Mike,
The difference between the two Eagle Rock knurling tools is the diameter the
tool can knurl.
The less expensive tool will do 0-2 1/8" (I have one of these) the more
expensive will do 2"- 4".
The knurls can be changed by pressing out a pin that acts as the axel for
the knurl, I have done it many times with a 3/16" pin punch and a bench
block.
If you use Armstrong knurls and this knurling tool any problems you have
won't be the fault of the tooling you are using.
I bought mine several years ago for the price of the larger tool and it has
been worth every cent.

I'm not too happy with the no-name import scissors-type knurling tool I'm
currently using and am considering an Eagle Rock from Enco that is on sale
for $95:

Eagle Rock apparently sells two different types of these tools - the one
above and another that is a bit more expensive. Has anybody here used the
cheaper one that is on sale and is happy with the purchase? Are the
knurls
replaceable and if so, what is a good brand of knurl to buy?
