Eagle Rock Knurling Tool from Enco
 

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?

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.

Kent,

Thanks for the feed back and I'll probably go for the small one that's on
sale. Eagle Rock does make two sorts of scissors knurlers (besides maximum
diameter) and I should have made that much clearer than I did. At the risk
of getting too link happy, here are the two types from Eagle Rock's web
site:

which I think is the one that Enco has on sale, and

http://www.eaglerockonline.com/KNURLCRAFT/A144.htm

which is apparently their newer, 21st century tool and is available in
standard and up-to-the-shoulder styles. Beyond that I'm not sure what's
different between the two. Maybe they are phasing out the older one.
Mostly I was wondering if the newer style was worth considering.

I have that Eagle Rock knurler. I've been very happy with it. With
a little practice, you get so you know how much to tighten the nut
for various materials to get a good knurl every time.

Yes, the knurls are replaceable, and it's easy to change knurls for
fine or coarse and diamond or straight knurling.

I have one if the Eagle Rock knurlers from about 6 years back. It was
basically unusable until I put it through my surface grinder. As received,
the joint surfaces were so rough that they locked up if the pivot bolt was
tightened enough to take up the slack. It works OK now, but if I had it to
do over again, I would spend more money and get one I didn't have to repair
out of the box. Perhaps the current version is better, but be prepared.

Mike,

From what know of Eagle Rocks customer service if you have a problem w/ what
you get, call them and they will make it right. I cannot say this strongly
enough, their reputation is their living, they will make it right.
O'Brian's experience is good intel but he should have called them and raised
hell.

That's two for and one semi-against. I'd thought that Eagle Rock was one
of
the best clamp type knurling tools available but maybe not. I should find
out in a few days as I just ordered one.

I would not get the up-to-the-shoulder style unless I explicitly
needed to do that form of knurling. Note that the pin is supported on
only one side (to clear that shoulder), while the other on the same page
is supported on both sides of the knurls. The thicker side contains a
setscrew to hold the pin in place, BTW, to allow changing knurls. And
the kurls are a standard size.

When the pin is supported only on one side, there is more chance
of the pin tilting over time.

I have another style of Eagle Rock knurler. In mine, the clamp
pressure bolt is between the pivot of the arms and the knurls, with no
projection behind the pivot. It works well on a larger machine, but
gravity wants to make it droop when it is clear of the workpiece.

Mine looks more like this one:

http://www.eaglerockonline.com/KNURLCRAFT/A134.htm

and it was purchased from MSC, where it happened to only be labeled
"Made in USA", not labeled by the maker's name. Once I received it, I
discovered that it was an Eagle Rock knurler.

And at that time, a representative of Eagle Rock read this
newsgroup, and sent me a catalog of all the styles which they had at the
time.

But these days I more often use either a T-bar knurler, which mounts in
the turret and feeds on over the end of the workpiece, or an Aloris BXA
size knurler which has two arms on a dovetail which are moved by a
leadscrew connecting them with a left-hand thread on one end and a
right-hand thread on the other.

And I now also have a turret mount cut style knurler, which is
nice if you want the OD to remain constant. (Normal roll knurlers make
the knurl stand a bit proud of the original surface.)

Enjoy,
DoN.

Mine is at least 10 years old, never had that problem.
