A set of circular punches designed for holes in S235 steel sheet. It contains seven pairs of punches and dies for sizes M16 to M63; the actual hole diameters are 16.2, 20.4, 25.4, 32.5, 40.5, 50.5 and 63.5 mm. The punch splits the slug into three parts, reducing the risk of it jamming in the die. The plastic case also includes four draw bolts with ball bearings: two 9.5×50 mm, one 19×55 mm and one 19×75 mm, a 10 mm HSS pilot drill bit and lubricating paste.
