That is fine. Sounds like a lot of loft, though. A 5 or 6 iron might work better 🙂

Status of a Chipper
Q.What Rules apply to "chippers"?
A.A "chipper" is an iron club designed primarily for use off the putting green, generally with a loft greater than ten degrees. As most players adopt a "putting stroke" when using a chipper, there can be a tendency to design the club as if it was a putter. To eliminate confusion, the Rules which apply to "chippers" include:
The shaft must be attached to the clubhead at the heel (Appendix II, 2c);
The grip must be circular in cross-section (Appendix II, 3(i)) and only one grip is permitted (Appendix II, 3(v));
The clubhead must be generally plain in shape (Appendix II, 4a) and have only one striking face (Appendix II, 4d); and
The face of the club must conform to specifications with regard to hardness, surface roughness, material and markings in the impact area (Appendix II, 5).
