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.
