Frequently Asked Questions
1. What does ER collet stand for?
ER collet stands for ‘Extended Range’ collet. ER collets are used to hold a variety of cutting tools like an end mill, drill, and tap in the machine's spindle.They are very famous because they are flexible and can hold any odd-sized cutting tools in place and which prevents vibration. ER collet available in different sizes and accuracy such as Standard, High-precision and Ultra-precision and available series are ER8, ER11, ER16, ER20, ER25, ER32, ER40, ER50. ER collet is used in many industries like CNC machining, milling, drilling, metalworking, Aerospace, Automotive, Woodworking and so on.
2. What materials are ER collets made of?
ER collets are made from high-quality materials for durability, precision, and wear resistance. Common materials include spring steel, alloy steel, hardened tool steel, and stainless steel. Spring steel is the most widely used for its strength and long service life. Alloy steel offers superior hardness for heavy-duty applications, while stainless steel provides corrosion resistance in moist or chemical environments. These materials are heat-treated for precision and reliability. Accu-fix Precision Tools manufactures high-quality collets to strict accuracy standards for better performance.
3. Which are the types of ER collets?
ER collets are clamping tools used in CNC and precision machining. Types include Standard, Ultra-precision, High-precision, Sealed, Coolant, and ER Tap collets. The Standard ER collet is the most commonly used, while Ultra-precision ER collets minimize runout for high-accuracy tasks. High-precision ER collets are designed for operations requiring ultra-accurate machining. Coolant ER collets allow coolant-through cutting tools, and Sealed ER collets prevent coolant leakage for wet operations. Accu-fix Precision Tools offers Standard, High-precision, Ultra-precision ER collets , and collet sets.
4. How do I clean and maintain an ER collet?
To maintain ER collets , remove them from the nut and spindle, and use compressed air to clear dust, chips, and dirt. Wash the collet with a mild cleaning solution, brush gently, then rinse and dry to prevent rust. Inspect for damage and replace if necessary. For maintenance, oil the collet and nut threads to prevent rust, tighten to the recommended torque, and store in a clean, dry place. Regularly check for wear and use the collet within its specified range. Proper care ensures accuracy, reliability, and a longer lifespan. At Accu-Fix Precision Tools, we recommend maintaining your ER collets for better performance.

9. What is the difference between ER and TG collet?
TG collet have a higher clamping force that makes them better for heavy-duty machining tasks and high-speed operations.Where as, ER collets provide decent clamping force, that makes them a general purpose machining tool. TG collet have a narrow clamping range while ER collet have a wide clamping range.
10. What is the difference between ER and SK collet?
The common difference between ER and SK collet is that SK collet provides higher clamping force that is why they are best for heavy machining and rigid tool holding. While ER collet offers decent clamping force that is why they are perfect for general purpose machining.SK collet have fixed clamping range while ER collet have a wider clamping range.
