لقمة ثقب كربيد 7/8 بوصة للكهربائيين TcT تنغستن مع مثقاب قطع Hog®

Punched through 16 gauge steel panels way faster than my old bi-metal saws, and the carbide teeth still look sharp after a dozen holes. The flange stopped me from drilling too deep into the box, which saved me a couple of times.

Bought this for running conduit at my shop and the tungsten carbide tips chewed through 16 gauge steel plate without any chatter. The flange kept me from over-drilling into the panel behind it, which saved me on the first hole. No burrs either, so I didn't have to file anything down.

Punched through 7/8" holes in a steel junction box in seconds, and the edges came out clean with no burrs to file down. The tungsten carbide tip still feels sharp after a dozen holes, so I'm not babying it.
