Master Octagonal Joinery and Crisp Edges with the Freud 22-1/2 Degree Chamfer Bit

Unlock the secret to constructing perfect octagons with the Freud 40-101 1-1/4" Diameter 22-1/2 Degree Chamfer Router Bit. While standard chamfer bits are great for easing edges, this specific 22.5-degree profile serves a critical function in advanced joinery. By routing this precise angle onto the mating edges of your stock, you can create seamless 45-degree joints that come together to form flawless 8-sided columns, planters, and decorative multi-sided boxes. It is the essential tool for woodworkers looking to expand their geometric construction capabilities beyond simple squares and rectangles.

Engineered for precision and longevity, the 40-101 is crafted with Freud’s exclusive TiCo™ Hi-Density Carbide. This premium micrograin formula ensures a razor-sharp cutting edge that withstands the rigors of cutting hardwood, softwood, plywood, and abrasive composites without dulling prematurely. The bit is encased in Freud’s signature Red Perma-SHIELD® Non-Stick Coating, which minimizes friction, prevents heat buildup, and resists pitch adhesion. With a heavy-duty 1/2" shank and a computer-balanced design, this bit delivers smooth, chatter-free performance in both hand-held and table-mounted routers.

Key Features

  • Octagonal Joinery: Precision-ground 22-1/2° angle allows for the construction of perfect 8-sided projects.
  • Adjustable Profile: Change the chamfer size easily by adjusting the bit height or fence depth.
  • TiCo™ Hi-Density Carbide: Proprietary blend delivers a superior finish and extended cutting life.
  • Perma-SHIELD® Coating: Non-stick red coating protects against heat, corrosion, and resin buildup.
  • Versatile Application: Ideal for edge easing, decorative bevels, and coopered joinery.
  • Broad Compatibility: Safe for use on CNC, hand-held, and table-mounted routers.
  • Precision Balanced: Computer-balanced to eliminate vibration for a professional-grade finish.

Pro-Tip: The math behind the joinery is simple: two pieces routed at 22.5 degrees create a 45-degree corner when joined. Since an octagon (8-sided shape) is made of eight 45-degree corners, this bit is the exact tool required for the job. Ensure your stock is milled perfectly square before routing to guarantee tight, gap-free joints.
