Name the measurement, not just the number
Working length, overall length and diamond-section dimensions describe different parts of a tool. Copy the manufacturer’s labels and units with each value, and attach the drawing when possible.
For example, a request for a ‘50 mm tool’ is ambiguous: the number might mean diameter, working length or overall length. Write the dimension name next to the measurement instead of relying on context.
Confirm the connection and direction
Supply the connection designation exactly as documented, including thread direction where specified. A similar diameter does not prove two threads are interchangeable. Do not force a tool into an apparently matching fitting.
Include the machine model, tool holder information, existing manufacturer reference and a label photograph. If a connection is uncertain, ask for confirmation before choosing a substitute.
Describe the operation
Say whether the tool is for drilling, sink machining, routing, profiling or rebating. Provide the material and thickness along with the required geometry.
Confirm operating parameters and machine compatibility against the exact tool documentation. This guide is a measurement checklist, not a source of speeds, feeds or safe operating limits.
Manufacturer references
Use the instructions for your exact product and machine. Linked ranges are not confirmation of compatibility.
