ER spring collet
This is a spring collet according to the German DIN 6499 standard. The runout accuracy is ±15 microns to ±20 microns, but it is inexpensive.
This is an ER collet that conforms to the DIN 6499 standard. The accuracy is at a standard level. While Japanese-made ER spring collets have runout accuracy of ±0.003 mm to ±0.005 mm, the Fasttech ER spring collets have a runout accuracy of ±0.015 mm to ±0.020 mm. Even so, they are more precise than drill chucks and can securely hold drills. This is a user-friendly ER spring collet that prioritizes low cost over high standards of runout accuracy.

Distributors
Our company specializes in "workholding tools" that maximize the operating rate of machine tools. In particular, we are focusing on the rapidly increasing demand for 5-axis machining and multi-surface machining, offering products such as "self-centering vises for 5-axis machining" and "EWR series wire-cut vises" that dramatically reduce setup time, as well as "mag vises (magnetic chucks)" and "automation-compatible mag vises" that enable simultaneous processing of five surfaces. We integrate our role as the exclusive distributor in Japan for globally renowned manufacturers such as Taiwan's "Earth Chain" and "Gintec," and the American "Paitape," with our function as a fabless manufacturer of our own brand (FIRSTEC) produced in overseas partner factories, supplying high-precision products that meet the needs of the field. Not only do we sell products, but we also provide proposals for optimal jig configurations based on machining conditions, loan demo machines, and extensive support for implementation. With a comprehensive after-sales service system that includes quality assurance, repair, and maintenance, we strongly support our customers' productivity improvement and labor-saving efforts.
