200160 | ER COLLETS

Q: What material are inner collets made from, and where are they used?

Pactools ER collets are made from high-grade spring steel, offering excellent hardness and flexibility. They are commonly used in milling, drilling, and tapping operations for precise tool holding.

Q: How do I choose the correct inner collet size?

Select a collet size that matches your tool shank within a ±0.5 mm tolerance. Using a collet close to the shank diameter ensures a secure and accurate grip.

Q: What is the lifespan of a collet, and how can I detect wear?

Collets typically last over 1000 cycles with regular use. Signs of wear include tool slippage or poor surface finish—if noticed, it's time to replace the collet.

Q: What is the benefit of a coolant flush (jet spray) collet?

Jet spray collets provide direct coolant flow to the cutting area, improving chip removal and keeping the tool cooler during operation.

Q: How should I maintain an inner collet?

After use, clean the collet with a mild solvent and apply light oil to prevent rust. Always store collets in a dry, clean environment.
