A serrated gripper uses hardened teeth to bite mechanically into the workpiece surface, providing both clamping pressure and positive grip. This gives far greater resistance to movement during aggressive roughing cuts compared to smooth jaws, which rely on friction alone.

SerraGrips are made from premium A2 tool steel and hardened to 55-58HRC, giving them excellent durability and wear resistance under repeated clamping loads.

Because serrated gripper jaws clamp on a small amount of stock in OP1, the low clamping depth required further minimises the amount of material needing to be removed in OP2, lessening material wastage and optimising cycle time efficiency.

As a general rule, you should expose enough stock above the gripper face to allow for your roughing passes while keeping the clamping height as low as possible to reduce material waste. Pay close attention to the corner radius of the material you are trying to clamp. Some aluminium extrusions and hot rolled steel can have larger corner radiuses that mean more grip height is needed in the jaws. SerraGrip jaw sets have a 2mm grip height by default which we found works well on most types of material.
