Description
Product Overview
The Yaocom ER11 Spring Collet Set is engineered to meet the demanding tolerances of modern CNC, milling, engraving, and router machines. Each of the 19 components is forged from 65 Mn spring steel, a material renowned for its high elasticity, wear resistance, and ability to maintain a consistent clamping force over thousands of cycles. The set includes fifteen precision‑ground spring collets ranging from 1 mm to 7 mm, as well as two imperial sizes—1/4″ and 1/8″—to accommodate a broad spectrum of tool shank diameters. With a thread size of M14 and a maximum cutting diameter of 7 mm, the collets provide a secure, repeatable grip that minimizes run‑out and maximizes surface finish quality.
Every collet is calibrated to an accuracy of 0.02 mm (0.0008 inches), ensuring that even the most delicate operations—such as micro‑drilling or fine engraving—are performed with confidence. The accompanying ER11 collet nuts feature a robust hex design that simplifies tool changes while preserving the integrity of the collet’s spring action. Packaged in a compact, durable box measuring 5.12 x 3.54 x 1.57 inches and weighing just 7.4 ounces, the set is both portable and ready for immediate deployment in any workshop.

Usage
This collet set is ideally suited for a variety of machining environments. In CNC routers, the ER11 collets provide a quick‑change solution for interchangeable end‑mills, allowing operators to switch between different tool diameters without sacrificing precision. For milling machines, the spring‑loaded design reduces the need for additional torque, making it easier to achieve tight tolerances on complex geometries. Engraving professionals will appreciate the consistent grip that eliminates chatter, resulting in cleaner line work and finer detail reproduction.
Beyond traditional metalworking, the set performs admirably in wood‑working and composite material applications where vibration damping is critical. The collets’ ability to hold both metric and imperial shank sizes makes them a versatile choice for mixed‑tool inventories, and the included nuts are compatible with most ER11‑type chucks found on desktop and industrial‑scale equipment. Whether you are a hobbyist building a home workshop or a production facility seeking to streamline tool management, this collet kit delivers the reliability and flexibility required for high‑volume, high‑precision tasks.
Why Choose Us
Choosing the Yaocom ER11 Spring Collet Set means investing in a product that combines rigorous engineering with practical usability. Our commitment to quality begins with the selection of 65 Mn spring steel, a grade that undergoes heat‑treatment processes to achieve optimal hardness and resilience. Each collet is inspected for dimensional accuracy using calibrated micrometers, guaranteeing that the advertised 0.02 mm tolerance is consistently met across the entire range.
We understand that downtime can be costly, which is why our collet nuts feature a user‑friendly hex interface that allows for rapid installation and removal without the need for specialized tools. The set’s comprehensive size coverage eliminates the need to purchase multiple single‑size collets, reducing inventory complexity and overall cost. Additionally, Yaocom provides responsive after‑sales support, offering technical assistance, replacement parts, and a satisfaction guarantee that underscores our confidence in the product’s durability.
Our collet set is also designed with environmental responsibility in mind. The steel used is recyclable, and the packaging is constructed from recycled cardboard, aligning with sustainable manufacturing practices while maintaining the protective qualities needed for safe shipping.

FAQ
What machines are compatible with the ER11 collet set?
The set works with any equipment that accepts ER11‑type chucks, including CNC routers, milling machines, engraving machines, and many desktop CNC kits.
Can I use the collets for both metric and imperial tools?
Yes. The set includes fifteen metric collets (1 mm‑7 mm) and two imperial sizes (1/4″ and 1/8″), allowing you to secure a wide variety of tool shanks.
How do I maintain the collets for optimal performance?
Keep the collets clean and free of debris, avoid excessive impact forces, and periodically inspect the spring steel for signs of wear. Simple hand‑washing with mild detergent and thorough drying is sufficient for routine maintenance.
Is there a warranty or guarantee for this product?
Yaocom offers a one‑year limited warranty covering manufacturing defects. If a collet fails due to material or workmanship issues within this period, we will provide a replacement at no charge.
Do the collet nuts require any special tools for installation?
No special tools are needed. The hex‑shaped nuts can be tightened or loosened with a standard 5 mm Allen key, making tool changes quick and straightforward.
