Frequently Asked Questions
1. What are DNA (Dead Nut Accurate) Collets?
Dna (Dead Nut Accurate) Cllets 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 Pactools USA.
2. How are Dna Collet different from standard Er collets?
Dna Collet differ from standard ER collets by offering superior runout control—typically 0.0002" or better, compared to 0.0005" or more for standard types. Each DNA collet is finely ground and individually inspected to ensure maximum accuracy, resulting in improved surface finish, dimensional precision, and reduced spindle wear. Compare specs at Pactools USA.
3. When should I use a DNA collet instead of a regular collet?
Dna Collet should be used in micro-milling, tight-tolerance boring, and high-speed machining applications. They are particularly effective when working with high-value materials or when finishing passes require minimal runout. Learn usage cases at Pactools USA.
4. Are Dna Collet compatible with standard Er holders?
Dna Collet are fully compatible with standard ER collet chucks and toolholders. No special adapters are required—they provide enhanced accuracy within the same Er system. Check compatibility at Pactools USA.
5. How do I maintain the accuracy of Dna Collet ?
Dna Collet should be cleaned thoroughly before each use to maintain concentricity. Avoid overtightening, rotate collets periodically for even wear, and store them in protective cases to prevent nicks or damage. Detailed care tips are available at Pactools USA.
6. Do Dna Collet support coolant-through applications?
Dna Collet are also available in sealed or coolant-through configurations, making them suitable for high-speed, high-pressure coolant systems without sacrificing accuracy. Confirm specifications at Pactools USA.
