قواطع ثقب كربيد 2-1/4 بوصة منشار ثقب TcT تنجستن لقطع الصفائح المعدنية Drill Hog

Cut through 16 gauge steel like it was butter, and the built-in flange kept it from walking on me. The 3/8" shank fit my corded drill fine. Only gripe is it throws chips everywhere, but that's hole saws for you.

Bought this to punch a 2-1/4" hole through some 16 gauge sheet metal and it sliced through in seconds without chattering. The tungsten carbide teeth still look sharp after about a dozen holes. Fits my 3/8" drill chuck fine.

Punched through 14 gauge sheet metal cleanly with no chatter, and the built-in flange kept it from walking on the pilot hole. The 3/8" shank fit my drill fine. Cuts way faster than the bi-metal saws I used before.
