I have a chance to buy a Dorian Tool knurler that cuts the knurl, rather than impresses it. The thing has 2 wheels that are mounted at an angle; you start off the part, then move the carriage to the left and it actually cuts the metal. It requires far less pressure than the impressing types, but probably more than the scissors type. It seems to do a nice-looking job, from my brief experiments.

What's something like that worth? I couldn't find it in the online Dorian catalog, the pictures didn't come up for me. The number on the toolhead is WDKH R (I assume that the 'R' means Right Hand)

Are these significanly better than the old-fashioned kind?

TIA: <<Jim>>

This isn't quite the same thing http://www1.mscdirect.com/CGI/NNSRIT?PMPXNO=1661972&PMT4NO=37546561 but it may give a rough idea of how much such things cost. ($623.)

Here's one for $1500: http://www1.mscdirect.com/CGI/NNSRIT?PMPXNO=16578817&PMT4NO=37546561

I picked it up at an auction a couple of years ago for $20.00. I paid the big bucks because it came with several sets of spare knurls. I use it frequently, and it works very nicely.

The Dorian works on the same principal and is a little cheaper if you have to spend the full price.

Jim,
The Dorian is similar to the SPI, except it's not adjustable. My buddy, who has the Dorian, uses one of those SPI jobs and speaks very highly of it. The one he uses sells for about $1000.00, or so he seems to think; it was $850 in a catalog that's a couple of years old.

Dunno if the thing needs to be adjustable or not.

Is this the knurling tool you are referring too?
This is a Dorian. Anything coming out of Dorian is expen$ive, and this is an example.
Notice the sale price here in Houston TX at Rex Supply. The catalog also has a closing date of Dec 31, 1999. What do you think they sell for today? Much, much, more I am sure! So, like another said...hang onto it because you have a fine item there.......pg

I have the Quick (Austrian) version of the same cut knurler. It's a work of art.

Jim, try a search of the archives. John Stevenson made a clone of the Dorian a couple of years ago. Maybe he will turn up with some information.

The adjustability is a help, but the main trick is the knurls themselves are different. They have a sharp edge to do the cutting, many standard knurls have rounded edges.

John has a Quick as well (actually, he's the one that turned me on to the Quick knurlers). I thought the clone he made used a single knurl wheel?

By the way, the advantage of the spiral gear driven wheel adjust is that you can knurl diameters much larger than a crush knurler. I have the VDI 30, and you can knurl a workpiece up to 250 mm (10") with the knurl wheels set at their maximum "helix" angle.

It would appear that you can knurl in either a right or left direction, simply bt rotating the head. The ad also says it cuts the thread as you said. Nifty tool indeed..........pg
