No, there is no such thing as SHA1 cracker hash. Currently, there are two main issues with using the hash function for security purposes (not specifically password hashing):
It is a very fast hash, meaning a brute force attack will run much more quickly than it would if you were to correctly use a slow KDF. The fact that SHA-1 is fast does not allow you to crack any password, but it does mean you can attempt more guesses per second.
It is vulnerable to collision attacks, as Google showed. A collision attack allows someone to create two inputs with the same hash. However, it does not allow them to reverse a hash or to modify an input without affecting the resulting hash. That would be a different kind of attack called a preimage attack, and SHA-1 is not vulnerable to that attack.
So no, you are not able to crack just any password that has been hashed with SHA-1 unless the password is short or weak. That does not mean you should use it for password hashing however, since it is so fast and is efficiently implemented on a GPU.
Cracking SHA-1 Hashes
Attacking (often referred to as cracking) SHA-1 hashes is most often performed using the same technique as any one-way hashing function. Computing possible matches of the original string as fast as possible to find a matching hash.
See the following chart to get an idea of the weakness in standard hashing algorithms for password storage. These show brute force attempts against a single hash. cudaHashcat is running on an NVIDIA 560 GTX GPU that is a few years old now, so consider these on the low end of what is capable.
Note the difference between hashcat and cudaHashcat against the same SHA-1 hash. You are reading that correctly MD5 hashes being brute forced at 1.8 billion per second.
