MEGA ER Collets

For End Mills

MEGA ER collets for end mills are specifically designed to fit common end mill diameters. Nominal sizes of collets for the most popular end mill shanks reduces the unsupported overhang of the collet when clamped into the chuck body. This increases the rigidity of the tool assembly in the horizontal direction which is very important to end milling operations. Available in both metric and inch sizes.
