Zenesis Resin-Filled Diamond Cup Wheel – 4 in., Medium 80/100 Grit, Wet or Dry
Zenesis Resin-Filled Diamond Cup Wheel – 4 in., Medium 80/100 Grit, Wet or Dry
The Zenesis Resin-Filled Diamond Cup Wheel is a 4 in. medium 80/100 grit diamond cup wheel for wet or dry flat grinding of granite, quartzite, marble, engineered stone and porcelain on an angle grinder.
Medium sits between the coarse and fine grades and is where most edge shaping and levelling is done: it still cuts, but leaves a surface the fine wheel or the first polishing pad can clean up quickly. The resin filling the spaces between the diamond segments gives a near-continuous face, so the wheel grinds without the swirl marks and chatter an open-segment turbo cup leaves, and Zenesis balances each cup to keep vibration down. Zenesis has increased the diamond and metal-bond segment content in the current version for longer life. It is a grinding wheel, not a polishing pad: it takes stock off and leaves a flat, even scratch pattern for the pads to follow.

Who Is This For?
Fabricators flat-grinding slab faces, edges and slab backs before lamination, and installers removing lippage, who want a smooth resin-filled face instead of a silicon carbide stone. The line comes in three 4 in. grades: coarse 50/60, medium 80/100 and fine 120/140.
Frequently Asked Questions
When should I use the medium grade?
After the coarse wheel has removed the bulk, for shaping and levelling. If you are only cleaning up before pads, go straight to the Zenesis Resin-Filled Diamond Cup Wheel – 4 in., Fine 120/140 Grit, Wet or Dry.
Can I use it dry?
Yes. Zenesis rates the resin cup wheels for wet or dry use. Wet keeps the resin cooler and the dust down; dry is fine for short site work.
What thread does it mount on?
Zenesis does not publish the thread on its product page. Distributor listings for this part number give 5/8 in.-11, the standard angle-grinder thread; confirm against your grinder before ordering.
Does it work on porcelain and Dekton?
Yes. Zenesis lists porcelain and Dekton (approved) along with granite, quartzite, marble, engineered stone and concrete block.
What does resin-filled mean?
The gaps between the diamond segments are filled with resin, giving a near-continuous face. It grinds smoother than an open turbo cup and leaves less swirl and scratch to polish out afterwards.
