WEDGE / PISTON : It is made of Nickel Chrome alloy steel, case hardened and precision ground hardness 56-60 HRC. It is designed to bear high forces.

TECHNICAL FEATURES :
Steel Body with all wearing surfaces are hardened and ground.
Complete system of internal lubrication with grease.
Repetitive Gripping Accuracy is with in 0.050mm in Hard Jaws and 0.020mm in Soft Jaws.
Safety system is provided in unlikely cases of accidental breakage.
Serrations for mounting jaws are precision ground and are available in 1/16”x90° and 1.5mm x 60° pitch.
Maximum recommended speeds are based on the speed at which 20% of the static gripping force is lost due to centrifugal force.

Files can be select according to the shape & size of the work piece , the material it is made of will have to be considered while selecting the right file.

File Type :
According to the filing application , files are classified into the following categories.
i. MACHINIST Files : - for Stock removal & surface finish requirement on machined components.
ii. SAW Files :- for sharpening wood working saws, cutter blades, machetes & similar thin edges.
iii. RASP Files :- Used by pattern / cabinet makers on wood , leather & similar soft materials.
iv. MILL files :- Used for stock removal on soft metals.
v. SPECIAL FILES :- used for specific application / materials

LENGTH :
Files is measured exclusively of the tang from point to heel.
