Never heard of it.  Internet web link??

Crimping RF connectors (PL-259 in example) on Coaxial Cable
http://www.bcdxc.org/pl259_crimp_on_connectors.htm

IF you are looking for proper CRIMP tools for RF connectors on Coax,
then the RF Industries Rachet Tool RFA-4005 with appropriate Dies is common.

IDEAL Industries Crimp Master is a similar crimp tool.
Home Depot use to stock this tool in their electrical section.

If you're referring to the K4AVU Coax Crimper that's used to crimp regular solder-type PL-259 connectors onto coax, I don't think that's a good idea.

Standard PL-259's were designed to be soldered, not crimped. The K4AVU tool essentially crushes the braid against the dielectric and this results in neither a good mechanical connection, nor a good electrical connection.

If you want to crimp, fine, just get the connectors and tools designed to do it properly. Look on the RF Industries web site -- they have everything you need to do it right. For the price of the K4AVU tool, you can buy a proper coax crimping tool.

Yes, I did mean K8VWU. I guess I can't type any more.  I wondered about crimping something that was not designed to be crimped.  Thanks for the comments.

I've always disliked the chore of assembling coax cables because of the difficulty of getting a consistently high quality result.  For some reason, even though I've been soldering for 50 years, and even with a good soldering iron of the correct wattage, I too often end up with stray solder on barrel threads, or a solder job that is just plain ugly.  

Since I'm in the process of putting together a complete new station with many coax fittings, I recently decided to try a switch to crimp-on fittings.  I bought 250 feet of LMR240 UltraFlex, a crimp tool and fittings, and I'm pleased with the result.  The crimp tool cost $28, BNC fittings only $3.00 each, and Type-N fittings $3.10 each, all from Amazon.com.  I bought nice quality silver plated PL-259 fittings from Richard East N5IAW@navcomusa.com, for very reasonable price of $2.53 each in package of ten.  Those prices all included cost of shipping.

I still need to solder the center pins of the PL-259, but that's a snap. So far, the results seem great, and the process of assembling coax cables has changed to a source of small enjoyment.

Here are links to the Amazon.com pages, if interested.
