Ultra Precision ER50 Coolant Sealing Collets
Chongde ER Coolant Collets uses the difference of grooves to achieve the function of surrounding sealing and center thru coolant. ER thru coolant collets made to be used with thru-coolant tools. It allow greater water pressure through the collet. The maximum water pressure can be 30Mpa. The gripping range of spring collet is 1mm or 0.040”, commonly used in tool holding. The Non-standard hole size can be customized.
Features:
1. Material: JIS-SUJ2
2. Hardness: 46-50HRC;
3. All collets are precision ground for less than 0.0002" (0.005mm )of indicated runout；
4. The maximum water pressure can be 30Mpa;
5. Commonly used with thru-coolant tools in tool holding.
