1. Ergonomic Design: The handle of the glass cutter is made of iron alloy with frosted particles. The sturdy pencil-type metal handle provides a non-slip grip, ensuring comfort and long-lasting durability. 2. Carbide Cutting Wheel: The diamond alloy cutting wheel delivers clean cuts and supports a cutting range of 2 to 20mm. 3. Alloy Percussion Head: The professional glass cutting head is made of metal, designed to score and break glass effectively. 4. Application: The glass cutter includes 3 spare cutting heads (2–6mm, 6–12mm, 12–20mm), suitable for glass thicknesses from 2mm to 20mm. Choose the appropriate blade based on the glass thickness and texture to optimize performance. 5. Compact: This manual glass cutter is lightweight, durable, and built for precision, making it easy to carry and ideal for household and professional use. Suitable for cutting glass, tiles, mirrors, and ceramics. Features: When pressure is applied to the cutting tip, oil is automatically released to lubricate the wheel during use. For beginners, it is recommended not to fill the handle with oil initially, as excess oil may leak during practice. Instead, use a cotton swab or small cloth soaked in oil to gently wipe the cutting wheel before use. Reapply oil as needed.
