Bonsicoky 4-Piece Countersink Chamfer Tool Set - HSS Deburring Tools For Metal & Wood (2-20mm)

Woodworkers and metalworkers, this 4-piece countersink set is exactly what you need for professional-looking holes every time! Made from high-speed steel with titanium coating, these tools handle deburring and chamfering on wood, PVC, aluminum, and insulation boards with ease. You get four sizes covering holes from 2mm to 20mm: 2-5mm, 5-10mm, 10-15mm, and 15-20mm - so you're prepared for any project. The 90-degree angle creates perfect, smooth bevels while the through-slot design prevents chip clogging. These work best with a bench drill at low speeds (add water or cutting oil for cooling), giving you clean, professional results that eliminate sharp edges and prepare holes for screws. The round handles provide comfortable grip, and the quality construction ensures these tools will last through countless projects. Whether you're working on furniture, metal fabrication, or DIY home improvements, having the right chamfering tools makes all the difference in achieving that factory-finished look. This complete set covers all your deburring needs in one affordable package.
