Cheater bars are appropriately named, especially when it comes to tightening tool holders. We see the common pipes that are often added to the end of wrenches to achieve more torque in customers’ shops all the time. And while these makeshift wrenches may make tightening or loosening holders easier, the damage they can cause is often overlooked.
BIG DAISHOWA’s MEGA NEW BABY CHUCK has been delivering extreme precision for more than 20 years and is now available with up to ø1″ clamping for drills, reamers and finishing end mills with .00004″ runout accuracy.
Cleanliness is key to achieving good runout control when assembling tool holders. Small particles or oil in a tool holder can cause large runout of the cutting tool, deceasing tool life and performance.
