Heirloom Sintered Diamond Wheels

I really like these Heirloom Sintered Diamond wheels and can’t recommend them enough. I’ve been using them pretty much every day for the last month and a half, and they’ve been awesome.

I know the common consensus is that sintered wheels are less aggressive however that hasn’t been my experience with these wheels. The 80 grit is pretty aggressive and cuts more like a 60 grit electroplated wheel. It’s great for quick material removal when I’m shaping rocks or knocking down high spots and can power through any rock. The 220 grit feels closer to an 80 EP wheel to me. It still takes material off at a good pace but works nicely for smoothing things out before finer grits.

Both wheels are extremely well balanced (I can’t emphasize that point enough). No annoying vibrations or having the try to find the “sweet spot” like I’ve had to for multiple Galaxy wheels. I can take them off and however I end up putting them back on they’re perfectly balanced.

After grinding every day for a month and a half, they still look and cut like new. No glazing or wearing down noticeably.

In my option, they’re worth every penny. Especially since they’re only about $10 more than a Galaxy wheel and will last at least 10x as long.

If you’re on the fence, just get them. They’ve quickly become my favorite wheels.

This wheel is very very nice. You can search the interweb and you probably won't find a better price than Kingsley. This wheel is an investment and likely will last me the rest of my life. It's fairly heavy but perfectly balanced. If you are considering a sintered wheel DO IT. It's absolutely worth it.

Ordered the 80 grit after having the 220 for over a year. its not cheap but it works really well. Balanced and incredibly smooth to cut any stone with, one word of caution is to watch how soft of a material your grinding, it can disappear fast. Highly recommended, as is the 220.

I bought a 80 and 220 for my 6 inch Cab King, they last a long time. One thing I like best is after shaping on my 80 grit, the 220 grit does a beautiful job of smoothing out the waves, better then the 220 wheel by diamond pacific in my opinion, it has extended the life of my 280 Diamond Pacific wheel greatly. I am extremely happy.

These wheels are amazing for the price. Beautifully machined, well balanced, and smooth cutting. I have the 8" in both 80 and 220 grit, and they pair perfectly. It is an easy and relatively fast grind on the 220 to remove the scratches and refine the shape left by the 80. I also have a a few sintered wheels from other manufacturers, and some seem to have a higher concentration of diamond, (and price) but they don't really cut any better. So my conclusion is that the diamond in these wheels is sharp and free cutting. I can't speak about their ultimate durability yet, as I have only put a few dozen stones (agate, jade, opal, jasper, and tiger iron) through them so far, but short of using a micrometer, I cant see any wear, or change in cutting action.

I would say that a slightly coarser wheel would be nice for doing bulk removal and roughing in harder stones might be nice, but as always, there are trade offs with chipping and sub surface fractures.
