Hard to start thread squarely- dulled before completed the job

Doesn't fit clean muzzle threads

I purchased this to chase a damaged muzzle thread. I tried it first on 3, clean, threaded, muzzles from different manufacturers. It would attempt to cut threads immediately. These barrels have clean, tight, threads that fit several muzzle devices. I don't trust this die to cut threads for a suppressor mount.
