摘要 |
A method of cutting a tubular includes providing a rotatable cutting tool in the tubular, the cutting tool having a blade with a cutting structure thereon; extending the blade relative to the cutting tool; rotating the cutting tool relative to the tubular; guiding the cutting structure into contact with the tubular; cutting the tubular using the blade; and limiting extension of the blade. A rotatable blade for cutting a tubular includes a blade body extendable from a retracted position; a cutting structure disposed on a leading edge of the blade body, the cutting structure configured to cut the tubular; a stop on a first surface of the blade body; and an initial engagement point on a second surface of the blade body, the initial engagement point configured to guide the cutting structure into contact with the tubular. |
