6 inch Flat Resin Bond Diamond Grinding Wheel Grit 150 Concentration 100% for Carbide Metal Hard Alloy Tungsten Steel

I have been using "green" wheels to grind carbide. I noticed lately that the Weldun flat is less common and I burned my fingers when grabbing a 1/2" carbide end mill out of the v-block on the grinder and hoping to install it where a carelessly destroyed predecessor had been. Yup, was in a hurry grinding and got it quite hot. That's when I checked online to see what was available since I didn't have a good diamond wheel of my own for use in my own shop. Since I'm cheap, I went with this less expensive import. It is working well and I was surprised how much cooler the mills I've used it on were after giving them a .032 X 7/16" flat on the shank. So far the wheel doesn't show any wear, buildup or skip spots. I admit ignorance to exactly what 75% or 100% diamond means, but this wheel cuts very well and I believe it was called 100% and cost me a buck or two more than some listed as "75%". Most of the 5 or 6 shanks I have used this wheel on were C5 carbide. So, I'm quite happy with this wheel and I'm betting the 100% diamond is helping this wheel run as well as it does.DaveGx

I mounted the wheel on a 6inch bench grinder for grinding tungsten electrodes. I had to make a spacer for the bore size to reduce it to match the arbor on the grinder but I knew that when I purchased the wheel.

This is a good product and it's well made, runs true etc. zero complaints. Just thought that I'd share that I'm a beginner TIG welder and I purchased this wheel for the sole purpose of grinding a smooth point on 3/32" thick tungsten electrodes. It does this very well and the wheel began showing a wear groove fairly soon after using it. Albeit Tungsten is a very hard material and during the TIG learning process I've had to re-sharpen my electrodes more often than a proficient TIG welder would have to. Nevertheless, if you're getting this wheel for this purpose be mindful that it's a 3/8" wide wheel, so try to space 3 maybe 4 wear grooves across the face and it will extend it's useful lifespan (I didn't think ahead to do this) . Again no complaints, although I will likely try something different after this wheel expires.

Works awesome for stump grinder teeth sharpening. Takes about a minute a tooth for 700 green teeth

FINALLY now I can finish my star Ruby's :)
