Key benefit: Quickly damaged bolts and reseat nuts without replacing expensive or hardtofind hardware, reducing downtime and maintenance costs. Easy to operate: Use the lowest speed setting on your drill and apply gentle pressure to remove burrs. Simple, efficient, and timesaving. Wide material compatibility: strength and hardness performance. Suitable for stainless steel, hardened steel, soft steel, lowcarbon steel, copper, brass, aluminum, fiberglass, wood, and plastic, whether threaded or nonthreaded. Material and build: Chamfering tool made from strength, hardness speed steel for durability and long service life. Use scenarios: Automotive or machinery maintenance: quickly damaged bolts and tighten nuts in place without replacing hardware. Metal fabrication and assembly: deburr and chamfer ends on stainless steel, aluminum, or copper parts to ensure smooth fit and prevent injury. Wood, plastic, or composite work: bevel edges to improve assembly ease and finish quality on nonmetal parts. Notes: Designed to deliver reliable performance across a range of common materials and applications, preserving parts and simplifying maintenance tasks.
