Helix Vacuum Brazed Cylindrical Grinding Drum — 1/2″ × 2″, #140 Grit (Wet/Dry)

Shape tight inside radii, sink cutouts, and edges fast. This vacuum brazed #140 cylindrical drum (1/2″ × 2″) delivers aggressive, controlled stock removal on granite, engineered stone, porcelain/UCS, marble, and glass—wet or dry—with a safe max speed of 6,500 RPM.

Features & Benefits

  • Vacuum Brazed Diamonds — Single-layer, high-exposure coating cuts immediately on contact.

  • Tight-Radius Control — 1/2″ diameter reaches small curves other tools can’t.

  • #140 Medium-Coarse Grit — Fast shaping with a clean, uniform scratch pattern.

  • 2″ Working Length — True cylindrical cut for deeper profiles and consistent contact.

  • Wet/Dry Versatility — Run wet for longest life; dry for quick touch-ups.

  • Balanced Core — Reduced chatter and edge blow-out on brittle porcelain.

More Details

Helix’s vacuum brazed construction bonds a single diamond layer directly to the drum, exposing more diamond per square inch than plated alternatives. The result is rapid removal with cooler grinding, ideal for cleaning up saw marks, tuning sink openings, and sculpting inside corners on dense, high-silica materials.

At #140 grit, the drum strikes the right balance between speed and surface quality—aggressive enough to shape, refined enough to transition to finer abrasives quickly. Use with water to extend tool life and control dust, or make short, light dry passes where water isn’t practical. Always operate on a variable-speed tool at or below 6,500 RPM.

Tavy spacers

I've been using these spaces for years. I love them. I'm just a little nervous because they changed the color of the spacers. I think they were bought out so I'm not sure if they're going to be the exact same size. They changed The colors the white ones are now 1/16 instead of green they switched all the colors around. I'm glad I have all my old ones

Awesome!

The product worked great!. The effort to break off is much less than the previous product I was using from the orange store. These may cost a little more up front, but the ease of removal is worth it as I had a number of the previous products break off in between the tiles. And that can be a challenge to remove without damaging a tile edge. No doubt will purchase these again.

Outstanding Product

I have used the orange store brand and some clips were difficult to break and some remained between the tiles which can be a challenge to remove. With the perfect Level Master product, not one single issue. It takes much less force to break the spacer clip also. I will purchase this brand again without question. Good quality product and easy removal.

Better than Dewalt and MK Diamond blades for cutting porcelain tile

Before finding the Helix Copperhead blade, I used Dewalt XP4 and MK Diamond MK-415 blades. Both of these blades generally have good reviews, but they cannot touch the Helix Copperhead for smoothness of cut, lack of chipping, and lack of breakout at the end of the cut. I use the Helix blade primarily on porcelain tile and the cuts look factory on rectified tile. My machine is a MK Diamond 10" wet saw with a belt-driven blade arbor. The only non-positive comment I will make concerns the thinness of the blade. It has a thickened center section, which helps the blade run true. However, because of the blade rim thinness, it is possible for the blade to deflect slightly if pushing the tile too fast - an effect that is easily remedied by slowing cutting speed.
