High-Speed Balanceable End Mill Holders
CAT40 HSBalance™ End Mill Holder
CAT40 HSBalance™ End Mill Holder DIN
Balanceable End Mill Holders are available in CAT and BT taper styles.
Part numbers are identical to standard End Mill Holders part numbers
except that there is a “B” at the end. (Ex: C4006-0125B)
• 30 and 40 taper toolholders are prebalanced to G2.5 or better at 24,000 RPM
• 50 taper toolholders are prebalanced to G2.5 or better at 15,000 RPM
• Lyndex-Nikken uses a Patented Balancing Method which allows greater
compensation necessary for extremely high RPM applications.
• HSBalance™ toolholders come with a printout of actual balance condition
• HSBalance™ toolholders need to be used with balance-qualified pull studs
• A balancing machine is required to balance or re-balance toolholders
