It was used when expanding from Φ 28 to Φ 33. It was a beautiful finish without any problem because it was an aluminum frame door. If it feels like this, it seems to be a problem with a steel door. I hope the step drill of this size is a bit cheaper.

Sharpness is wonderful, the flatness of the surface of the processed hole is the highest ever. I will also buy it.
