C.R.M. creates solid carbide, brazed and HSS step drills, for internal moulds of any shape and contour. These are special tools capable of extending a hole which is already present, predisposing it for the finishing or for reaming during mechanical production.
Our technicians specializing in tool manufacturing can accommodate the number of cutting edges and structure of the drills, depending on the material to be worked and the various mouldings to be made during the production phase.
Furthermore, they can be coated specifically for the installation on different machine tools.
At our headquarters in Ponte San Pietro, projects for special step drills products with indexable inserts are also available.
All the step drills are produced with highly technological machines, following the procedures of the BS EN ISO 9001: 2008 CERTIFICATION
