Machinists, metalworkers, and anyone dealing with burrs - this SHAVIV Mango II deburring set is an absolute game-changer for cleaning up edges and holes! The set includes the Mango II handle, B blade holder, and two styles of B blades (B10 and B20), giving you everything needed for tackling different deburring tasks. SHAVIV has been the original hand deburring tool since the 1960s, and the quality shows - these tools are built to last through years of professional use. The 'Workhorse' set is perfect for long reach work on holes, slots, and edges, making it ideal for straight edge applications and hole edge cleaning. The ergonomic handle feels comfortable in your hand during extended use, and the blade holder securely locks blades in place while allowing quick changes when needed. We've used this on various materials including metal, plastics, and wood - it removes burrs cleanly without damaging the workpiece. The blade design allows you to reach into tight spaces and complex geometries that machines can't handle, increasing your productivity without downtime. Whether you're in manufacturing, prototyping, or hobbyist machining, having quality deburring tools makes the difference between a professional finish and a rough one. The blades are sharp and durable, maintaining their edge through repeated use. Seriously, if you're tired of imperfect edges or spending too much time on finishing work, this SHAVIV set delivers precision and efficiency that'll make you wonder how you managed without proper deburring tools!
