The Grex P635 is designed as a fastener pinner with a motor that can go through some of the hardest woods. They boast that this product would be able to do up to 20,000 pounds of pull force.

The tool can be used with up to 1-3/8-inch fasteners as well as all of its other features such as being able to shoot 5/8" to 3/4" deep into material.

The tool's built design and speed is what allows it to shoot up to 16 times more fasteners per minute than a regular pinner. This is in comparison to the competition which is usually around 14 and 15 times per minute.

Aside from all of the speed and power this tool offers, it also contains other great tools such as latches and a trimmer for thin nails. It also has a built-in laser sight for pinpoint accuracy whether you are attempting to mark out exact locations of your nails or trying to get a feel for where your nail runs.
