Precision EOC16 Collet
Royce Ayr EOC16-1/4 is a 1/4 in precision EOC16 collet for securely clamping compatible round tool shanks in EOC16 toolholding systems. Royce states its collets conform to DIN 6388 and should be snapped into the nut before the nut is threaded onto the tool holder. EOC16 family envelope dimensions are retained from DIN 6388 Perske-style technical literature because the current Royce online series no longer exposes an EOC16 row.

Main Product Description
The Royce Ayr EOC16-1/4 is a precision EOC16 collet sized for a 1/4 in round tool shank. It is intended for compatible CNC-router toolholders and collet nuts using the EOC16 system.
Royce states its collets conform to DIN 6388. The EOC16 family-identification envelope is 40 mm overall length and 25.5 mm outside diameter. Current Royce SYOZ/EOC listings do not expose EOC16, so the EOC16 envelope is corroborated from DIN 6388 Perske-style collet documentation rather than inferred from another family.
For installation, snap the collet into the nut first, then thread the nut onto the tool holder. Verify nominal shank size, clean mating surfaces, correct holder/nut family and proper tightening procedure before running the machine.

Product Highlights
DIN 6388 · EOC16
The EOC16 family envelope is 40 mm OAL by 25.5 mm OD, supporting positive collet-family identification.
Correct Nut Installation
Royce specifies snapping the collet into the nut before threading the nut onto the tool holder.
Compatibility & Installation Notes
Use only with compatible EOC16 toolholders and collet nuts. Confirm the nominal 1/4 in tool-shank size before clamping. Keep the collet, nut and holder mating surfaces clean; snap the collet into the nut before threading the nut onto the holder; and do not mix collet families that may appear visually similar.
Precision EOC16 Toolholding
Royce Ayr EOC16-1/4 combines a 1/4 in nominal tool-shank size with the verified EOC16 family envelope and DIN 6388 toolholding standard.
Correct holder-family matching, clean seating, proper nut assembly and appropriate tightening are essential to concentric clamping and reliable CNC-router tool retention.
