Stepped drill bit, HSS Ti
AlN-coated, with TRICON shank 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.

Advantages:

• Ti
  AlN coating

Maximum service life - no built-up edges, higher surface hardness, higher heat stability, dry machining possible

• TRICON shank for mechanical-interlock power transmission

No movement in the drill chuck - optimal power transmission/no groove formation; excessively deep clamping in drill chuck is avoided - optimal elasticity; low energy expenditure when opening and closing the drill chuck - protects your drill chuck
