SPARE PARTS FOR SIGMA TILE CUTTERS: THE COMPLETE GUIDE TO MAINTENANCE AND REPLACEMENT

In the world of professional tile installation, every cut must be clean, accurate, and chip-free. Sigma tile cutters are a favorite among experienced tilers and construction professionals thanks to their reliability, durability, and build quality. But even the best tools, when used daily and intensively, need attention. That’s why understanding the available spare parts—and knowing when and how to replace them—can make a big difference in terms of productivity and work quality.

Why spare parts matter for Sigma tools

If you use a Sigma tile cutter every day, you know that it becomes almost like an extension of your arm. But because it’s constantly under mechanical stress, used on hard materials like porcelain stoneware, and transported from site to site, some wear is inevitable. It’s not a matter of if something will wear out, but when.

This is why it’s essential to stay ahead of the problem with regular maintenance and by keeping the most important spare parts on hand. A worn cutting wheel or a stiff sliding carriage doesn’t just slow you down—it can lead to inaccurate cuts, damaged tiles, or costly delays on the job.

The most common Sigma spare parts (and why you really need them)

Among the most frequently replaced components, scoring wheels are at the top of the list. These small but vital parts are what score the tile surface before snapping. Regularly replacing the scoring wheel helps maintain clean, consistent scoring and reduces the risk of chipping.

At GLS72 we offer different types of wheels in differen sizes: the 12 mm is ideal for light-duty work, the 15 mm is great for everyday use on standard tiles, and the 19 mm wheel is perfect for tougher materials like thick porcelain. All wheels are made from tungsten carbide, known for its hardness and long lifespan. On our website you can also find the titanium scoring wheel, suitable for various Sigma tile cutters.

Whether you use your cutter daily or occasionally, keeping an extra scoring wheel in your toolbox is always a smart move.

The carriage—the part of the cutter that holds and moves the scoring wheel—is another critical component. When the carriage starts to stick, wobble, or feel loose, it’s time to take action.

If you are looking for a fully assembled replacement carriage for your Sigma Kera-Lift, you’re in the right place. The Carriage Kit comes complete with 2 wheels and 2 opening feet. It allows the movement of the frame in an easy and safe way. The kit is ready to be installed in minutes without needing complex disassembly.

A secure tile is a precise tile. That's where clamping knobs come into play - especially when working with heavy or slippery surfaces. If the knob becomes stripped, cracked or hard to adjust, your tile might move during scoring, which compromises the final result. 

We recommend the Clamping Knob Lever 108621 M8X40. This genuine Sigma part ensures a strong grip and smooth tensioning. It is designed to maintain secure pressure without damaging the tile surface, and its ergonomic handle makes tightening easy and comfortable. It's a small part, but it plays a big role in both safety and accuracy.

Let’s not forget the small yet essential accessories and hardware—knobs, handles, side supports, anti-slip feet, tension springs. These might seem minor, but when one fails, you’ll immediately notice how crucial it was. Sigma offers high-quality original spares that fit seamlessly with your existing equipment and help you keep working without interruption. On GLS72 website you can find the one that suits you the best, like the Professional Knee Wrap with silicon rubber strap.

How to find the right spare part

A common question among Sigma users is: “How do I know which spare part fits my machine?”

The answer starts with this: every Sigma machine has an identification code. It’s usually printed or engraved on the tool body, near the guide bar or on a label.

Once you’ve found the code, you can:

  1. Look up the user manual for your specific model (many are available online);
  2. Compare product images of the spare part with your damaged component;
  3. Contact GLS72’s customer care who will help you choose the right component for your tile cutter. All you have to do is writing an email to info@gls72.eu and an operator will reach out to you.

Keeping this information handy—and perhaps stocking a few key spares—can save you valuable time when something wears out.

Preventive maintenance: your best investment on the job

Replacing a part only when it fails is a risky habit—especially on a busy jobsite. Preventive maintenance is smarter and safer. For example:

  • Replace the cutting wheel every 2–3 months, depending on use;
  • Check the carriage and guide rails every 6 months;
  • Keep springs, knobs, and rubber feet in your toolbox as backup parts.

Spending a few minutes on maintenance can save you hours of downtime, and ensure every cut is sharp and professional.

Practical tips for replacing Sigma spare parts

In most cases, replacing Sigma spare parts is straightforward. Still, here are a few practical tips to help you do it safely and efficiently:

  • Work on a clean, stable surface to avoid losing small parts or damaging anything;
  • Refer to your machine’s manual—many include step-by-step diagrams;
  • Use the right tools, such as Allen keys, needle-nose pliers, or precision screwdrivers;
  • Never force a part into place—if it doesn’t fit easily, double-check the model;
  • Once installed, test the carriage or scoring wheel movement to make sure everything runs smoothly.

With a bit of practice, maintenance becomes part of your workflow—and your Sigma cutter will reward you with years of top-level performance.

In conclusion...

Wheter you're a veteran tile setter or just getting started, staying on top of cutter maintenance is one of the best ways to protect your tools, and your results. A well-maintained Sigma cutter not only works better, but helps you deliver professional results with less effort and fewer mistakes.
