Circular Saw Metal

A hand held electric saw designed specifically for cutting sheet metal. Used by metal roofers and cladders.

Cermet Tipped Blade

A type of saw blade that looks like a TCT blade but it has ceramic and metal qualities. Used in saws designed for cutting sheet steel. That is metal roof sheeting.

High Speed steel

Steel used to make metal drill bits,saw blade etc. Shortened to HSS.

Swarf

The fine metal shavings and dust caused by drilling or sawing steel. The leftovers of the operation.

It is quite possible to cut sheet metal with a power saw using an abrasive disc or with a HSS blade, sometimes called a screech er because of the piercing noise it makes. Both have significant drawbacks for roof cladding. One being that they generate lots of heat that burns the coating on the cladding close to the cut, and the other being that they spread swarf over surfaces that should remain clean and free of it. (Swarf that is left on a metal roof will rust very quickly and that rust can and does spread to the coated steel roofing.

These saws are designed for sheet metal roofers and the bulky metal guard is a container that collects the swarf.

It Is claimed by the manufacturers that these cermet tipped blades cut down the amount of heat generated in the cutting process.
