ER spring collet <German DIN6499 standard>
Vibration accuracy ranges from ±15 microns to ±20 microns! A user-friendly product that pursues low cost.
The "Fast Tech ER Collet" is a spring collet that conforms to the DIN6499 standard with an 8-degree taper. The precision is standard grade. While Japanese-made ER spring collets have runout precision of ±0.003mm to ±0.005mm, this product has a runout precision of ±0.015mm to ±0.020mm. Nevertheless, it is more precise than a drill chuck and can securely hold drills. It is a user-friendly product that prioritizes low cost over high specifications for runout precision. 【Features】 ■ The Fast Tech mini mini collet chuck holder excels in machining deep and narrow areas (the shank diameter and tip diameter are the same or nearly the same). ■ With a collet shrinkage allowance of 1.0mm, it can be safely used even with straight drills. *For more details, please download the PDF or feel free to contact us.

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.
