Mills
 |
The Watermelon Mill is used to mill through collapsed casing and liners. This mill has a tapered top and bottom to allow reaming both up and down. A connection on the bottom allows a stinger to be run below the mill to keep it centered. This centering prevents cutting out of the casing or sidetracking. Watermelon Mills are often run piggyback with a long tapered mill as a pilot. Click here to see Halford's Tapered Mills. |
