Stepped drill bit set TiAlN HSS TiAlN 3 pcs

Stepped drill bit, HSS-TiAlN-coated, with TRICON shaft and laser scaling (DBGM)

The ideal tool for sheet metal working. This tool can be used to centre, spot drill, rebore and deburr sheet metal in one process. Indispensable tool, whether for the electrical trade, plumbing and heating systems, automotive workshops, mechanical engineering, switch cabinet manufacturing or container and instrument construction.
The robust tool is suitable for all common materials, such as non-ferrous metals, stainless steel sheeting, plastics, Plexiglas, various types of wood and all common steel sheeting up to a thickness of 4 mm. All stepped drill bits are labelled with a laser scale, enabling the hole diameter of each to be read off.


  • TiAlN coating

Maximum service life – no built-up edges, greater surface hardness, improved thermal stability, dry machining possible

  • TRICON shaft, positive-fit transmission of forces

No spinning in the chuck – optimal power transfer/no groove formation; no excessively deep clamping in the chuck – optimal elasticity; less effort required to open and close the drill chuck – protects drill chuck
