Ideal for cutting holes in ceilings and walls, drilling through wood, plastic, aluminium or plasterboard. The hole saws are made from HSS steel, a highly resistant material that offers great cutting capacity without deteriorating and allows very precise cuts to be made. The toothed section is micro-welded to the body and has a special heat treatment. The tooth pattern is variable (4/6), with a positive cutting angle. The teeth have a hardness of HRC63, helping to achieve fast, precise and easy cuts. The base of the hole saws is reinforced to reduce the vibrations produced during cutting. The body is made from highly flexible alloy steel and has side slots to help expel dust. The arbors, designed to help guide the hole saw during the cutting process, are made from alloy steel, a highly elastic material. The arbor guide is made from HSS steel. The quality of the materials used to make them and their careful design make them perfect tools for professional work. They offer a very long service life and great cutting precision.
