Ann Way ER11-04 Collet – Reliable Precision for Small-Diameter Tooling
The Ann Way ER11-04 collet is engineered to provide accurate and secure clamping for tools with a 4.0 mm diameter. Its compact and efficient design makes it ideal for high-speed micro-machining applications that require consistent accuracy, even in limited space.
Made in accordance with DIN 6499 / ISO 15488, the ER11-04 collet ensures a runout of ≤ 0.008 mm. This tight tolerance reduces tool vibration and significantly improves surface finish, tool life, and dimensional accuracy. Whether you’re engraving fine details, drilling micro holes, or machining miniature components, this collet provides reliable performance.
Thanks to its high-quality alloy steel construction and heat treatment, the ER11-04 is built for durability. It withstands prolonged use in demanding environments without compromising performance. The slotted design distributes clamping force evenly, preventing tool slippage and minimizing wear on both the tool and the holder.
This collet is widely used in jewelry making, dental labs, watch component manufacturing, electronics, and other precision industries. Its compact size and low runout make it a go-to solution for CNC routers, desktop mills, engraving machines, and micro lathes that operate with small-diameter tools.
In addition, the ER11-04 collet is fully compatible with all ER11 tool holders, extensions, and collet chucks. It offers great flexibility, especially for workshops that require frequent tool changes while maintaining machining quality.
