BINOTA Concrete Hole Saw, Kit 40 65 80 100 125 MM, Arbor SDS Plus 110mm and SDS MAX 160mm, for Masonry Cement Wall Brick Sands Stone Sable-Rock Self-Leveling

The BINOTA Concrete Hole Saw kit comes with five hole saws of varying sizes and two arbors. It is designed for use with an SDS hammer drill, and it is recommended to keep the area wet while drilling to avoid overheating. Reviewers had mixed experiences with this product, with some reporting teeth breaking off after one use while others successfully drilled multiple holes. Some customers had difficulty with the set screw being too long, and the square cut shaft making it hard to put into a three jaw chuck. However, the cutting tips are carbide and should hold up if not forced with excessive pressure, making it suitable for cutting through stucco and masonry without embedded metal. Patience is key, as it is a slow process even with a hammer drill, but one customer reported drilling through a 7-inch thick concrete wall in approximately 15 minutes. Overall, the BINOTA Concrete Hole Saw kit is a budget-friendly option for those looking to make holes in concrete, but it may not be the most durable or user-friendly option on the market.
