Removing putty from windows is almost never a fun task — you run the risk of breaking the window if you push the wrong way, and you can scorch the wood if you try applying heat. I usually end up just using a putty knife and hoping for the best, but this Prazi Putty Chaser looks like it could take a lot of the work out of the job.
The tool works with a 1/4” or 3/8” drill that can produce 2,000-3,000 RPM. The tool’s carbide cutter will take off that old putty with ease, without leaving splinters in the wood. No need to even remove the window — just keep it in place and do the job.
This made-in-the-USA timesaver’ll run you about $18.
