Strong centrifugal forces at high speeds can pull tool holders out of the machine spindle. Therefore, high tensile strength pullstud bolts are recommended to protect against this possibility. Our pull studs utilize H13 tool steel, which improves their tensile strength.
Most breakage occurs due to impurities in the material. Impurities eventually become cracks due to strong cutting and vibration forces. Other reasons for breakage are caused by dents created from ball clamp retention systems, compared to dual contact collet-type systems. Coolant alkaline levels will also contribute to shortened life span.
