DNA Collets from a top Precision tool supplier in Wisconsin are designed from premium, hardened spring steel and precision-ground to deliver exceptional concentricity and minimal runout. These collets ensure superior tool holding accuracy for finishing and high-speed operations. PAC precision tools DNA collets provide unmatched stability, repeatability, and performance in demanding machining environments.
Features:
- ccuracy: ≤ 3 Micron (0.0001” TIR) or better
- Ultra-low runout for precision machining
- Optimized slot geometry for balanced clamping pressure
- High elasticity for consistent gripping performance
- Compatible with standard ER collet systems (ER16 through ER40)
- Series available: ER8 through ER40
- Hardened and tempered spring steel construction
- Precision-ground internal and external surfaces
- Corrosion-resistant surface treatment for durability
- DNA/RTX collets have a much shorter projection outside of the collet pocket
- More rigid hold for small diameter tools and repeatable accuracy
- Longer tool-life and superior tool performance!
- DNA/RTX collets work in standard ER collet chucks - only a collet and nut required
- METRIC & INCH sizes
- Only the nominal size can be clamped
PAC Precision Tools DNA Collets are ideal for high-speed finishing, precision milling, drilling, and reaming operations. Made to improve surface finish, reduce vibration, and extend tool life, they provide superior performance where maximum accuracy is critical.
Frequently Asked Questions
1. What are DNA (Dead Nut Accurate) Collets, and how do they differ from standard ER collets?
DNA collets are high-precision ER collets designed to achieve extremely low runout using a “dead nut” tightening principle. Unlike standard ER collets, the nut does not rotate against the collet during tightening, which reduces tool shift and improves accuracy. As a precision tools supplier in the USA, PAC Precision Tools offers DNA collets for ultra-accurate machining.
2. Which ER sizes are commonly available for DNA collets at PACTools?
DNA collets are commonly available in ER8, ER16, ER20, ER25, ER32, and ER40 sizes. These sizes cover most precision machining needs and are suitable for small to medium tool diameters used in CNC operations.
3. How should DNA collets be maintained to ensure long-term performance?
DNA collets should be cleaned after each use to remove chips and coolant residue. Avoid over-tightening, store them in a dry environment, and inspect them for wear regularly. Proper care helps maintain low runout and consistent clamping accuracy.
4. Which industries commonly rely on DNA collets for high-accuracy machining?
Industries such as aerospace, medical device manufacturing, mold making, electronics, and precision engineering frequently use DNA collets. These industries require tight tolerances, superior surface finish, and repeatable accuracy in CNC machining.
5. What maintenance guidance does PACTools provide to customers for optimal performance?
PACTools advises customers to keep collets clean, use correct torque settings, and avoid damaged tool shanks. Regular inspection and proper storage should also be emphasized. A CNC tools distributor in the USA that provides clear maintenance guidance helps customers achieve better results and longer collet life.
