Thanks to the OP for posting it.

• The file starts with 255 tool records (#0-254).
• Each record is variable length.
• The end of the file is padded with 255 bytes of 0x01

Tool record file format:

• first byte is length of name (N)
• next N bytes is name
• 8 bytes ignored
• 8 bytes diameter double
• 26 bytes ignored
• 8 bytes diameter wear double
• 8 bytes height double
• 8 bytes height wear double

Improvements

Read the fill as one bytearray, close the fill and process, same for write.
