Cutting fluids can be used with twist drills but are generally not needed for thinner gauge sheet metal.
How to twist thin sheet metal.
Tin snips are primarily used for cutting thin sheet metal like tin aluminum brass and thin gauge stainless steel.
I keep blowing through my thin sheet.
You may want to have a bottle on hand for when drilling through thicker sheets or steel.
I don t think there is a sheet metal feature that will do that.
Hardness testing on thin sheets and coated metal sheets are performed to determine the surface hardness of the metal and coating.
The hardness test is performed primarily for quality control in rolling and coating processes.
I guess the problem with that method is that would not account for the part shortening due to the twist.
Because these coatings are usually a few micrometers to a few tens of micrometers in size hardness test methods with.
But you can just add the twist at the end and suppress it for the flat pattern.
The average hack requires at least one angled metal part and the best tool to make one is still the good ol press brake.
