V3 Files offers vide 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 diffrant name given to files vary according to their shapeand use.The most common name
are : Hand,Flat,Half Round,Round,Squre,Three Squre,Knife and double edge. e.g Flat files for
flat and concave surface,Round files for enlarging holes,Tringular files for filing corners and
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
Special Purpose file – Designed and used for specific application /materials.
Diamond Needle & Needle files – For precision filing application ain die making and Jewelry.
Rasps – Used wood by pattern/cabinet makers,leather and similar soft materials for rapid
Desired stroke length will determine the length of file. The V3 range include files from 4"(100
mm) 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 diffrant ways .Diffrant type of cut are choosen
depending on the work material, the desired rate of material removal and the desired finish.
The most common cuts are Single cut,Double cut,oberg cut,Diagonal cut,Milled cut and rasp
Single cut – Single cut files(mostly all saw Files are singlle cut) are used for sharpening & edging
application e.g Sharpening of saws where the piece is hard,point of contact is lessand finish is
Double Cut – Double Cut files need less effort for filing and also give good surface finish.
Bastard Cut – For stock removaland 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 centimetre along with the length of the File.The most common degrees of
cooarseness are bastard and second and smooth cut should be choosen.
For diagonal files, milled files the degree of coarseness is given in number of tooth tips per
• A new file should be used with light pressure in the begining,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.
