More Details

If your cutter rail has play, the rail end support is a common wear point—especially on jobs where the tool is moved frequently or used for thick porcelain. Replacing the Support Screw 15 helps re-stabilize the rail, which can improve scoring consistency and reduce the chance of uneven pressure during a pull cut. It’s a practical maintenance part for keeping Sigma 3L and Series 3 cutters running like they should. Confirm rail width before ordering, then install and adjust to ensure the rail sits square and steady.

Tile tools 🔥

Tile tools sent this package out fast! I haven't opened the box yet. Infact, there's a few tile cutters sitting unopened in the garage.
It's a healthy addiction.

GEORDI is the BOMB

I cant think of any product better than Ardex (first sealer, then the epoxy in "black licorice" (the color will be a point later). WAIT, I can think of something better....CUSTOMER SERVICE!!! I had a problem with my 3rd order...on one phone call Geordi handled it. He and I spoke/exchanced some photos....and in about 34 hours the replacement was at my front door.

NOW here's the interesting aspect. I used "black licorice" epoxy. Where I had to stop I had about 1/3 container left. Rather than letting it harden, (it was going to waste anyway) I got the idea to "fill in divots in my 50 year old blacktop drive way". When I have it sealed I do ask them to "fill in" holes that have developed....but they are NOT going to sit and patch it with a putty knife like I did with the Ardex expoxy. It's been maybe 2 months.....WATERPROOF, adhered like welded steel. Only diff is a slight color variation....and next year when I have a blacktop seal put over....you will NEVER see it. I over-ordered....and I will literally use every bit to seal every crack that I can find, so water does not freeze/crack it further!

Great Product! Had stubborn water stains on my stone tile floor after removing my hot tub and stone pro scrub did the trick after a couple of scrubs.
