Product Description
Our ER spring collet system have an improvement, and is a big one! The ER+is a new concept available for the traditional and well known spring collet system. This new design of the nut and the holder reduce the external diameter of the holder while increasing the clamping force over the collet and giving extra rigidity to the whole system. This design is less invasive than the traditional system, allowing machining areas where traditional ER holder just cant get, while giving the cutting tool a longer life.
The nut have an external thread instead of the internal thread than traditional ER nuts have. Have in mind that these nuts and holders are not interchangeable, ER+nuts have to be used with ER+holders, but you can use your traditional collets with no issues at all in any of both clamping systems.
Our Metaltech Tools nuts and collets are made of high stength steel and are guarantedd to over perform your expectations.
Please remember to assembly the collet into the clamping nut before inserting the tool or put the collet into the holder, also dont forget to visit our collets and wrenches station. We carry a wide range of collets as well as all the right tools to clamp them tight!
