Comments on: DMT’s Dia-Flat Takes a Crazy Beating

I may not receive an answer as this post is somewhat old. But, how is everyone’s Dia-Flat plate holding up? I am considering one for waterstone/oilstone flattening. My X-coarse Duo-sharp is running a little light in the grit now a days and may need to retire to flattening only my highest grit waterstones. I personally wish the Dia Flat lapping plate came in a finer grit as 120 micron is far too coarse for my fine waterstones 8000 and above.

Is there any risk of ‘contaminating’ my shapton glass stones if I also use my dia flat on my oil stones (which are polluted with oil and kero)?

Used mine today to flatten my waterstones. Best piece of sharpening equipment I’ve ever bought and I own quite a few including other DMT products. This is by far their best yet. Glad to see I’m not the only one using it for grinding as well. Thanks for the great review Chris. And for those worried about scratching the finer grits just do it. I find the scratches a good way to keep an eye on flatness as they wear off in use. Even if they do make a slight difference to the speed of cut (I didn’t notice) the speed that the dia flat flattens far out weighs any problems from a few small scratches in a fine stone. The scratches may actually be benificial anyway when you really think about it.

Chris,

In your first post regarding the DIA-FLAT, you stated that you use this on all of your Shapton stones. What is the grit range that you have tested, (low – high)?

Will I eventually regret using this on an 8000 Shapton? Too course?

Thanks,
Doug

Chris,
I just got my Dia-Flat and the instructions say to only use water as a lubricant. I am trying to stay away from water. I was curious what you use when you flatten oil stones on your Dia-Flat?

The 100,000 mile review is much more useful and informative than a review done on a brand new model. When my Shapton plate wears out, I’ll keep this in mind.

Thanks, Chris

I wish they made one in a slightly finer grit, say, equivalent to their coarse or extra coarse diamond stones. The Extra-extra coarse seems like over kill for flattening higher grit water stones.

I have the dia-sharp extra-extra coarse and I only use it to flatten my lower grit water stones. Being that I only use it on water-stones it has lasted very well for me, and it seems that it has hardly lost any grit at all. So if that is all anyone will do, I really don’t think you need the dia-flat.

I also have the dia-sharp coarse which I used for flattening chisel backs, plane bottomes, as well as finer grit water stones, and that thing is almost completely worn out.

As I a said, if I could get a slightly finer grit dia-flat I would. I like the idea of being able to use it on anything with no worries. I still think that a quality lower grit water stone is quicker than a diamond stone for flattening backs of chisels etc.

lllars, if you used the Dia-Flat to touch up an iron, you’d certainly want to follow up with finer stones. I would personally move to a 1000 grit waterstone, and then finish with an 8000 grit waterstone, on any chisels and hand plane iron, which provides a shaving sharp edge.

Hope this helps answer your question.

That’s very impressive and encouraging to hear. As well as my iWood is holding up on waterstones I’d be afraid to use it on my oil stones for fear of wearing it out. I am very excited to hear that this stone is holding up so well. Definitely, makes the price look much more reasonable. Thank you for breaking your silence.

The 95 and 120 micron Diamond Lapping Plates from DMT are superior diamond stones. They’re meant for lapping waterstones but I know people use them on oilstones as well and that will reduce their lifespan. I’ve been selling them for a year and a half with no complaints. I sharpen daily too and use them on my own stones. I’m impressed especially with the SIZE of the stone which is 4″x10″. I used to use the D8C which is an 8″x3″ stone. 24 sq. in vs. 40 sq. in.! I use the Shapton DGLP as well but they’re really only for the Shapton waterstones and are twice the cost of a DMT Lapping Plate.
