Mega Perfect Grip deploys a locking mechanism with a key grip that is said to prevent slip and pull-out of the tool, even during heavy cutting. The key grip engages in the chuck body's groove, while a spring maintains constant axial pre-load between the cutter and the internal groove. The key grip remains fixed so there is no slip.
The key grip accepts standard Weldon flat milling cutters, and no special grinding of the milling cutter is required. The grip grooves provide channels for high volume coolant to reach the cutter, which is required in milling HRSAs to dissipate heat and remove chips.
