Deburring Blade (Concave) is an innovative deburring tool that offers increased task efficiency and, depending on your usual tool, reduced risk of injury. Featuring a concave design with an additional straight, beveled edge, this blade easily removes burrs and other defects from raw edges and produces a smooth finish on a range of materials from sheet metal to injection-moulded plastics. The blade is made from 100% zirconium oxide, a type of ceramic that is exponentially harder than steel, offering a more durable alternative to traditional deburring tools. The 10484 needs to be replaced less often than its metal counterparts, as it lasts up to 11-times longer, allowing for excellent long-term use.
