VEVOR 15 Ton Hydraulic Knockout Punch Kit, 1/2" to 4" Conduit Hole Cutter Set, KO Tool Kits W/Puncher 10 Piece, Metal Sheet Driver Tools, for Aluminum, Brass, Stainless Steel, Fiberglass and Plastic

Cuts smooth holes with little effort

Excellent

Cuts clean

This kit is well worth the money. Heavy duty cutting dies up to 4”. The 31/2” and 4” knockout dies alone will cost you about a $100 if bought separately. Kit arrived in a small packing crate, each die individually wrapped in plastic/foam. A lot easier to use than a hole saw and definitely much safer. Kit is heavy as weighs about 60lbs.

Funktioniert top

C'est du lourd ! La mallette pèse son poids. Parfait pour les trous au dessus de 20 mm et jusqu'à 140 mm. Respecter les épaisseurs de tôles. Je ne sais pas si ce produit est capable de perforer les épaisseurs annoncées.

Muy satisfecho con mi compra

This knockout punch kit is literally comparable with expensive brands in the market. I tried a few 4 and 3 inch holes on a pretty thick metal sheet and it worked tremendously awesome!!!!! I highly recommend it for anyone who has doubts of how well this kit works!
