KAKA INDUSTRIAL Manual Ring Roll Bender PR-3 | 3 inch Min. Diameter Roller for 1/4 inch Round Bar and 1x3/16 inch Flat Bar | Hand Crank Design for Chandeliers, Plant Holders​

Rolled a pair or 4 1/2 ID rings using 1x1/8 A36. Simple enough! I used a file to cut a nick in the adjuster knob so I could count turns and get back to a previous point of adjustment. Very helpful. If you want to make multiple rings cut multiple pieces of stock and run them all through, one pass each before you adjust the knob. This is a low cost tool so don’t expect too much. If you are working around your house and need a part now and then it will do fine. If you are planning on using this tool to make money with it it will probably drive you nuts! I recommend it for the homeowner.

As some others have said: the pin for the handle doesn’t drive, so I had to use a bolt; the two piece handle (obviously for shipping) loosens (I used locktite but I might just weld it); the rubber handle doesn’t spin, so it is awkward when doing more than one piece; if you have to replicate a radius, you need to mark the adjusting wheel or something. None of these things would cost money if just engineered better.I fabbed a mounting bracket that I could clamp into my vise/vise stand. The dimensions happened to all work so I could turn the crank freely and position material without it hitting the vise etc. See pics.The instructions included are “spartan”. A QR code to an online manual and some tutorials wouldn’t cost as much in printing and be much more useful.All in all, for the price, a decent tool. But with just a few mods, it could have been so much better…

If your trying to make rings, this is want you don’t want. I tested them all, Baleigh, Woodward, harbor freight and Kaka.Only Kaka rolls straight 1/4” rods, I even rolled 5/16” but that puts a lot of stress on the unit and I don’t recommend.All in All it’s the best ring roller on the market. Take it from someone who has tried them all!

Came way to greased up. Quality isn't all there for a $100 but all and all I would buy again

It is a decent ring roller. Some thread locker helps the two part handle.

Fantastic, sturdy machine. Bends 3.8mm mending plates with ease!

It does what it was meant to do. Only one small detail... like others, I had to modify the handle. The length of the rod that attaches to the machine is too short. So, if one were to clamp the machine in a vise (what I did), there wouldn't be clearance to turn the handle. Otherwise, I'd give it 5 stars.
