Frequently Asked Questions

Q: Which cutting head angle should I choose for standard window glass?

A: For standard window glass, which is typically 3–6mm thick, the 140° or 145° replacement cutting head is the best choice. The 140° head suits 3–8mm thickness and the 145° suits 5–10mm, making either ideal for most common glass panes.

Q: Are these glass cutter replacement heads compatible with all cutting machines?

A: These replacement heads are designed for use with standard glass and ceramic cutting machines that accept a 4mm shank diameter. We recommend verifying your machine's shank size (4mm / 0.2 in) before purchasing to ensure a proper fit.

Q: How long will these cutting heads last?

A: Thanks to their high-carbon steel gasket and alloy construction, these replacement heads are built to be wear-resistant and corrosion-resistant for extended use. Longevity depends on frequency of use and the materials being cut, but they are designed for a long, reliable service life.
