مثقاب ثقب كربيد 1-3/4 بوصة، قاطع ثقب كهربائي، لقمة فورستنر من TcT تنجستن، عدة

Bought this for a subpanel install and the 1-3/4" size was dead on for 1-1/4" conduit connectors. The tungsten carbide teeth sliced through 16 gauge steel like it was cardboard, way faster than the bi-metal saw I was using before. Chuck it in a 3/8" drill and it just goes.

Cut three 1-1/4" conduit holes in my panel with zero chatter, and the 3/8" shank fit my older corded drill fine. The chips clear fast too, no clogging like the cheaper bi-metal ones I've used.

The carbide tips chewed through 1-1/4" conduit without any chatter, way faster than the bi-metal saws I used before. The 3/8" shank dropped straight into my cordless drill with no wobble at all. Holes came out clean enough that I barely needed to deburr.
