A cone hole in lumber refers to a small, circular hole that is typically found in softwood lumber, such as pine, spruce, or fir. The hole is caused by the presence of a small, cone-shaped projection on the tree, which falls off or is removed during the milling process.
Cone holes are usually small in size, typically less than an inch in diameter. They are often located near the edge of the board and may be difficult to see if the lumber has been planed or sanded. While cone holes do not typically affect the strength or structural integrity of the lumber, they can have an impact on the appearance of the wood, particularly if the holes are numerous or large.
