The WSOOX Adjustable Forstner Professional Diameter bit is a game-changer in my woodworking experience. Based on my observations this bit is versatile, perfect for making clean AND precise holes with a range of diameters .The adjustable length drill depth is also a plus, as it allows me to easily adjust the depth according to my desired hole length. However, the price is somewhat higher than other Forstner bits in the market. Overall, this bit is a must-have for serious woodworkers..
