Woodworkers, if you need to carve deep, rounded grooves or hollows, this Magnate Core Box Router Bit is a pro-grade tool. It has a 7/8 inch cutting diameter and a super useful 1-1/4 inch cutting length, making it 'extra deep' for serious material removal. It's built with two industrial-grade micrograin carbide tips brazed onto a high-carbon steel body, so it stays sharp and handles hardwoods, softwoods, plywood, and chipboard like a champ. The 1/2 inch shank provides great stability in your router. The design includes wide gullets to clear chips quickly and radially relieved cutting edges to prevent burning and rubbing. Remember to use the shortest bit possible for your project to minimize vibration. This is a heavy-duty bit designed for precision and long-lasting performance in your shop.
