These high precision broaches are designed specifically for clearing blockages in your valuable spray tips.
When reversing the tip or blowing through with an air line will not shift the debris, you need to use one of these.
Have you ever damaged a tip by poking a piece of wire down it? Well, you were on the right track, but unlike your wire brush, the blade of the broach is shaped just like your spray tip so it helps to prevent damage occurring during the unblocking process.
These really do save tips!
