If you're running a CNC router or a plunge router with a 1/4-inch collet, this 6-piece spiral bit set is a solid arsenal for your shop.

You get three types of bits: upcut, downcut, and compression (which does both up and down in one bit)—all with a 1/8-inch cutting diameter and two flutes.

That means you've got the right bit for side milling, finish passes, grooving, slots, and dados, no matter what your project needs.

The bits are made from solid carbide with a Nano blue coating that boosts hardness and heat resistance, so they last about 2.5 times longer than uncoated bits.

The upcut pulls chips up for clean bottom edges, the downcut pushes them down for a smooth top surface, and the compression bit gives you the best of both worlds—clean edges on both sides of the material, which is gold for plywood and laminates.

They cut through plywood, oak, MDF, hardwoods, and even metals like aluminum alloy, tool steel, and cast iron—so they're super versatile.

Each bit comes in its own labeled storage case, so you can keep them organized and protected.

Clear size info is printed right on the shank too, so you never grab the wrong one.
