Royce Ayr ER32-14 is a 14 mm precision ER32 collet for securely clamping compatible round tool shanks in ER32 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.
14 mm nominal tool-shank collet for compatible ER32 holders and nuts, with family identification dimensions of 40 mm OAL and 33 mm OD.
Compatible ER32 toolholders and collet nuts. Verify the holder/nut family and nominal tool-shank size before installation.
The Royce Ayr ER32-14 is a precision ER32 collet sized for a 14 mm round tool shank. It is intended for compatible CNC-router toolholders and collet nuts using the ER32 system.
Royce states its collets conform to DIN 6388. The ER32 family-identification envelope is 40 mm overall length and 33 mm outside diameter.

Technical Specifications
ER32-14 is the 14 mm nominal tool-shank variant for the ER32 collet family.
The ER32 family envelope is 40 mm OAL by 33 mm OD, supporting positive collet-family identification.
Royce specifies snapping the collet into the nut before threading the nut onto the tool holder.
Use only with compatible ER32 toolholders and collet nuts. Confirm the nominal 14 mm 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.
Royce Ayr ER32-14 combines a 14 mm nominal tool-shank size with the verified ER32 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.
