Step Drills

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

Reamers

production of reamer tools

Our service of technical design and production of special tools guarantees the production of custom reamers for machining and finishing holes.


We produce special reamers in solid carbide, brazed and HSS, for internal moulds of any shape and contour. Our reamers can create finishes on through holes and dead holes, thanks to the specific construction of these tools with geometrics and helixes designed for finishes of various materials.


Available also with mechanical fixture inserts, C.R.M. reamers can be produced with customizable coatings, according to the needs of the client.


All the reaming tools are produced with highly technological machinery, following the procedures of the BS EN ISO 9001: 2008 CERTIFICATION.
