Toyo Glass Cutter Head - TC21

Carbide is an extremely hard material that allows the cutting wheel to maintain a sharp edge for longer periods, enabling precise and consistent scores on glass without excessive wear.

The lifespan of the cutting head depends on usage frequency and the type of glass being cut. Signs that it needs replacement include skipping, chipping, or difficulty in scoring. Typically, with regular use, it may last several months to over a year.

No, this replacement head is specifically designed and manufactured for the Toyo TC21 and TC21PVR supercutter models. Using it with other models may result in improper fit or damage.

While not strictly mandatory for all types of glass or scoring, using a specialized glass cutter oil is highly recommended. Oil lubricates the cutting wheel, reduces friction, cools the glass, and helps achieve a cleaner score line, extending the life of the cutting head.

The Toyo Glass Cutter Head - TC21 weighs approximately 4 grams.

After scoring with the Toyo TC21 head, ensure the score line is continuous and smooth. Apply steady pressure along the score line with the breaking pliers or by tapping gently underneath the score. Using sufficient cutting oil during scoring also aids in a clean break.

Ensure the head is securely attached. Check if the carbide tip is clean and free of debris. If the tip appears dull or damaged, it may need replacement. Verify that you are using appropriate cutting oil and applying even pressure.

Confirm the correct type of glass is being used for the cutter. Ensure the carbide wheel is clean and has not been damaged. Apply sufficient cutting oil and maintain consistent pressure and speed during the score line.

Check for any debris or damage in the threads of both the head and the cutter body. Ensure you are using the correct head for your specific Toyo TC21 or TC21PVR model. Do not force the attachment; gentle screwing should suffice.
