V3 Files offers wide range of diverse application. Hand Files are classified into the following categories: Engineering Files, Saws Sharpening file, Needle Files, Milled Files, Rasps Files & Special Files. V3 Files are available in range of application in wood working, automobile, engineering, aviation, heavy Industry,garages,steel industry etc.

Description of V3 Files : It is the shape and size of the work piece, the material from which it is made and desired finish that determine the Choice of File. V3 range covers all these areas meeting the requirement of most National & International Standards with ample margin.

File type/ Shape

The different name given to files vary according to their shape and use.The most common name are : Hand,Flat,Half Round,Round, Square, Three Square, Knife and double edge. e.g Flat files for flat and concave surface,Round files for enlarging holes,Triangular files for filing corners and angles, etc.

Machinist File – For stock removal and surface finish requirements on machined components.

Saws Files – For sharpening wood working Saws and similer thin edges such as chaff cutter blade,matches.

Special Purpose file – Designed and used for specific application /materials.

Diamond Needle & Needle files – For precision filing application and die making and Jewelry.

Rasps – Used wood by pattern/cabinet makers,leather and similar soft materials for rapid stock removal.

Length:  Desired stroke length will determine the length of file. The V3 range include files from 4"(100mm) in length to16"(400 mm) depending on Type.The most suitable file length depends entirely on work to be done or desired stroke length.The length of the file is always is given excluding the tang with exception of needle file,where the total length includes the tang.

Tooth Type & Cut

The toothing of a file can vary in many different ways .different type of cut are chosen depending on the work material, the desired rate of material removal and the desired finish. The most common cuts are Single cut, Double cut, Diagonal cut, Milled cut and rasp cut.

Single cut – Single cut files(mostly all saw Files are single cut) are used for sharpening & edging application e.g Sharpening of saws where the piece is hard,point of contact is less and finish is required.

Double Cut – Double Cut files need less effort for filing and also give good surface finish.

Bastard Cut – For stock removal and coarse finish.

Second Cut – For moderate stock removal and medium to coarse finish.

Smooth Cut – For smooth surface finish.

Rasp Cut – Special Cut formation for rapid stock removal from surface and softer materials like wood or leather.

For all cut Engineering needle and sharpening files the coarseness of cut is given in Number of work teeth per centimeter along with the length of the File.The most common degrees of coarseness are bastard and second and smooth cut should be choose.  For diagonal files, milled files the degree of coarseness is given in number of tooth tips per cm2.

Technical Guide

• A new file should be used with light pressure in the beginning,preferably on a surface which has
• been filed earlier.
• In case of clogging of file teeth,clean the teeth with a soft wire bush
• Use the files for cutting in the forward stroke only.
• Filing jobs should be held rigidly.
