When I tried this hole cutter, I was impressed with its durability and efficiency. It made clean and precise holes through various materials easily. The bi-metal technology makes the saw more durable and long-lasting, while the plastic plywood makes it lightweight and easy to handle. However, the price point may be a bit high for those on a tight budget. Nonetheless, this hole saw is definitely worth the investment if you're looking for a reliable cutting tool in the Industrial and Scientific field.
