Relton Corporation has been a quality source for cutting tools and fluids since 1946, beginning from the creation of their production-grade long-lasting hole saw. Relton's brazed carbide hole saw drills up to 100 times more holes than comparable high speed or bi-metal models, making it the desirable option for production applications. All saws, drills, cutting fluids and oils are proudly manufactured in Arcadia, CA, and readily available at one of Relton's 13 North American distribution warehouses.
