Unique Tool Geometry & Premium Materials Make Our Spiral Bits Top Performers!

Our solid carbide spiral router bits are designed to provide remarkable performance and durability. They quickly slice through hard or soft wood, plywood and composites such as MDF or particle board. Manufactured using state-of-the-art computer controlled machinery; these micro-grain carbide cutters feature our optimal helix design and a stronger body that reduces vibration and lasts up to 300% longer than regular router bits. Unlike straight router bits, Infinity solid carbide spiral bits feature a helical spiral design that is continuously in contact with the workpiece, producing smoother cutting action and the cleanest results possible.

Upcut or Downcut, which bit style should you choose?

Upcut bits pull chips up and out of the kerf for faster cutting. This type of bit is ideal for high-volume shops but the workpiece must be securely clamped in place to prevent lifting. For work requiring a finer finish consider a downcut spiral bit.

Downcut bits don't clear chips as quickly as upcut bits but their downcut geometry pushes wood fibers down into the cut and leave a nicer quality top surface on your workpiece. They do require a slower feed rate. When used in a router table downcut bits actually push your material up.

Please note: The recommended depth of cut for any single pass is 1/2" of the diameter of the tool. For example, if you are using a 1/4" diameter cutter you should only take a 1/8" depth of cut for any single pass. When used in a router table upcut bits actually pull your material down.

Please note: Solid Carbide Router Bits are not eligible for product returns as user error that leads to breakages is not a variable we can control.
