Common Sigma Cutter Parts That Need Replacement

Here are the most frequently replaced parts on Sigma tile cutters, based on real-world installer experience:

• Scoring Wheels: Essential for smooth, accurate cuts. Wears down over time and must be replaced when scoring becomes inconsistent.
• Handles: Push or pull style. Can loosen or wear with heavy use. Ball bearings inside the handle assembly may also need replacement if the handle becomes too loose on the rail.
• Breaker Feet: Critical for clean snap cuts. Replacement recommended when worn or damaged.
• Guide Bar & Measuring Bar: Ensures straight and accurate cuts. Prone to wear with repeated heavy use.
• Clamping Levers: These levers often break or go missing and are an easy part to replace.
• Clamping Lever Nuts: Frequently lost — a simple but important replacement part to keep on hand.
• Table Springs: These wear out over time and generally require replacement about once a year for optimal table tension and cutting performance.
• Clamp Knobs, Rip Guides, Accessories: Smaller components that enhance precision and workflow. Subject to wear and occasional replacement.

Tip: If your cutter no longer tracks straight, delivers inconsistent results, or parts feel loose or misaligned, inspect these components first.
