Senkerbit Countersink & Deburring Drill Key benefits Durable cutting performance: made from high-speed steel with high hardness and rust-resistant finish for long-lasting use. Clean, consistent edges: designed for smooth chip processing to produce clean chamfers and reliably remove burrs. Reduced clogging and longer life: chamfer groove promotes chip and debris discharge so the cutter stays sharper longer. Versatile function: combines chamfering, deburring and cone/countersink processing in one tool. Main features Brand: Senkerbit Material: high-speed steel (high hardness, rust-resistant) Type: solid countersink / deburring drill for chamfering and cone hole processing Performance: smooth chip evacuation, stable cutting, resistant to dulling Compatible materials Plastic, PVC boards Aluminum and aluminum plates Copper Stainless steel Insulation panels What it does Chamfers circular openings and creates precise conical holes for fastener seating. Removes burrs and sharp edges after drilling or cutting. Provides smooth chip flow during cutting thanks to the integrated groove. Practical use scenarios Mechanical assembly: chamfer bolt holes in aluminum panels so screws and rivets sit flush and parts assemble cleanly. Pipe and HVAC work: deburr and chamfer PVC and insulation panels for leak-free seals and neat joints. Metal fabrication: finish edges and create countersinks in stainless steel or copper components before welding or final assembly. Why customers choose it Straightforward, reliable performance for shop and field work. Multi-function capability reduces tool changes for chamfering, deburring and countersinking tasks. Built to resist corrosion and maintain cutting quality under repeated use.
