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

The best one ever

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.

Arrived in ample time. Haven’t used yet. Concerned about clamping force adequate to grip wire without slipping loose. Will have to wait to see and will follow up with comment following use.Setup and used briefly; satisfied with the ease of stringing the wire and satisfied with the grip-force of the clamps for the wire. Handles easily. The wire does cut with little effort and I will be looking into alternate sizes of wire that might apply for other, different tasks. Good job!

Cheap product. Handle fell off after 30 minutes of use

Well made easy-to-use

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.

Muy bueno just lo que buscaba

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.
