The Hikoki GM13YW is a powerful concrete grinder designed for heavy-duty work on stone, ceramic tiles, and concrete surfaces. Driven by a 1900W motor, it allows you to fine-tune the grinding process using a six-step variable speed wheel that adjusts the no-load speed between 3800 and 8200 rpm. This flexibility ensures you can match the intensity to the specific hardness of your material. Its physical build focuses on versatility and user comfort, featuring a tool-less adjustable loop handle that lets you find the most ergonomic grip for different angles. The aluminum die-cast guard includes a folding segment, which is particularly useful when you need to work close to edges. To keep your workspace clean, the tool is equipped with a spring-mounted ring brush that integrates with Hikoki dust extractors. Measuring 475mm in length and weighing 3.6kg without the cable, the unit balances substantial power with manageable handling. It comes ready for immediate use with a diamond cup wheel, a 2-hole spanner, and a plastic carrying case for organized transport. The M14 spindle thread accommodates accessories up to 125mm in diameter, making it a reliable choice for professionals handling surface preparation and leveling.
