Hi-Q balancing system

Ready to accept Hi-Q balancing rings which allow for the offset of the imbalance introduced by the cutting tool up to 80,000 rpm depending on the balancing rings used. All colletholders with the additional type information “H” in the article name are designed for balancing rings.

Hi-Q / ER clamping nut included in delivery

Guarantees highest clamping force and best balancing.

Vibration dampening

Our holders offer good vibration dampening to sustain a high surface finish and can help prevent chatter.

Key advantages of CAT+ REGO PLUS dual contact colletholders

The BIG PLUS SYSTEM – licensed by BIG Daishowa – is manufactured at REGO-FIX in Switzerland under license according to BIG PLUS specifications. CAT+ colletholder show a higher colletholder stiffness due to taper (AT1) and face contact. Improved machining accuracy and better surface finish are two more benefits of CAT+ holders. The form A+AD is the standard configuration.
