Ultra-Shear Spiral Dovetail Router Bits

Smooth & Chatter-Free Dovetail Precision

Ultra-Shear Solid Carbide Spiral Dovetail Bits solve the most common challenge in joinery: the "one-pass" requirement. Unlike standard bits, these utilize spiral cutting geometry to ensure the bit is constantly engaged with the wood, eliminating the interrupted cuts and heavy vibration that lead to chatter. Crafted from micro-grain carbide with ultra-fine grinding, they deliver the sharpest and cleanest dovetail joints available.

Includes Essential Angles for Diverse Joinery

  • 8° Angle: .825" cut length for a classic, subtle dovetail appearance.

  • 10° Angle: .780" cut length, providing a balanced look for various furniture styles.

  • 14° Angle: .563" cut length, offering a steep, traditional aesthetic for smaller projects.

  • All bits feature a 1/2" shank and a 1/2" diameter at the widest point for maximum stability.

This range ensures you have the perfect mechanical lock and visual appeal for everything from heavy-duty drawers to delicate jewelry boxes.

Ideal for Flawless Joinery

Dovetail joints are the hallmark of fine craftsmanship, but they can be punishing on tools. Because the widest part of the bit is at the tip, traditional bits often struggle with heat and chip evacuation. The spiral up-cut design of these Ultra-Shear bits pulls shavings up and out of the joint, turning what would normally be wood dust into "fluff" and leaving behind a smooth surface that fits perfectly every time.

Versatility Beyond CNC

While CNC applications are a primary use for precise automated joinery, these bits shine in hand-held routers with dovetail jigs or on router tables and horizontal routing systems. They are ideal for creating sliding dovetails, drawer joinery, and decorative inlaid accents. Whether you are using a dovetail jig or a horizontal mortiser, the continuous spiral engagement provides a level of control and safety that straight-edged bits simply can't match.

Made in the USA

All Ultra-Shear Solid Carbide bits are manufactured in Strongsville, Ohio facility. We use high-quality carbide blanks, ultra-fine grinding wheels, and advanced CNC grinding equipment to produce great American-made router bits.
