What is kerf?
Kerf is the width of material removed by the saw (or waterjet) as it cuts. In stone fabrication it is commonly about ¼". Nesting must leave kerf between pieces; ignoring it overstates how much countertop fits on a slab.
Effect on yield
Every cut corridor costs kerf. Dense nests with many small pieces lose more to kerf than a few large straights. Yield estimates that use gross slab SF without kerf will order short.
From the shop floor
We publish what estimators tell us about these pages, including the parts where the software was wrong. If you run takeoff in a shop and this page got something right — or got it wrong — send it to us and it goes here with your name on it, or without it if you prefer.
