D8X 8-Inch Dia-Sharp Continuous Diamond Extra-Coarse , Grey

Good solid diamond stone that took a lot of abuse flattening sets of Narex chisels and new plane blades properly so I could keep them sharp on finer stones. Cuts nice and fast and keeps doing it, also great for flattening out your finer grit water stones with.

This is great. I got this mainly to flatten my Japanese water stones (double sided rough and medium, plus a 12000 grit honing stone) and it's great for that. I've also used to to dress some plane bodies and it still works great on the stones. Should have bought it years ago as the hassle of using glass and paper have meant I've mostly made do with hollowed stones...

used the 8000 grit extra extra fine a good few times and no problems so far,reports of some failing after little use seem to point to hit and miss quality,puts a nice polish on the edge of knives

Good price for DMT extra coarse.If you want to stop using a grinder, this is the diamond plate to buy, provided you also have coarse, fine and super fine plates. Or if you only use carbon & A2 steel blades and want an extra coarse to cut bevels, using oil stone and strop for the rest.

I bought the extra course plate as I restore a lot of abused tools.I put a primary bevel on 2 plane irons using light pressure and water to float off the swarf.When I had finished the centre of the plate was worn down to the metal.I get several weeks of use from a cheap plate. I got 10 minutes from this one.

Liked the thickness of the plate; good for flatening of stones.

Buona fa il suo lavoro

Düzlük konusunda mükemmel Alüminyum oksit Seramik taş düzelmek için 220 grid aldım aldım. Taşları düzeltme konusunda ilk başta hızlı fakat şert seramik taşları düzeltirken çabuk keskinliğini kaybetti. Tavsiyem 120 grid versiyonu alın yada kullandığınız yumuşak bağlastirici seramik taşlarda kullanın. Ayrıca kesinlik reçine bağlastiriciniz elmas taşlari varsa bu bu elmas plaka ile düzeltmeye kalkmayın elmas plakaniz cöp olur haBileme kısmina gelirsek : çok agresif fakat iyi bir seramik taş kadar uzun ömürlü olacağını düşünmüyorum.

works well

This is fantastic and removes metal aggressively. It works well when I need to set the bevel or lap the back of my tools. This saves me time and effort compared to sharpening on my previous water stone.

Sharpening has three steps... 1. Getting the right shape/angle on the blade, 2. Sharpening to a very fine edge, 3. Honing from very sharp to extremely sharp.This extra coarse stone is great for shaping the blade. For example, I have a kitchen knife that was messed up by a grinder - the middle didn't touch the cutting board. In just a few minutes this extra coarse stone straightened the blade and got a good bevel along the length. It still needed to be sharpened with the DMT Coarse and Fine, but with the cutting edge of the blade straight and the bevel good, sharpening was quick and easy. Example 2. I have a 1 inch woodworking chisel that I had messed up on a grinder (bad angle). I had spent a huge amount of time (over an hour) with a coarse DMT stone getting it partially fixed - from a crooked 30 degrees to 28 degrees. Now that I have the extra coarse, I got it to the desired 25 degree bevel in minutes rather than hours. Yes, it took quite a while, but nowhere near as long as I had already spent doing the first part of the job with the coarse rather than extra coarse stone.Some of the other reviews said the plate was not flat. When it arrived I immediately compared it with my three other DMT diamond plates. The plate was flat (or I would have returned it). As I first used it, I could hear a slightly different sound the first time over each area of the stone. No surprise, it had to be broken in, so I made sure I covered the whole area. A couple small spots were still rough after the first pass, but were perfect after I ran the chisel I was sharpening over that spot 3 or 4 times. No big deal.Overall I highly recommend the DMT extra coarse for shaping a blade (kitchen or woodworking). Much less likely to mess it up than on a grinder (or in my case, I was able to fix the blade after messing it up on a grinder)The DMT regular coarse is excellent for the first sharpening - removing the scratches that naturally come from using an extra coarse stone. I originally got this coarse stone to flatten my waterstones - it does a good job of that, but is useful beyond just the waterstones, when I have to do serious sharpening work on a neglected blade.The DMT fine (there is no medium) does a great job sharpening kitchen knives (at least razor sharp), and taking my chisels etc to the next level. If I am just touching up a sharpening job, this is where I start. Kitchen knives rarely go beyond this level.The DMT micro fine was a disappointment for my chisels and planes. Instead I go to waterstones - 4000 grit then 8000 grit. Those give an almost mirror finish to the chisels. I called it a mirror finish until I got a 13,000 grit waterstone. Now that is my standard of sharp, for both the front and back of my blades.
