better end result. The problem with 'Normal' drill bits, they have a tendancy to walk, can be difficult to judge if your centered up without time consuming indicating with a dti. Also, trying to use a smaller starter drill when dealing with these 'small' diameter bits can lead to the bit flexing or snapping. Whats the solution?

Stepdrills!!! These are easier to use, produce better results and are much faster. A drill bit is still the fastest way of removing material from a hole. With these step drills you get several advantages. The bit effectively has a pilot hole for each hole made so bit "walking" is virtually eliminated, since the step is short it's supported much more rigidly than any bit of equal diameter ever could be and the size of the 'pilot drill' is very small which produces a tiny pin ***** type witness mark which has its own advantages. A small witness mark lets you see if your on center before finding out half way threw your not. Also, with such a small witness mark, if your off and need to readjust there isn't a big divit that makes the bit want to walk back and deflect into the previous start mark.

I have a machinist buddy w/ 40+ years in, as the years pass he has slowly let me buy his tooling, tools & a few machines. Kinda sad because I know what it means but so is life. His stuff is high quality, well maintained or new.

This was bought long ago and is a limited supply. When it is gone I won't be getting more. I removed the protective coating to take the pics - yours will come coated like the pic shows. These are NEW, never used speciality bits made in the USA. Not cheap import regrinds. Anyone who knows the saying, "the machine is the cheap part" knows how God awful expensive good tooling is. Get them at an excellent price while they are availible.

The right tool for the right job!!!
