Taper String Mill
The taper string mill is designed for:
- Removing irregularities and metal debris from the internal surface of tubing and casing strings;
- Cleaning and reconditioning casing windows;
- Chamfering the inner edges of pipe;
- Reaming elliptical or out-of-round pipe sections to restore the original internal diameter;
- Milling damaged casing or tubing during workover and remediation operations in oil,
gas, and geological exploration wells (excluding lightweight drill pipes).
