3 Wing Slot Cutter Bit For Clean Cabinet Grooves

3 wing slot cutter bit from Amana Tool is a router bit designed for cutting grooves used in cabinet joinery. The bit is specified for grooving edges for T-molding, splines, or biscuits, so it supports several standard woodworking joint methods on a single tool. Its 3/16 inch kerf establishes a consistent slot width, which helps parts register accurately when fitting T-molding or inserting spline stock. With an overall length of 2-3/8 inches and an outside diameter of 1-7/8 inches, the cutter provides reach and cutting diameter suited to typical cabinet components and panel edges. The 1/4 inch shank interfaces with routers that accept that shank size, which allows this bit to be used in many common shop and jobsite routers. Amana Tool branding identifies it as part of a well-defined router bit line aimed at cabinet joinery tasks.

Key Slot Cutter Details For Cabinet Joinery

• The 3/16 inch kerf dimension controls slot width, so T-molding, splines, or biscuits seat consistently and align parts predictably in cabinet assemblies.
• The 3 wing cutter design distributes cutting around the circumference, which promotes smoother groove walls that help mating parts slide in without excess resistance.
• The 1-7/8 inch outside diameter sets the cutting circle size, allowing grooves to be cut with enough circumference to stay stable against the workpiece during routing.
• The 2-3/8 inch overall length provides working reach beyond the collet, which is useful when routing along panel edges or cabinet parts with some thickness.
• The 1/4 inch shank specification matches routers built for that shank size, simplifying setup on handheld or table mounted machines already configured for 1/4 inch tooling.
• Use with all handheld and table mounted routers expands where the bit can be put to work, so the same cutter handles bench work and installed cabinetry adjustments.

Slot Cutter Fit, Shank Size, And Router Setup

The 1/4 inch shank on this router bit defines how it seats in a router collet, so it is suited to routers designed for 1/4 inch tooling commonly found in cabinet shops. Its use with all handheld and table mounted routers means the same bit can be run in a portable router on site or in a stationary router table in the shop, which keeps the cutting geometry consistent across different setups. The 1-7/8 inch outside diameter and 2-3/8 inch length give the cutter a defined profile that helps maintain a steady cut along cabinet edges and panel faces, so groove depth and position remain uniform from start to finish on a run of parts.

Using This Amana Tool Bit In Cabinet Workflows

Where This Slot Cutter Bit Proves Most Useful

This Amana Tool router bit is identified in the Cabinet Joinery class, so it is oriented toward tasks like building and adjusting cabinets, furniture casework, and similar wood assemblies. Grooving edges for T-molding leverages the 3/16 inch kerf to cut a repeatable channel so plastic or wood T-molding locks into place along panels, display fixtures, or cabinet edges. Cutting slots for splines uses the same kerf dimension to create alignment joints along panel seams or mitered corners, which helps keep faces flush when parts are glued together. When used for biscuits, the specified kerf width cuts a slot that accepts biscuit connectors, supporting panel edge joining and carcass assembly. The router bit fits into handheld routers for on-site modifications, so cabinet edges and panels already installed can be grooved without moving large pieces back to a shop. In a table mounted router, the same bit supports production-style cabinet joinery, letting parts be passed across the cutter for repeatable groove placement.

How Verified Details Support Repeatable Groove Results

The 3/16 inch kerf rating defines the slot thickness, so every pass produces grooves sized for T-molding, splines, or biscuits without repeatedly gauging the cut. The 3 wing cutter design spaces cutting edges evenly around the bit, which stabilizes the cut as material contacts multiple wings in rotation, reducing deflection that could shift groove position. With a 1-7/8 inch outside diameter, the bit engages enough material per pass to maintain a clear cutting path while staying compact for edge work and cabinet parts. The 2-3/8 inch overall length provides a consistent distance from shank to cutting wings, which helps when setting depth stops or fence positions on router tables and handheld bases. Because the bit is specified for use with all handheld and table mounted routers, operators can keep the same joinery geometry whether working at a bench, at a table, or directly on installed cabinetry. The Router Bits product class and Amana Tool manufacturer designation place this cutter within a specialized line of joinery tooling, giving cabinetmakers a dedicated option for groove-based joints.
