Often called a compression bit - get a sharp clean edge on both sides of your piece when set correctly. Ideal for laminates, plywood, and hardwoods.

Round Tip Spirals

2D / 3D Carving CNC Bits

Flush Trim Spirals

Because these bits have a bearing mounted at the tip we recommend using them with a router table setup. Once you set the height so the bearing runs along the template edge - you'll have a clear view of the template while the workpiece sits on the table. Spiral bits will offer a cleaner cut - but are more expensive than their straight bit equivalents.

Template Spiral BIt

Used for handheld template routing instead of router table setup. Spiral bits will offer a cleaner cut - but are more expensive than their straight bit equivalents.

Combination Trim Spiral Bit

Can be used as template bit or flush trim - just no plunging. Spiral bits will offer a cleaner cut - but are more expensive than their straight bit equivalents.
