Easy to carry and ideal for household tasks, cutting glass, diamonds, and minerals. Product Details: This glass cutter features a self-oiling system – when the diamond tip presses against the glass, oil is released automatically during use and stops when not in use. (Beginners may find it tricky to control the oil flow at first, which can cause leakage. We recommend practicing without filling the handle with oil initially.) For best results, lightly wipe the cutting wheel with an oil-soaked cotton swab or cloth before scoring. Reapply oil as needed during cutting. The diamond-alloy wheel delivers strong, smooth cutting across a wide thickness range. How to Replace the Cutting Head: 1. Remove the bit screwdriver. 2. Prepare a new cutting head. 3. Tighten the screws. 4. The cutting head is now ready for use. Important Notes: 1. Select the appropriate cutting head based on glass thickness. 2. Do not use on high-hardness materials like tempered glass, marble, or quartz. 3. Avoid repeating scores in the same spot to protect the cutting wheel. 4. Always work on a flat surface. Practice on scrap glass several times before starting your project.
