Mega ER Grip: High Quaility Tool Holders

Introducing the Mega ER Grip! The total precision of our collet, nut, and body shatter the common standard of ER collet chucks. BIG's Mega ER Grip is a high quality ER collet chuck that completely satisfies the 4 requirements for tool holders; clamping force, concentricity, rigidity, and balance for high spindle speeds.

Each part of the assembly puts together our high precision production technology and our design creativity for collets, clamping nuts and chuck bodies. When an inexpensive tool holder is selected based on a small cost saving, a waste in valuable time and money during production results in higher costs in the long term.

All collets are inspected twice in order to guarantee
the runout accuracy, which has a great influence on tool life.

By increasing the contact length of the internal taper of chuck bodies, the undesired overhang of the collet is reduced. This modification of the standard improves 3 of the most important requirements for the collet chuck (rigidity, runout accuracy, clamping force). (Conventional DIN collets can also be used.)

Sealed Collet Nut for Collant Through Tools

Nut for coolant Deliivery Around Cutter Shank Periphery

The unbalance of the drive keys in the steep taper and HSK tool shanks is reduced to a minimum by a pre-balancing operation. (BIG Coromant Capto tool shanks are also pre-balanced) The tool shanks also include tapped holes around the periphery so that precision balancing can be performed with balancing screws.
