Order LookupBoring Bars & Sets
Available1,624 products
Boring bars are single-point cutting tools used with lathes, CNC lathes, turning machines, and machining centers to size, straighten, and finish the inside diameter of drilled or cast holes. Boring bar sets include multiple bars, each with a different-sized cutting tip. Boring bar backstops fit into a lathe's toolholder to ease tool changes when using different boring bars on the same machine.
