PCD Reamer vs Drill

What is Drill?

A drill creates the hole. It is not normally the final operation for precision bore tolerance and fine surface finish.

What is PCD Reamer?

A PCD reamer finishes a prepared hole to improve size, roundness and surface finish.

Key differences

Drilling focuses on hole creation. PCD reaming focuses on final precision hole finishing.

Which should you choose?

Use drilling before reaming, then use a custom PCD reamer when the final bore is critical.
