The most widely used clamping system for straight shank diamond tools is the ER Collet.
The series number is the opening diameter of the tapered receptacle, in millimeters.
Available in 4 different sizes:
You can choose Er collet with a diameter from 3 mm up to 20 mm.
This is the diameter of the diamond tool that you can use (tool shank diameter)
These ER collets are made of hardened steel and are ideal for many machining applications including boring, milling, reaming, tapping and grinding.ù
You can choose also the treatment standard or darkside.
The darkside treatment is an extra corrosion treatment that makes the tool life even longer.
