What type of saw does not require a pre-drilled hole to begin cutting?

A Kett saw is specifically designed for cutting metal or other materials without needing a pre-drilled hole, which makes it particularly useful for applications requiring clean, precise cuts in thin materials. The unique design of a Kett saw allows the blade to plunge directly into the material, enabling the user to start cutting from the surface directly, adding to its versatility in metal structural repair.

In contrast, other options may require a starting hole for effective cutting. For instance, a band saw typically has a continuous closed blade, which necessitates an entry point into the material to begin the cut. A circular saw, while effective for straight cuts, generally requires an edge or hole to get started as well. Similarly, although a reciprocating saw is capable of aggressive cutting, it often needs a hole or cut-line to initiate the sawing process effectively. Therefore, the Kett saw stands out for its ability to eliminate the need for a pre-drilled hole.
