This is a pro-grade router bit for serious woodworking, CNC work, or machining plastics and aluminum. It's a solid carbide upcut spiral bit with a single flute (that's the \O Flute\ design). Solid carbide is super hard and holds a sharp edge way longer than high-speed steel bits, but it's also more brittle, so you need a rigid setup to use it.
The upcut spiral design pulls chips up and out of the cut as you work, which helps prevent clogging and gives you a cleaner cut, especially in materials like plastics and wood. It has a 21-degree helix angle. The cutting diameter is 1/8 of an inch (0.125\), the shank is 1/4 inch (0.250\) so it fits standard collets, and the overall length is 2 inches.
It's uncoated (bright finish), which is versatile for a lot of materials. If you're doing precise routing, engraving, or detail work in soft materials, this bit is a top-notch choice. Just make sure your router or spindle can handle it.
