Ignoring the thickness which we all concur it must be a typo, the goal of a machete is to make fast cuts with long swings on (usually) soft material (think jungle situation). They are usually thin long blades.
I personally think that your chopper is way too thick for regular machete use. For hardwood it will probably do great, but for trail clearing is going to be tiring to swing for a long time.
