MEGA ER GRIP Collet Chuck has a high-precision collet, nut, and body; outperforming standard ER systems, improving machining capability and reducing cost.
Strong centrifugal forces can pull tool holders out of the machine spindle. Our pull stud bolts utilize H13 tool steel, which improves their tensile strength.
ER nuts are basic nuts with surface treatment for friction reduction. They have slots on the outside diameter and use a spanner wrench for nut tightening.
Secure your machinery with the reliability and strength of BIG DAISHOWA pull stud bolts, engineered to thrive in the most demanding operational environments.
