Item No. R303R : ISO size RNGN090300, Round 9.52mm(3/8") with thickness 3.18mm (1/8") Single Sided laminated CBN insert Idea for cast iron heads with steel precombustion chambers refinishing and resurfacing. RPM speed with a 14” (355.6 mm) cutter range from 600-700 RPM and with an 18” (457 mm) cutter range from 500-600 RPM. Laminated CBN Inserts consist of a layer of PCBN composite sheet materials bonded to a carbide substrate, reduced edge build-up allows for high precision cutting. PCBN composite sheet material is also an artificially synthesized material exceeded in hardness only by diamond, while still offering superior wear resistance to carbide in certain applications, which is much suitable for interrupted cutting and difficult-to-machine materials.Please clean all tooling thoroughly before installing a new CBN inserts. Metal chips, debris or dirt can cause the insert to become misaligned in the tool holder and possibly damage the insert or the work piece. When the cuttin
