I'll try the subquery and see how I go :)
Thanks!

It isn't in the SQL standard, and it would have undefined behavior: the sort order of a result set without ORDER BY is unspecified, so you would have no way to predict which rows DELETE would remove.
delete from table where x='1' limit 1000;
You could use a subquery to achieve this:
DELETE FROM table WHERE x IN (SELECT x FROM table ... ORDER BY ... LIMIT ...);
