Conical boring tools

Conical and multi-step drills: conical drills have been built to drill flat materials of thickness till 2 mm and pipes till thickness 3 mm; with each tool a large range of holes can be produced on every kind of material without pre drilling. Multi step drills manufactured in HSS + TiN is used for making a large number of holes of different diameters in any material,ferrous or non ferrous. It is an improvement on the conical drills because the finish of the hole is exactly round and is very easy to use.
