How to Choose the Right ER Collet Size
Method 1 – Measure Length
- Use a vernier caliper to measure the height of the ER collet.
- Match the height to the specification chart (e.g., 40 mm length = ER32).
Method 2 – Measure Outer Diameter
- Use a vernier caliper to measure the outer diameter of the collet’s edge.
- Match it to the chart (e.g., 32.9 mm outer diameter = ER32).
Applications
- CNC milling machines
- Boring machines
- Drilling and tapping setups
- Engraving machines
- General precision machining
