You mean it trips a B type 20A MCB?

Yes. Fine elsewhere on re-wireables. Makita.

My workshop socket outlets are end fed so limited to 20 amps.

My previous workshop initially had a 20A MCB protected socket circuit,
and things like my 3kVA site transformer would trip that on switch on
about one time in five. Its fine on a B32 or C20 though.

Fuses don't nuisance trip. Get rid of the newfangled ****.
