3M Green Diamond Fibre Optic Lapping Film, 279.4 mm x 229mm, 0.1 μm Grade

For improved signal transmission, use this lapping film from 3M to keep your fibre optic cable tips sharp. It features a diamond abrasive that's reliably rock hard, so it will cut through ceramic ferrules like a hot knife through butter. The film comes as a sheet with dimensions of 279.4 (L) x 229mm (W), so there's enough to go around for numerous jobs. A small 0.1μm grit size gives a smooth and uniform finish.
