3-Wing Slot Cutter Bit For Groove Joinery

3-wing slot cutter bit 3/32 kerf from Amana Tool is a router bit designed to cut consistent grooves for cabinet and woodworking joinery. The 3-wing slotting cutter head grooves edges for T-molding, splines, or biscuits, so one bit handles several common edge-joining tasks in the shop. The bit routs tongue and groove joinery, allowing you to form matching profiles for strong panel and frame construction where accurate alignment is important. Its 1-7/8 inch outside diameter controls the cutting circle size, which helps manage cut feel and contact area when routing edges. Overall length of 2-3/8 inches supports reach through typical stock thicknesses used in cabinet joinery while still fitting comfortably in most router setups. As a router bit in the Bits, Blades and Cutters category for Cabinet Joinery, it is built specifically for woodworking joinery operations rather than general-purpose routing.

Key Slot Cutter Details For Cabinet Joinery

• The 3-wing slot cutter head cuts a groove edge in a single pass, which helps produce an even kerf for T-molding, spline, or biscuit work without repeated cuts.
• A 3/32 inch kerf width sets a consistent groove size, so matching parts for tongue and groove joinery fit to the same cut dimension across a run.
• The 1-7/8 inch outside diameter defines the cutting circle, which influences how the bit engages the workpiece edge during cabinet joinery routing.
• An overall length of 2-3/8 inches provides working reach for typical cabinet stock thickness, while allowing stable chucking in compatible router collets.
• The 1/4 inch shank interfaces with routers that accept this shank size, supporting use in both handheld and table mounted router setups on the same jobs.
• Use with all handheld and table mounted routers ties this bit to common shop routing equipment, so the same cutter serves both portable and stationary workflows.

Installation And Router Setup Details That Matter

This 1/4 inch shank router bit is designed for routers that accept a 1/4 inch shank, so it aligns with a widely used collet size in cabinet and woodworking shops. Use with all handheld and table mounted routers means the bit can be set up in a portable router for on-site work or in a table mounted router for controlled groove runs in the shop. The 1-7/8 inch outside diameter affects how much of the cutter projects beyond the router base or table insert, which matters when setting cutting depth and guarding exposed edges. With an overall length of 2-3/8 inches, the bit provides enough projection above the collet to cut groove edges while leaving sufficient shank length held in the router for stable operation.

Using This Slot Cutter Bit In Cabinet Joinery

Where This 3-Wing Slot Cutter Performs Best

This Amana Tool router bit is positioned in the Cabinet Joinery class, so it is oriented toward furniture and cabinet construction work instead of rough carpentry. The 3-wing slotting cutter is specified to groove edges for T-molding, splines, or biscuits, which places it directly in edge-joining and trim-groove operations on panels and case parts. When you rout tongue and groove joinery with this bit, it supports assembling cabinet panels or frames with interlocking profiles that align surfaces during glue-up. Using it in both handheld and table mounted routers means the same cutter can handle cabinet sides on a router table and then move to jobsite tasks where a handheld router is more practical.

Why These Bit Dimensions Support Repeatable Grooves

The 3/32 inch kerf dimension defines the groove width this cutter produces, so each pass creates a slot sized for T-molding, splines, or biscuits that are matched to this cut width. This consistent kerf helps keep mating joinery parts uniform across multiple workpieces in a run. The 1-7/8 inch outside diameter establishes the radial sweep of the cutting edges, which influences chip load and contact area as you feed cabinet parts past the cutter. Together with the 2-3/8 inch overall length, these dimensions balance reach and control, allowing you to expose only the cutting portion needed while keeping most of the shank gripped in the 1/4 inch collet. Because the bit is specified for use with all handheld and table mounted routers, these proportions are set to work within the depth and fence adjustments commonly available on that equipment.
