مثقاب ثقب كربيد 1-3/8 بوصة منشار ثقب TcT تنجستن لقطع الصفائح المعدنية

Bought this to punch a hole through 16-gauge steel for a project enclosure and it went through in seconds. The tungsten carbide teeth left a clean, burr-free edge, so I barely had to file anything. Way better than the bi-metal saw I used to fight with.

Cut through my truck's rusty fender panel cleanly with no burrs at all, which I honestly wasn't expecting from a hole saw. The carbide teeth stayed sharp through about a dozen holes. The 3" overall length gave me enough reach to get past the inner brace too.

Punched through 16 gauge sheet metal like it was cardboard, and the tungsten carbide tips still look brand new after a dozen holes. The 3" overall length gave me enough reach to clear the flange on my duct work. Zero burrs on the backside, which saved me a ton of filing.
