Extendable long-reach neck: Pull the tab to lengthen the neck up to 2 inches, giving access to recessed or awkward deburring locations and conforming to irregular shapes. Complete 16-blade kit: Comes with 15 extra blades plus the installed cutter for a total of 16 blades in three sizes to handle a range of jobs: - 6 × BS1010 blades — 0.57" length, made from 64HRC steel; ideal for steel, aluminum and plastic. - 5 × BS1018 blades — 67 HRC for tackling tougher steel and harder materials. - 5 × BK3010 small blades — designed to deburr holes down to 1.5mm diameter. Convenient onboard storage: Built into the tool is blade storage so spares are kept at hand during work, reducing interruptions and speeding up tasks. Works on many materials and tasks: Use it to clean up edges on steel, aluminum, copper, pipes, automotive parts, gears and other freshly cut metal surfaces. It also trims and deburrs 3D printed plastic parts — a handy plumbing accessory for plumbers, and a useful tool for industrial workers, machinists and DIYers. High-speed steel cutting performance: Blades are made from tempered high-speed steel (HSS) for improved toughness, wear resistance and longer life — HSS typically lasts 80% longer than standard steel, which is why these blades are specified for durability and consistent cutting.
