1PC Coping Saw Steel Frame With 0.5mm Diamond Wire Saw For Wood Stone Metal Cutting Multi function Hand Tool

Tricky to setup but once the wire is tightened with a wrench then it doesn’t budge when sawing through steel. Took no time at all to cut a few millimeters precisely in the spot I wanted to cut.

The best one ever

Diamond wire is way tougher......

It didn’t have any wire with it

Nice value!

I purchased this twice, once through my job to cut neodymium-iron-boron magnets and once for home to cut ceramic tile. In both cases the cutting progressed extremely slowly. The magnets are a hard material, but that is why I chose diamond. Using a 1-mm wire to cut a 3/4"-thick magnet stack, after an hour of sawing, the slot was about 1 mm (0.04") deep. It was generating sawdust at about the same rate after an hour as in the beginning, so the problem was probably not rapid dulling of the blade. A standard hacksaw blade cut a 1/4-thick magnet at a rate of about 1/4" per hour. At home, I tried to use a new saw to square an inside corner in a ceramic tile. (A 1/4" radius was left by the diamond angle-grinder used for the cuts.) I quit after 10 minutes of sawing. In this time, it had cut a groove perhaps 0.02" deep. I did the job with an aluminum-oxide sanding cylinder on a Dremel tool in about 10 minutes. The saws are useless for my applications, but I gave two stars instead of one because they did cut and perhaps would work for other applications. My guess is that either the grit is much too fine for a 1-mm or 0.6-mm saw or the grit contains very little diamond.

Well made easy-to-use

The good thing is the saw itself seems decent and I mean the frame of the saw. It even arrived a day sooner than projected. However, and I emphasize maybe, maybe you could cut wood with with this although I didn't try. I did try on a geode which would be no denser than stone on the outside and Jade on the inside. It was cutting neither. It left a lead like mark where the wire attempted to look like it was sawing through, but that's it. In fact most of the dust I saw after I used it, had to be the quote unquote diamond coating that supposedly made this a diamond cutting blade. After a few passes, the wire was smooth and had no texture to it whatsoever. I even used all sides of the wire thinking that maybe just one side was loose. I wore the wire down smooth as if there was no coating on it whatsoever. I haven't tried to see if plastic or ceramic tile is less dense and could maybe be cut with this without it just stripping the coating off the wire, but I wouldn't get my hopes up. I am always skeptical about reviews that have no details, since people can pay to have people review products and their sites. I wanted to ensure people that I wasn't paid one way or the other for this review and wanted to give details so the buyer could beware. Again the soft frame is a nice adjustable hand saw frame. Just don't get hopes up that you're going to cut much of anything with the actual wire.
