Knockout punches Greenlee Slug Buster S1
Slug-Buster. Round. Ball-bearing. Splits the ”slug” in two pieces, which means it does not catch around the draw stud or in the die. Predrilling of the hole for the draw stud is done only 0.1 mm larger than the draw stud. This gives excellent centring. Intended for steel and aluminium sheet, glass fibre and plastic.
Sets in box excl. draw stud.
