The "EM Continuous Water Method" is a groundbreaking technique that uses end mill cutting tools for continuous water construction. Conventional methods used a circular blade called a "hole saw," which could only perforate pipes in a limited round shape. The "EM Continuous Water Method" allows for perforation by moving the end mill tool at a "point," enabling the cutting of pipes in free shapes and sizes. *We are currently offering a comprehensive catalog that explains the "EM Continuous Water Valve Method" for free!
