Radius Beading Router Bit For Clean Bead Profiles

Radius beading router bit from Amana Tool cuts a quarter-round shape with fillets in a single pass, so woodworkers form consistent beads efficiently on edges or profiles. The bit is described as producing a quarter-round shape bounded by fillets, known as a bead, which focuses each pass on one clean, repeatable profile. The width of one fillet is set by the pilot bearing size, giving a fixed shoulder that keeps the bead alignment consistent along the workpiece. The other fillet is controlled by the depth of cut, allowing the user to adjust how the bead steps into the face or edge. This bit is part of the profiling router bits class, aligning it with common edge-shaping tasks in cabinet, furniture, or trim work where repeatable contours matter.

Key Router Bit Details That Drive Profiling Results

• The 3/4 inch diameter (D) cutting profile sweeps a broad quarter-round, allowing a noticeable bead detail in a single pass on suitable stock.
• The 1/8 inch radius (R) defines the bead curvature, so the resulting profile has a small, controlled round that reads cleanly on edges.
• The cutting height (B) of 3/8 inch provides enough vertical engagement to form the bead while keeping the profile focused on edge work.
• The 2 flute design distributes cutting across two edges, supporting smoother profiling passes along the grain when properly fed.
• The pilot bearing sets one fillet width, giving a fixed reference so the bead tracks consistently along the workpiece edge.
• The other fillet is controlled by depth of cut, letting installers adjust how deep the bead sits into the material face.

Shank, Length, And Setup Details For This Bit

This router bit has a 1/4 inch shank (d), so it fits collets designed for that shank size in compatible routers. The overall length (L) is 2 inches, providing enough projection from the collet for edge profiling while keeping the cutting portion compact for control. As a profiling router bit, this configuration supports common routing setups on benches or tables where repeatable edge passes are required. The relationship between shank size and overall length helps maintain stability as the quarter-round bead is routed along cabinet parts, trim, or similar components.

Where This Beading Router Bit Fits Best

This product is a 3/4 inch x 2 inch x 1/8 inch Radius beading router bit, 2-flute, with a 1/4 inch shank, fitting profiling workflows that call for a defined bead detail. As a profiling router bit in the Bits, Blades and Cutters category, it suits edge treatments on parts where a quarter-round bead is desired along a straight or gently curved edge. The bead produced is a quarter-round shape bounded by fillets, so it contributes a shaped transition between edge and face rather than a sharp corner. The 3/8 inch cutting height focuses the effect along the edge band, which suits cabinet doors, face frames, rails, or trim where a compact yet visible contour is useful.

Profile Options And Why The Details Matter

The bit is described as producing the bead in one pass, which reduces the number of setups needed to reach the final quarter-round profile on compatible stock. The width of one fillet is set by the pilot bearing size, so each run follows the workpiece edge consistently for uniform beads across multiple parts. The other fillet is controlled by the depth of cut, letting the user dial in how strong or subtle the step between bead and face appears. A beading bit can be transformed into a corner rounding bit by changing the bearing, and the reverse is also described, so the same cutter body supports either beading or corner rounding roles when the bearing arrangement is changed. This flexibility helps one bit body serve more than one profiling function within a routing setup.

Common Questions About This Beading Router Bit

Selecting This Router Bit For Bead Profiles

The 49596 router bit from Amana Tool pairs a 3/4 inch diameter with a 1/8 inch radius to deliver a defined quarter-round bead in one pass. With a 3/8 inch cutting height and 1/4 inch shank, it fits edge profiling setups that favor compact, controllable cutters. The ability to adjust one fillet by depth of cut, while the pilot bearing fixes the other, helps tailor the bead presence across different projects. For woodworking operations needing a beading or corner rounding role from a single cutter body, this profiling router bit aligns closely with that task.
