Sigma Jolly Edge Grinder Attachment 37A3PD – Adjustable 35-55° Tile Beveling System

Create crisp, uniform chamfers on porcelain, ceramic, and natural-stone tiles with the Sigma 37A3PD Jolly Edge Machine. This grinder-mounted attachment lets you dial in bevel angles from 35° to 55°, delivering factory-smooth edges that upgrade the finish of backsplashes, countertops, and façade cladding.

Features & Benefits

  • 35°–55° Adjustable Bevel – Fine-tune the angle for subtle eased edges or bold 45° miters.

  • Full-Length Guidance Plate – Keeps the grinder perfectly square to the tile for a continuous, chatter-free chamfer.

  • Included Sigma 75B Diamond Wheel – 4½″ continuous-rim blade supplies clean, chip-free cuts out of the box.

  • Quick-Lock Height Dial – Set the cutting depth in seconds to match tile thickness from 6 mm to 20 mm.

  • Rigid Aluminum Frame – CNC-milled body resists flex and dissipates heat for long grinder sessions.

  • Universal M14 Thread – Mounts on most 4½″–5″ angle grinders (grinder sold separately).

More Details

The Sigma Jolly Edge Grinder Attachment 37A3PD transforms a standard angle grinder into a precision edge-profiling station. Simply thread the body onto an M14 spindle, set your desired angle with the clearly graded dial, and glide the 8-inch guidance plate along the tile. The result is a consistent bevel line that looks factory-machined, eliminating the risk of uneven hand-held passes that can chip expensive porcelain or natural stone.

Supplied with a Sigma 75B continuous-rim diamond blade, the 37A3PD excels on hard porcelain panels, large-format floor tiles, and stone skirting boards up to 20 mm thick. The rigid aluminum frame absorbs vibration for smoother operation and longer diamond life, while the quick-lock depth knob lets you match the wheel height to any tile thickness in seconds. Ideal for installers, fabricators, and remodelers who want upscale, mitred corners without investing in a full wet-saw miter station.

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.
