MEGA ER Nuts

The MEGA ER Nut features built-in thrust ball bearings for high accuracy and clamping force. This ER collet nut is ideal for solid carbide drills and reamers. They have a slot-free outer diameter, which increases the rigidity of the ER nut itself.

The one-way clutch of the MEGA Wrench tightens the nut securely and easily with its ratchet function. We offer a variety of MEGA ER collet nut types with various outer diameters and lengths. Find the right one for your application below and get a quote today.
