Depending on your requirements, a single drill bit can be used to drill holes in sizes of 4 to 12 mm, 4 to 20 mm or 4 to 32 mm.

The ideal tool for sheet-metal working in the electrical and automotive industries, sanitary engineering and heating technology, as well as in mechanical engineering.

Ideally suited to all common industrial metals, thermoplastics and thermoset plastics up to a thickness of 3 mm.

Even the thinnest of sheets can be drilled without causing any deformation. The special cutting geometry enables drilling and deburring without the need for pre-drilling.

The special TiN coating creates a surface hardness that is up to 600% higher, thereby increasing the service life of the tools noticeably. Supplied in a sheet-metal box.
