Gripper jaws feature serrations on the inner and outer gripping surfaces. This particular design offers a super strong grip on end grain and in green timber. The depth of the jaw adds to the gripping power. The SK80 Gripper Jaws Type H are ideal for smaller hollow form and similar pieces. Although, as with all the Axminster chuck jaws, versatility comes as standard. The external grip is 53mm, the internal 40mm. These diameters are when the jaws are a true circle. However, the chuck allows a wide range of movement to accommodate any deviation. If necessary, it can grip internally 34mm to 66mm and externally 47mm to 83mm. Of course at more extreme diameters, the jaws are no longer a true circle.
The SK80 Gripper Jaws Type H are also suitable for the SK100 and SK114 chucks.
N.B. The finish may be either silver or black due to changes in legislation regarding passive zinc plating.
