Toolholders a critical connector
Toolholders are the critical connection between a cutting tool and a machine tool spindle. Toolholder performance dictates productive output, surface finish of a part and the life of a cutter. With the right toolholder for the application at hand, a shop maximizes benefits from high-performance cutting tools and machine tools.

Different toolholder types provide different levels of performance. Depending on the machining application, some performance factors are more important than others. For precise work, a low total indicator runout may be most important. When multiple setups are involved, quick-change capability is essential to maximize productivity. In heavy-cutting situations, tool retention force might be emphasized. And in most operations, the cost of the tooling system itself is a significant factor.
When it comes to the various toolholders and their qualities, ER collets are known for gripping strength and accuracy. Collets in the ER system, which was introduced in the early 1970s by Rego-Fix Tool Corp., Whitestown, Indiana, and later standardized as DIN 6499, supply a wide clamping range and high accuracy over an extended selection of operations.
