Afternoon all,

Last night I had a proper crash moment and my favourite insert endmill (16mm dia) is now less endmilly and more scrap.
I still have a load of apkt inserts, so a new body is all I need.
Should be simple however the insert size is a mystery. The only insert box I have with no label is the apkt one...

My google-fu is weak today and I haven’t managed to find a chart with measurements that would allow me to determine what I have.

I think they are 1604, but it seems all the bodies in the size I use take 1003.

Can anyone tell me what I need to measure to know?

They come out about 1mm longer overall than their code number so 1003 will be approx 11mm lone and 1604 about 17mm long. Corner radius will have a slight affect on length so can't be exact, the 10 and 16 are the long edge measurements.

Probably. You should measure across corners on one long edge not the diagonal as you show here.
