Nowadays, the metalworking industry underwent several important changes that should bring the cutting tool configurations to the forefront of tool design and implementation. WSS has perfected the technology of tool making so practically any desired design of rotary cutting tools can be produced with a very tight tolerance. Many manufacturing companies have updated their machines, fixtures and tool holders. Modern machines used today have powerful rigid high speed spindles, high precision feed drives and shrink-fit tool holders. A wide range applications of rotary cutting tools: automobile engine cylinder block & head, valve guide pipe, seat bottom holes & tube hole, seat cone, housing of gearbox, gears, output shaft, etc.
