Product details
R8 collets hold a selected tool shank directly in an R8 milling spindle. This series is organized around bore size and the catalog's metric or inch selections, rather than an ER nut size. Use the existing spindle and drawbar details to confirm the replacement before choosing an individual collet or an assortment.
Bore-based selection
Order by actual tool shank diameter and measurement system, not cutter diameter.
Replacement matching
Send the existing collet code or drawing when replacing a worn or missing size.

Models and specificationsIs an R8 collet the same as an ER collet?
No. This series connects to an R8 spindle. ER collets require a matching ER holder and nut.
Should I order by the cutter's cutting diameter?
Order by the shank being clamped. A cutter's cutting diameter may differ from its shank diameter.
Are all catalog inch sizes ready to order?
The catalog records an inch range, but individual bore availability and the final R8 drawing must be confirmed before order.
What should I send for a replacement?
Send the collet marking, measured tool shank size, spindle information and drawbar details, preferably with a photograph.
