What are DNA (Dead Nut Accurate) Collets?

DNA Collets are ultra-precision ER collets engineered for exceptional concentricity—typically within 0.0002" (5 microns) or better. They are ideal for high-precision machining, where tool runout must be minimized for tight tolerances and extended tool life. Discover more at pactoolsusa.com.

How are DNA collets different from standard ER collets?

Unlike standard ER collets (which typically offer 0.0005" or greater runout), DNA collets undergo fine grinding and individual inspection to achieve exceptional concentricity. This results in superior part finish, improved dimensional accuracy, and reduced wear on spindle bearings. Compare specs at pactoolsusa.com.

When should I use a DNA collet instead of a regular collet?

Use DNA collets in applications involving micro-milling, tight-tolerance boring, high-speed machining, or when you're working with expensive materials where precision is critical. They’re also ideal for finishing passes. Learn usage cases at pactoolsusa.com.

Are DNA Collets compatible with standard ER holders?

Yes, DNA collets are fully compatible with standard ER collet chucks and toolholders. No special adapters are required—just improved accuracy within the same ER system. Check compatibility at pactoolsusa.com.

How do I maintain the accuracy of DNA collets?

To preserve concentricity, always clean the collet and holder thoroughly before use. Avoid overtightening, rotate collets periodically for uniform wear, and store them in protective cases to prevent nicks. Detailed care tips are available at pactoolsusa.com.

Do DNA collets support coolant-through applications?

Some DNA collets are available in sealed or coolant-through configurations, allowing them to be used in high-speed, high-pressure coolant systems without compromising accuracy. Confirm specifications at pactoolsusa.com.
