Yes, the bi-metal construction is capable of cutting stainless steel, provided you use low speeds and adequate lubrication.
The set includes 22mm, 29mm, 35mm, 44mm, 51mm, and 64mm holesaws.
The two included mandrels cover different size ranges; use the 9.5mm for smaller diameter saws and the 13mm for larger ones.
Use a screwdriver or similar tool to pry the material plug through the side slots of the holesaw.
The case is designed for protection and portability, but it is not waterproof; avoid submerging it.
Reduce feed pressure and ensure the drill is held perfectly perpendicular to the surface.
Apply cutting oil or lubricant to the drill point and clear metal chips periodically.
Check the set screw on the mandrel and ensure it is tightened against the flat section of the pilot drill shaft.
To set up the holesaw, select the required size and screw it firmly onto the appropriate mandrel (9.5mm for smaller saws, 13mm for larger). Ensure the pilot drill is locked securely into the mandrel before operation. For maintenance, clean the saws after each use to remove wood shavings or metal chips trapped inside the cup. Store the components in the provided padded case to prevent moisture build-up and maintain the edge integrity of the teeth.
