How do I choose a benchtop jointer?
Look for a benchtop jointer with a dust-collection port that you can attach to your system or shop vac. Generally speaking, these ports should accept 4-inch or 2½-inch hoses. These are the most common sizes and will allow your vacuum or dust collection system to remove a large volume of chips at a time and avoid clogs.Dec 2, 2020
