Dovetail router bit from Amana Tool is a 1/4 inch diameter, 2 flute router bit built for cabinet joinery workflows using dovetail jigs. The 1/4 inch shank matches common router collets, so it suits many shop and jobsite routers used for joinery. The 2 flute cutting design provides a balanced cut, which helps produce clean dovetail profiles when running along a jig template. The 7.5 degree angle is matched to dovetail layouts for the Incra and Omnijig systems, giving a consistent geometry between the bit and the jig fingers. A cutting height of 5/16 inch focuses the cut in a shallow band, which is useful for dovetail layouts that stay within typical cabinet stock thickness. The overall length of 2-1/2 inches leaves room for collet grip while exposing enough flute length to reach standard dovetail depths in guided cuts.
The 1/4 inch shank on this Amana Tool dovetail router bit seats into routers with a matching 1/4 inch collet, giving a straightforward setup for dovetail jig work. The 2-1/2 inch overall length leaves sufficient body outside the collet for depth adjustment when working with Incra or Omnijig setups. The 5/16 inch cutting height defines the active cutting band, so installers can set depth to keep the cut centered in cabinet joinery stock. The 7.5 degree cutting angle sets the wall shape of the dovetail, aligning with the jig fingers that guide the router movement across the workpiece.
This 1/4 inch x 2-1/2 inch dovetail router bit is specified for use with both the Omnijig and the Incra dovetail jig, so it fits directly into workflows built around those systems. The bit sits in the dovetail jig router carriage, and the 1/4 inch shank allows use in compact routers favored for guided joinery passes. When paired with these jigs, the 7.5 degree angle matches the guide pattern, so tails and pins follow the intended layout without changing the jig geometry. The 1/4 inch cutting diameter helps when forming finer joints in cabinet components, allowing narrow sockets and tails that align with detailed jig templates.
The 5/16 inch cutting height on this router bit limits the vertical engagement, which helps keep the routed section within the thickness range used in cabinet joinery. This focused cut band makes depth settings more predictable when repeating runs across multiple drawer sides or case parts. The 2 flute design balances the rotation as it travels through jig-guided paths, which supports a consistent feel and helps maintain the profile set by the Incra or Omnijig fingers. The 2-1/2 inch overall length provides room to position the bit so flutes clear the jig guide surfaces while the shank stays fully held in the collet, aiding stable operation. Combined, these details give installers a dovetail bit that works within the defined geometry and motion of the specified dovetail jigs.
This bit is used with both the Omnijig and the Incra dovetail jig, so it fits workflows built around those two guided dovetail systems.
The bit has a 1/4 inch diameter, 7.5 degree angle, and 5/16 inch cutting height, which together define the dovetail profile it forms in cabinet joinery.
The router bit has an overall length of 2-1/2 inches, leaving room for collet grip while reaching typical dovetail depths on jig-guided cuts.
The bit uses a 1/4 inch shank, so it mounts in routers equipped with a 1/4 inch collet commonly used for jig-based joinery.
The router bit is a 2 flute design, providing a balanced cutting action as it follows the Omnijig or Incra dovetail jig templates.
This dovetail router bit is manufactured by Amana Tool and identified by manufacturer part number 45820 for straightforward reordering.
This 1/4 inch x 2-1/2 inch Amana Tool dovetail router bit with 1/4 inch shank is purpose-matched to both the Incra and Omnijig dovetail jigs, aligning its 7.5 degree angle and 5/16 inch cutting height to their layouts. For installers and serious woodworkers standardizing on these systems, this bit provides a defined geometry and size that supports consistent cabinet joinery results across repeated projects.
