L H Dottie Co CT28 Carbide Tipped Hole Cutter 1.75 in

Product Description

The L H Dottie Co CT28 is a carbide tipped hole cutter designed for cutting clean, precise holes in metal, sheet steel, electrical enclosures, and similar materials common in electrical and mechanical trade work. The carbide tipped cutting edge delivers durability through repeated cuts in hard materials where standard bi-metal cutters wear quickly. At 1-3/4 inches in cutting diameter, this cutter handles a range of conduit, fitting, and knockout applications. Electricians and HVAC technicians reach for this tool when installing conduit fittings, panel knockouts, or similar penetrations requiring a precise hole size.

The CT28 is suited for use in residential and light commercial electrical and mechanical installations. Typical applications include cutting holes in electrical panels, junction boxes, HVAC equipment cabinets, and metal framing members. The 1-3/4 inch diameter fits common trade applications where a clean hole is needed for conduit connectors, grommets, or fittings. The carbide tip construction holds up to repeated use on mild steel and similar sheet metal substrates without requiring frequent replacement.
