This downcut spiral bit from BINSTAK is a workhorse for CNC routing and woodworking.

It's got a 1/2-inch shank and 1/2-inch cutting diameter, with a generous 3-inch cutting length and 5 inches overall – plenty of reach for deep mortises and slot cutting.

The solid carbide construction with TAC coating gives it up to 2.

5 times the life of uncoated bits, with better heat resistance and hardness.

Downcut geometry pushes chips downward, so you get clean edges on the top surface with minimal tear-out – great for dados, mortises, and plunge cuts where top finish matters.
Works beautifully on softwoods, hardwoods, plywood, MDF, laminate, oak, and even aluminum if you take it easy.

Accuracy is rated at ±0.

02mm, so your cuts stay precise.
Suitable for CNC machines, router tables, and handheld routers.
Good bit for pro shops and serious hobbyists alike.
