Understanding ER Collet Specifications
| Collet Size | Length (mm) | Diameter (mm) | Clamping Range (mm) |
|---|---|---|---|
| ER-11 | 18 mm (0.71") | 11.5 mm (0.45") | 0.5–7 mm (0.020–0.276") |
| ER-16 | 27.5 mm (1.08") | 17 mm (0.67") | 0.5–9 mm (0.020–0.354") |
| ER-20 | 31.5 mm (1.24") | 21 mm (0.83") | 1–13 mm (0.039–0.512") |
| ER-25 | 34 mm (1.34") | 26 mm (1.02") | 1–16 mm (0.039–0.630") |
| ER-32 | 40 mm (1.57") | 33 mm (1.30") | 1–21 mm (0.039–0.827") |
| ER-40 | 46 mm (1.81") | 41 mm (1.61") | 3–26 mm (0.118–1.024") |
There exists a variety of collet types that may resemble ER collets. If your collet resembles an ER collet yet does not conform to the specifications listed above, it may belong to a different category altogether.
Key Considerations When Using Collets
Pro Tip: Always ensure the collet fits into the nut before inserting it into the chuck. The eccentric ring within the nut locks into the collet's groove, facilitating self-ejection. To extract the collet, simply tilt it.

Exploring Collet Capacity and Its Importance
The capacity of a collet determines its functionality in various machining tasks. Collets are available in a wide range of dimensions, making them suitable for a vast array of applications in industries such as milling and drilling. Using the appropriate collet size for the job ensures proper grip on the tool, significantly affecting cutting accuracy and tool life. Misapplication of collet sizes can lead to poor performance and premature wear on cutting tools.
Common FAQs About Collet Capacities
- How do I choose the correct collet size? Ensure the cutting tool's diameter matches the collet's clamping range for optimal performance.
- Can different brands of collets be mixed? While all ER collets conform to DIN standards, mixing components from non-ER systems may yield inconsistent results due to varying tolerances.
- What is the maximum clamping capability of ER collets? The maximum clamping ability varies by collet size, and it is advisable to refer to specific collet specifications for accurate data.
