Another tool making company supplied a quote with a shorter lead time?
A. It is likely that they are not quoting on a like-for like basis. Similarly, check that you are being quoted for a complete tool rather than just for tooling inserts, and that they have not compromised any important aspects of your original specification such as the tool life and quality. It is worth checking the Toolmakers credit rating and current references as some may happily offer (and miss) shorter leadtimes. If the supplier is outside the UK, beware the pitfalls regarding legal accountability and confidentiality.
