With the Bahco 3830-89-VIP Sandflex hole saw, you cut clean and accurate 89 mm circular holes across wood, plastics, and metals, including stainless steel. Its rugged bi-metal build with 8% cobalt delivers superior wear resistance, preventing stripped teeth when creating openings for pipework or ventilation ducts. The 4/6 teeth per inch tooth geometry reduces vibration for a smooth cut up to the maximum 38 mm cutting depth. Practical side knockout slots allow you to pop out trapped slugs immediately, keeping your workflow fast and productive once mounted to a compatible arbor via the internal thread.
