I have owned and used 6-7 diamond wheels/cups. Found one that trumps them all. The diamonds do not look much bigger but this wheel cuts agate like butter be it dry or wet. Even with very light pressure. It is running fast at 3600 RPM and dead smooth in my $90 tile saw. At 1/4" wide it barely fit in the tile saw groove. Apparently the diamonds are the sharpest of all wheels so far. Guessing they are crushed octahedrons. Cutting rate must be X8 faster with less pressure. Nothing like it, and was not expensive. More big ones to be ground: How they look dry, note bottom one with bleached coating and pits left on top: wet, getting ready to finish bleach spot on bottom. Top round one looks to be palm and very nice: All one to two pounds. Small enough to polish 3 at a time using dividers in Vibrasonic. But they will be tumbled in rotary separately in small barrels.

Looks like it works great! Although they will be gorgeous tumbled, there are some that would be wonderful slabbed and cabbed!

I'll look it up on Ebay purchases. It is a 7 inch tucking blade(for removing mortar). The first diamond blade that ever made me bleed with a very light touch. This thing is sharp. No surprise, sharp is the game. And this one takes very little pressure on the rock which makes it way safer. This is a 5 inch tuck blade and is useless. Even pressing down hard on the rock. Removes 5-10% what the other tuck blade does for much more effort. Less pressure means way more grinding control. Faster coverage. Safer grinding. This one, diamonds look the same with the naked eye. Drag your finger on it, you can feel the difference: www.ebay.com/itm/7-x-250-Tuck-Point-Diamond-Blade-for-Mortar-Concrete-Masonry-/121905745807?hash=item1c62260f8f:g:-5oAAOSwa~BYVJSj

Removed over an 1/8 inch over the whole ~2 pound stone in 5 minutes. Dry.(two fans and outside to remove dust, silica poisoning is for real) The side has the sharpest diamonds. Same with the 5 inch tuck wheel, it does not grind as fast on the face as the side. No explanation for that. My home made grinder runs at 2100 RPM and shakes a bit. The tile saw motor is dead smooth and faster at 3600 RPM. No pulley/v-belt/extra shaft. Plus it is 1/2 HP, twice as powerful as home built. Dust cloud galore, good thing. Better if the blade would raise higher for bigger rocks. May have to do some surgery on the tile saw for better blade access.

Wow that is a fat blade for sure. It looks like it would eat those rocks up. At first look I thought I bet that one will cut you, I see it did. I can't wait to see those tumbled. Very Nice

Beware, the diamonds in a tile saw blade are much finer to avoid chipping the glaze coat. This tuck blade is not for finish work but for removing mortar in mass between bricks. Like most of the diamond wheels I have used. This one is different though, in the sharpness dept.

Very Nice Several months back I was grinding larger rocks to tumble morerockspleaz. Using 5 or 7 inch diamond wheels. None of them ate rock like this one. Must have pre-ground 7-8 bigger rocks in the 1-2 pound range- www.flickr.com/photos/67205364@N06/sets/72157662746031090This wheel will be a game changer.

Man those are sweet jamesp . I love the idea of grinding faster and better. I have looked at the diamond cups but figured I would cut my hand off. I have a poly arbor to use for a super grinder. I like this idea.

this blade never had a chance to get tested. I mounted it on the tile saw 6 months ago. Turned it on and it sawed the cord in half. Cable under saw duh. fixed cord today. Cord repair:

I like this idea. Dirt cheap at $27 ppd BeLinda. All grinders dangerous. Cab machines bite too. Any finger close to a cutter = danger. However this is coarser and sharper, so danger escalates. Look at the fine dust on the tile saw table in the photo/post above. It shaves very fine particles, smooth and controllable. No knots in stomach. That rock on the table will be polished in 2.5 weeks or less. All 4 of them for that matter.

I bet you or I or someone could come up with some type of hand protection like a shield or guard. Just take some thinking time.

Yes that's kind of what I was thinking. Finger saver.

Sure see the value of cleaning up the rock before you tumble those big beauties. That crazy lace is a mess in places as is the coral. The proof is in the pictures.. Why dry on the sawing? To see the fracturing better?

That's awesome. I have a little time on my hands right now. May try to set up something. Grit and time saver. Makes sense.

Dry is less messy and easy. Use a direct fan and then the 42 inch greenhouse fan to evacuate dust. the cup is geared upward 1: 1.3 so about 2300 RPM w/1750 motor. Like the direct drive tile saw much better, no vibration. And more power and faster rpm at 3600
