No mention of country of origin, so I think it's safe to assume these are most likely Taiwanese or Chinese. That alone doesn't make them of poor quality, but certainly impacts the price.
Professional Tool Products' website makes no mention of their own manufacturing, they are a sourcing / design business. They do claim to source some items in the US as well as in Taiwan and China. So if this is an item that Cornwell is purchasing from them, I'd venture that it's similar / the same was what you could buy from another brand for even less money. This is important because it starts to impact the achievable quality of the product at a given price. I have a little bit of manufacturing experience, so my take on this is as follows:
Tool truck tools are generally expensive because there is a margin paid to the driver / franchisee for sales and service (30-35% seems to be industry standard) as well as a margin to the brand (Snap On, Mac, Matco, Cornwell, etc) to cover R&D, warranty, logistics costs, etc.
- For a $60 tool, the truck driver pays somewhere around $40.
- Then the brand would have a margin - I'm unsure what amount that would be for a tool they're sourcing rather than manufacturing, but it'd need to be at least 40% to account for warranty replacements, logistics costs, etc. So that puts their cost for the tool around $24.
- Then the sourcing agent, possibly Professional Tool Products in this case, needs to make a margin - this could be lower depending on how much support / warranty they offer and what level of logistics support they're providing. But even at 25% your $60 tool is realistically around $17-18.
Likely, these tools cost even less and the margins are greater everywhere. I think it's unlikely that these tools are any better than the similar sets you can buy from Tekton, Capri, and other TW sourced brands for 40% less money. If I were trying to save a buck, I'd probably buy from Tekton or Capri and get an equivalent tool.
