Kerf
Kerf is a term used to describe the material removed during a cutting process.
When cutting sections of material, a certain amount will be lost, usually between 2 and 5 mm. This is the kerf and it is the same width as the blade of cutter. For example in carpentry a kerf groove or cut is one that is as wide as the saw blade used to make it. The term may also be used in metalworking and stonemasonry.
The term kerf groove may also be used to describe a drip groove cut into the underside of a window or door cill to encourage water away from the wall. The width of the groove is defined by the size of the blade used to cut it.
