Morse CTS56 Carbide Hole Cutter

The Morse CTS56 is a carbide-tipped hole cutter with a 3-1/2 inch (89mm) diameter designed for precision cutting in sheet metal. It targets electricians and maintenance professionals who need clean holes in control panels and electrical boxes. The ground tooth profile delivers fast, accurate cuts while the step center pilot drill reduces breakthrough impact. A shouldered body prevents pass-through damage to internal components at shallow depths.

Suited For Sheet Metal Panel Work

This cutter suits tradespeople drilling precise holes in thin metal enclosures where protecting internal wiring is critical. The ejector spring simplifies slug removal for repetitive tasks. It is not for buyers who need to cut thick plate steel, wood, plastic or other non-metallic materials. Builders requiring larger diameters or different arbor configurations should look at other options.

89mm Diameter Defines The Application

The 89mm cutting diameter is the single specification that determines if this tool matches the required hole size. Replacement parts are available using pilot drill 166010 and ejector spring 166027. One cutter is supplied per box.

Questions about this item

How can I verify the CTS56 is cutting cleanly after I install it?

Check that the ground tooth profile produces smooth edges without burrs, the step center pilot drill keeps the cut centred, and the ejector spring pushes the slug free after each hole.

What comes in the box and which replacement parts must be ordered separately?

One CTS56 carbide-tipped hole cutter is included; the CTSP 166010 pilot drill and CTSS 166027 ejector spring are available as separate replacement parts.

Which Morse cutter should I choose for a 3-1/2 inch hole in sheet metal?

The CTS56 with 89 mm diameter is the model specified for that exact size and material.
