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. When used in a router table upcut bits actually pull your material down.
The upcut spiral direction ejects wood chips out of the way of the router bit point so it plunges easily with less chance of wandering, making it the perfect router bit for plunge cut mortises. It is fine for any hole or opening that will not be seen. For work requiring a finer finish consider a downcut spiral bit.
Infinity solid carbide spiral bits feature a helical design that is continuously in contact with the workpiece. This constant shearing action produces smoother, cleaner cuts than a straight router bit which repeatedly smacks the cutting edge against the wood. A spiral bit's geometry and top point also allow you to plunge it into your work like a drill.
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 strong body that reduces vibration and lasts up to 300% longer than regular router bits.
Please note: The recommended depth of cut for any single pass is half of the diameter of the tool. For example, if you are using a ¼″ diameter cutter you should only take a ⅛″ depth of cut for any single pass.
