SE 74330DF 6-Piece Flat Diamond Grit File Set - Multi-Grit for Metals, Glass, Stones - 7" Length, 2" Diamond Surface, Round Handles - Includes PVC Pouch

These worked much better than anticipated. Great value for the price.

I needed to file a rough edge on a glass measuring cup and needed these files to do the job.

These are quite nice, actually. The dimensions are a little off in the copy, but not by much. Overall length is 8 1/2", diamond length is 3 1/8", width is 7/16 or 11mm rather than 1/2", and thickness is 3mm or just under 1/8" rather than the 5mm stated. Files are sturdy, straight and flat (the coated area and handle being raised). The diamond coating is on all four sides and the tip, as if it were dipped - I mention this as sometimes it's useful to have one edge smooth on a file, though of course the edges coated are useful as well. The grit consistency appears to be uniform and consistent with the spec'd grade. The grade is not marked on the individual files, but that's easily rectified with a felt tip marker. The included vinyl pouch is workable though a bit chintzy - I almost mistook it for packaging as it was stuck to the cardboard. In very fine print on the package it reminds one to use with water or lubricant as one should not use these dry (as with most diamond files)..

Amazing how we can use diamonds as files, and not only that, it's cheap. I like to see the twinkling on the bigger grits.

small size is good for hard-to-reach areas. the fine file is good for dressing ignition points.

These diamond files have large abrasive surfaces and long handles, so they are comfortable for someone with average to large hands to use. The set fills a gap I have always had in my tool collection. I expect them to work well for initial sharpening of knives and other tools, for filing welds on steel assemblies, working with glass, ceramics, or stone materials. They provide a very wide range of grit from #40 to #600. The manufacturer paid much more attention to making these files useful rather than beautiful, which is fine for someone like me who plans to actually use them frequently. The plastic dipping on the handles is a little inconsistent, and the included case is flimsy but it should keep the abrasive surfaces from damaging each other. The set can be rolled up for storage.

I use this to sharpen my fabric scissors and its working so well!!!

Works very well

it was brilliant in a small tight space they are just the right size and being impregnated with diamonds bits it worked well i am very happy with this product will be using it for many years

Perfect all around

Like most of the SE files, I don't consider them top of the line, but they definitely work and serve their purpose for me. Haven't had an issue with them dulling yet from the diamonds falling off, but time will tell. First set of SE diamond files I almost sent back as initial impressions were not so good with the coating not covering as much of the file as I would have liked, but they have proven useful over time. I don't do a lot of metal work with them, so not sure the performance if frequently used on harder material but when I have used them on metals, it has been fine.

These diamond grit files are ideal for sharpening small tools. Side cutting pliers for example. They are small enough to get into small gaps. I use them on small workshop and garden tools. Ace!

only thing that would make them 5 stars is if the grit rating was put on each file. 240/400/600 grit are a bit hard to tell apart - make sure you keep them in order....
