The HOZLY Flutes Spiral Carbide router bit is a game-changer in the cutting tools category. According to my experience this bit is super efficient, precise, and durable. The six flutes are sharp enough to cut through wood, plastic, and even soft metals. The carbide material is sturdier than most bits out there, meaning it will serve you for long. However, the shank cut could be better for a snug fit .Despite that, I highly recommend this router bit!See full review
