What are 16C Collets?

16C Collets are industrial-grade workholding collets used primarily in CNC lathes and turning centers. They offer higher clamping capacity and rigidity than 5C collets, making them ideal for heavy-duty and high-precision machining. Learn more at pactoolsusa.com.

How are 16C collets different from 5C collets?

16C Collets have a larger body diameter (1.750") and longer nose, allowing for greater holding capacity—up to 1-5/8" for round stock. They also typically use a larger drawtube for more powerful clamping, making them better suited for high-volume production. Compare sizes at pactoolsusa.com.

What types of machines use 16C collets?

16C collets are used in high-performance CNC lathes, collet block fixtures, and bar-fed turning centers. They are favored in applications requiring quick part changeover and precise concentricity. Check compatibility at pactoolsusa.com.

What shapes and sizes do 16C collets support?

16C collets are available in round, hex, and square configurations. They typically support up to 1-5/8" round, 1-3/16" hex, and 1-1/8" square stock. Emergency (machinable) collets are also available for custom shapes. View full options at pactoolsusa.com.

What are emergency 16C collets?

Emergency 16C collets are soft collets made from steel or brass that can be bored to custom shapes for non-standard workpieces. These are perfect for short runs or odd profiles. See custom solutions at pactoolsusa.com.

What are the benefits of using 16C collets?

16C collets offer higher clamping force, better rigidity, and support for larger parts compared to smaller collet types. They ensure excellent part concentricity and are well-suited for production runs. Discover benefits at pactoolsusa.com.

Frequently Asked Questions

1. What is a 16C collet and where is it typically used? ▼

ER collet holders A 16C collet is a precision workholding device commonly used in CNC lathes and turning centers to grip bar stock or round parts securely.

2. How does a 16C collet differ from an ER collet? ▼

ER collet holders Unlike ER collets, 16C collets are larger, more rigid, and used for workholding rather than toolholding—ideal for heavy-duty turning operations.

3. What clamping capacity do 16C collets offer? ▼

ER collet holders Standard 16C collets can hold material up to 1.625 inches in diameter, offering excellent grip strength and repeatability.

4. Can 16C collets hold irregular shapes like hex or square stock? ▼

ER collet holders Yes, 16C collets are available in round, hex, and square bore options, making them versatile for various part geometries.

5. Are 16C collets part of any upgrade or trade-in programs? ▼

ER collet holders Some vendors include them in their ER collet trade in in USA campaigns, especially when modernizing turning center workholding systems.

6. How do you maintain the accuracy of a 16C collet? ▼

ER collet holders Regular cleaning, proper lubrication, and avoiding overtightening are key to maintaining gripping precision and extending the collet's life.
