Corradi Platinum Three Square Needle File 180mm

These quality 3-Square needle files from Corradi Italy are specifically designed for use with Platinum thanks to the CORINOX® coating.  They have a surface hardness of 1200 HV (70-72 HRc), therefore a higher wear resistance and longer service life. That allows filing of hardened and tempered steel up to 60 HRc, hard-to-file materials like heat resistant steel, exotic alloys and reinforced plastics.

They do not clog, allowing an easy work on plastics, rubber or wood. They have a surface corrosion-free layer, which allows filing of stainless steel leaving no corrosive residue on the workpiece. They allow filing of hard materials which normally would require diamond files, with lower cost and higher stock removal. Corradi platinum files are used for manufacturing of equipment for food, chemical, navy industries and nuclear power plants.

Three square files are also called triangular files, the sides of this file gradually taper to a point. All three sides are double cut. When used along a corner of the file, it will create a V-groove with a 60 ̊ angle. Useful for filing/refining seats in prongs.

Manufactured using a special alloy steel, made for CORRADI, under the highest quality standards. They have strict size tolerances, uniform cut and hardness on the whole tool. They are used by mold makers, goldsmiths and musical instruments manufacturers for working on small surfaces and finishing.

Thanks to their round shank, they can be used also without handle. Knurling avoid any slippings.
