ER Wrenches for Machinist Shops
The ER collet, often considered to be the most accurate type of collet made, was invented and patented in 1972-73 by Swiss toolmaker, Fritz Weber. It has come to be the most popularly used clamping system for cutting tools worldwide. ER collets are available in eight standard sizes (ex: ER11, ER16, ER20, etc). The number refers to the size of the collet opening, expressed in millimeters.
An appropriate collet wrench is required for each differently sized collet nut being used in your shop. The ER collet wrench selection we offer here at DZ Sales includes the most widely used standard sizes. These ER wrenches for machine shop use are manufactured from high quality alloy steel and capable of providing high torque leverage on collet nuts without bending.
