Diamond barrel lapping tools are an inexpensive alternative to higher cost bore finishing tools. Each lap consists of three parts; the expansion screw, the brass diamond coated expansion sleeve and the steel shank or handle. These tools are ideal for sizing and honing bores and holes in hard steels, glass, ceramics, carbides and other hard abrasive materials. At Triatic, we offer our diamond-plated barrel laps in a variety of diameters and grit sizes, ensuring that you can be prepared for whatever your job requires. These expansion barrel laps ensure fast, accurate lapping of long or short through holes in diameters from 1/8” to 1-1/2”. These laps can expand to 15% or more of their original diameter by simply turning the adjusting screw by hand or with a wrench.
Our diamond barrel lapping tools are manufactured in our factory here in the U.S.A using only the highest-quality materials to ensure that your tool will last! Browse our options today!
