Based on my EXPERIENCE, this router bit has been a game-changer for my woodworking projects .The industrial-grade material guarantees long-lasting durability while the radius groove shank provides precise maneuvering for flawless results. Although it comes with a higher price tag than some competitors, it's worth the extra investment. My only con is that it's not beginner-friendly and requires some experience to effectively utilize. Overall, an excellent addition to any DIY arsenal in the cutting tools category..
