Table Edge Thumbnail Router Bit For Clean Profiles

Table edge thumbnail router bit from Amana Tool is a profiling router bit designed for cutting table top edges or for use with handrail side profile bits, so it serves both furniture and handrail work from one setup. The 2-9/16 inch diameter cutting profile sweeps a broad curve along the edge, which shapes a substantial, visible detail in a single pass. An 11/64 inch radius on the edge creates a refined eased contour, which softens sharp corners while defining a clear thumbnail profile. The 3/4 inch cutting height lets the bit cover a typical table top thickness, which reduces the need for multiple tools to finish one edge. A 1/2 inch shank connects the bit to the router, which provides a solid grip in common 1/2 inch collets. The overall 2-3/4 inch length keeps the bit compact, which supports stable routing on table edges.

Profiling Details That Support Edge Quality

• The 2-9/16 inch diameter (D) cutting profile spans a wide section of the edge, which allows the bit to form a full table top or handrail edge shape in a single, controlled pass.
• The 11/64 inch radius (R) at the working edge defines the thumbnail curve, which rounds the transition between faces and helps reduce sharpness on the finished edge.
• The 3/4 inch cutting height (B) matches common tabletop edge depths, which lets the bit reach the full profile height without leaving uncut flats on thicker edges.
• The 1/2 inch shank (d) engages robustly in a 1/2 inch router collet, which supports smoother cutting action during profiling of harder woods and longer edges.
• The 2-3/4 inch overall length (L) keeps the bit relatively short, which helps limit leverage on the router bearings during edge work and supports accurate tracking along the workpiece.
• The 2-flute cutting design uses a pair of cutting edges, which balances cutting forces around the bit and supports consistent surface finish along the routed edge.

Router Bit Geometry That Supports Smooth Setup

The Amana Tool router bit uses a 1/2 inch shank, which lets it seat securely in routers built for 1/2 inch tooling and supports stable alignment before routing. Its 2-9/16 inch diameter cutting circle defines how far the profile projects from the fence, which helps set the fence position to control how much material is removed in each pass. With a 3/4 inch cutting height, the bit engages enough edge depth to cover standard table top or handrail edge profiles, which simplifies height setting at the router table. The 11/64 inch radius at the profile edge governs the roundness of the thumbnail, which gives a predictable curve when matching existing work. The overall 2-3/4 inch length concentrates the cutting action near the collet, which supports smooth handling during profiling along straight or curved table edges.

Using This Router Bit On Table Tops And Rails

Where This Table Edge Bit Performs Best

This Amana Tool router bit is specified for cutting table top edges, so it suits projects where the edge profile is part of the finished design such as dining tables, desks, and worktops. The same bit is also specified for use with handrail side profile bits, so it plays a role in shaping the top or bottom edge of railing components when combined with complementary profiles. The 2-9/16 inch diameter allows the bit to sweep a generous arc on wide edges, which is useful on thicker tops where a small profile would look undersized. A 3/4 inch cutting height matches many edge depths on furniture tops and rail components, which keeps the working portion of the bit fully engaged across the profile. The 11/64 inch radius gives the edge a defined but not bulky curve, which fits applications where a cleaner, softer feel at the hand contact point is important.

Profile Details That Support Repeatable Results

The 49560 router bit uses a 2-flute design, which offers two cutting edges sharing the load so the bit tracks consistently around the edge during multiple passes. With a 1/2 inch shank, the bit seats deeply in routers designed for heavier profiling, which supports repeatable alignment after bit changes on recurring jobs. The 2-3/4 inch overall length keeps the cutting edges relatively close to the collet, which supports control and reduces deflection when following long edges or gentle curves on table tops and rails. Having an 11/64 inch radius clearly identified on the bit allows the same curve to be matched on additional parts, which helps maintain consistent edge geometry across a run of workpieces. The specified relationship between the 2-9/16 inch diameter and 3/4 inch cutting height defines a stable cutting geometry, which helps the bit create a repeatable thumbnail or bead effect along both furniture and handrail edges.

Common Buyer Questions About This Profiling Bit

Select This Router Bit For Edge Profiling Work

The Amana Tool 49560 router bit combines a 2-9/16 inch diameter, 11/64 inch radius, and 3/4 inch cutting height to form table top and handrail edges in one profiling setup. With a 1/2 inch shank and compact 2-3/4 inch overall length, it fits common 1/2 inch routers while keeping the cutting geometry close to the collet for controlled work. For shop projects that call for a consistent thumbnail or bead detail on tables or rails, this 2-flute profiling router bit provides a defined, repeatable profile based on its specified dimensions.
