7/8-Inch Carbide Hole Cutter for 1/2-Inch Conduit

This carbide hole cutter is designed for electricians and metalworkers who need clean, accurate holes in sheet metal. It cuts stainless steel, mild steel, iron, copper and brass up to 3/16-Inch thick. The 7/8-Inch diameter matches standard 1/2-Inch conduit requirements.

Integrated Flange and Split Point Pilot Bit

An integrated flange stops the tool from drilling past the workpiece surface, protecting both the material and the operator. The split point pilot bit prevents walking at the start of the cut, keeping the hole centred without a centre punch. Replacement pilot bit 31874 is available separately.

Check Material Thickness and Chuck Compatibility

Verify that your sheet metal does not exceed the 3/16-Inch maximum cutting depth before use. Ensure your drill chuck accepts the cutter shank and that the pilot bit is sharp or replaced with part 31874 for best results. This tool is not suited for materials thicker than specified or for non-metallic substrates.
