The Alpha SM3SDTP-B ThunderMAX Step Drill TUFFBOX Set is a 3 piece metric spiral flute set designed to drill and deburr in one smooth process. Covering 4 to 12mm, 4 to 20mm and 6 to 30mm, it handles a wide range of hole sizes in sheet materials.
Each bit features a self starting split point that removes the need for a pilot hole. The tempered black finish improves lubricant retention, chip flow and heat dissipation while providing corrosion resistance. Supplied in a durable TUFFBOX Pro case, this set is built for tough job site conditions and suits both power drills and impact drivers.
