قطاعة ثقب كربيد تنجستن 2-1/2 بوصة TcT للصفائح المعدنية صنع في الولايات المتحدة

Cut through 2" conduit like it was nothing, and the built-in flange kept it from walking on me. The carbide teeth still look sharp after a dozen holes in steel plate.

Wasn't sure a 3/8" shank bit would hold up in my old corded drill, but the carbide tips ate through a steel electrical panel like it was nothing. The built-in flange stopped it from walking across the surface, which saved me from drilling a second hole.
