Amana Tool 45850 dovetail bit is a carbide tipped router bit designed for routing dovetail slots, giving cabinet and woodworking projects a consistent mechanical joint profile. The 14 degree dovetail angle shapes a traditional dovetail form that locks into matching hardware or mating parts, which matters when repeatable engagement is needed across multiple pieces. A 1/2 inch diameter cutting profile balances material removal and control, so the bit tracks predictably along the template path in cabinet joinery work. The bit uses a 1/4 inch shank, fitting routers that accept this common shank size and allowing straightforward setup in many handheld and table-mounted routers. An upper ball-bearing guide mounted on the shank rides directly on the template surface, so the cutting edge follows the pattern instead of relying on fences or manual tracking, which helps hold alignment over longer runs.
This carbide tipped dovetail bit is built for template and pattern routing where the bearing follows a guide surface. The manufacturer specifies that the template must be mounted between the workpiece and the router, which defines how the routing stack is arranged in use. With a handheld router, the template sits on top of the workpiece, so the bearing contacts the template while the cutter forms the dovetail slot below, aligning the slot exactly to the pattern. With a table-mounted router, the template is placed underneath the workpiece, so the bearing runs against the hidden template as the workpiece is guided over the table, keeping the slot aligned to the same reference pattern from below.
This Amana Tool router bit is categorized under bits, blades and cutters for cabinet joinery, so its design supports tasks common in cabinet shops and woodworking setups. The 14 degree dovetail geometry shapes slots that can engage matching dovetail hardware or sliding components in furniture and cabinet assemblies, which contributes to joints that resist pullout in normal service. When routing dovetail slots that follow a template, the shank-mounted bearing maintains a fixed relationship between the cutting edge and the pattern, which is valuable when repeating stopped or curved slots across multiple identical parts. In handheld routing, placing the template on top of the workpiece means the operator references a visible guide surface, allowing the bearing to trace complex layouts directly on the pattern for consistent slot positioning.
The upper ball-bearing guide mounted on the shank is the key feature for pattern routing with this dovetail bit, because it physically contacts the template instead of relying on visual alignment. By requiring the template between the router and workpiece, the bit locks the cutting path to the template thickness and shape, which helps maintain uniform slot depth and position across identical parts. On a router table, locating the template underneath the workpiece keeps the reference pattern flat against the table surface while the workpiece rides above, supporting stable feed during production-style runs. The carbide tipped construction of the cutting edges allows the bit to maintain the 14 degree profile during extended use on suitable materials, which keeps dovetail slot geometry consistent from the first part in a batch to the last.
The Amana Tool 45850 is a carbide tipped dovetail router bit with a shank-mounted ball-bearing guide, which is used for routing dovetail slots that follow a template or pattern.
The Amana Tool 45850 cuts a 14 degree dovetail profile, which shapes a traditional dovetail slot used for cabinet joinery and similar woodworking applications requiring a defined dovetail geometry.
The Amana Tool 45850 uses an upper ball-bearing guide on the shank that rides directly on a template, so the cutting edge follows the template pattern for consistent dovetail slot paths.
With a handheld router, the Amana Tool 45850 is used with the template on top of the workpiece, letting the bearing ride the template while the bit cuts the dovetail slot below.
With a table-mounted router, the Amana Tool 45850 is used with the template underneath the workpiece, so the bearing tracks the hidden pattern from below during dovetail slot routing.
The Amana Tool 45850 has a 1/4 inch shank, so it installs in routers that accept this shank size, supporting straightforward bit changes between different cabinet joinery operations.
The Amana Tool 45850 dovetail bit pairs a 14 degree profile with a 1/2 inch cutting diameter and 1/4 inch shank, giving a defined geometry for cabinet joinery tasks. The shank-mounted ball-bearing guide is engineered for template and pattern routing with the template positioned between router and workpiece, so dovetail slots follow the pattern on both handheld and table-mounted setups. For shops that rely on guided routing for repeatable dovetail slots, this bit offers a clearly defined cutting profile and a dedicated template-following system for cabinet and woodworking projects.
