Bosch - 1/2" shank 3/4" tongue and groove bit (Rating: 1)

I purchased this bit because it had three cutters on each blade. It also promised to be a decent bit because of being adjustable. Well not quite what I thought. After 10 feet of tongue cutting one of the carbide tips snapped in half. My 5 year old was in the garage so fortunately it didn't get him. Usually if carbide fails it detaches completely. This tooth literally cracked in half. In short go with another brand. It will be getting returned
