Sigma - Spare part for 7F / 2G / 2B3 - Carbide scoring wheel Ø 12 mm

The Sigma Ø 12 mm tungsten carbide scoring wheel is the original part for the Standard 37 cm, Tecnica 37 cm and Tecnica 66 cm pull tile cutters. It comes complete, ready to fit on the handle.

It is the wear part of the tile cutter: replacing it restores a clean, continuous score and a sharp snap along the line.

When to change the scoring wheel

Sigma does not publish a service life for its scoring wheels. In practice, it is time to replace it when:

• the score line becomes irregular or broken;
• you need to press harder than before to get a line;
• the tile breaks beside the score line;
• the wheel turns poorly or has play.

For a longer service life, the Ø 12 mm titanium scoring wheel fits the same models. Our guide to Sigma scoring wheels and spare parts lists the wheel for each series.
