Slot punches are a great idea if you have an ongoing number of ID cards in use. They eliminate the need to use card holders, as you simply put your card holder clip or lanyard straight through the slot in the card.
The 3 in 1 versatile punch is great value as it covers all the options. It is uniquely designed to have 3 separate punching functions. A 1/4″ (6.35mm) hole punch (great for the snap swivel or karabiner clip), a 14mm x 3mm slot punch (perfect for the alligator clip) & a 3.5mm radius corner cutter. It also comes with an adjustable paper guide.
This desktop slot puncher has a heavy duty frame. It punches a slot 14mm wide and 3mm high. It will punch up to .76mm (standard ID/credit card thickness). It’s very easy to use as it works just like a stapler!
