Clamps with grip jaw
Clamps with pin grip jaws
These models are equipped with n hard steel pins (n = 1...3 pcs), which increases the friction between the workpiece and the jaw.
Clamps with code ending on Gn (e.g. DK2-VT-G2) contain n pieces of grip pins in both jaws. In clamps with code xK2-VT-RGn one jaw is serrated and hardened. Other jaw combinations are available upon request.
Clamp DK2-VT-RG3 (D-size with 3 grip pins in one jaw) is shown in the photo below.
Clamps with tungsten carbide coating
This type of clamps posses two jaws with hard tungsten carbide coating.
When no clamping marks are allowed in the workpiece but still high friction is needed, these clamps are an excellent choise.
Or when thin-walled workpieces are being machined, these jaws create required holding force with less clampforce, preventing distorsions of the workpiece while clamping.
