The Freud 56-110 3/16-Inch Slot Three Wing Slotting Cutter is a carbide-tipped slotting cutter for routing clean, consistent slots and grooves in wood and composite materials. This is a slotting cutter designed for joinery, groove cutting, and T-molding work. Model Number: 56-110. If you need a 3/16 inch slot for spline joints, tongue and groove work, or similar routing tasks, this cutter is built for that job.

What makes this cutter worth a look is the combination of a 3/16 inch kerf, three cutting wings, and a maximum cut depth of 9/16 inch. In practical terms, that setup helps the cutter clear material efficiently and leave a more controlled slot than a simpler cutter design. The 2 inch overall diameter also gives it enough size to stay productive while still fitting the kind of routing work most woodworkers and cabinet installers actually do.

The carbide-tipped construction matters because slotting cutters take repeated side-load contact when you are running grooves along panel edges or cutting joinery in sheet goods. Carbide holds an edge longer than plain steel, especially in abrasive materials like plywood and MDF. That means less time fighting fuzzy edges and less time stopping to replace worn cutters in the middle of a project.

Freud rates this cutter for composition materials, plywood, hardwood, and softwood, so it is not a one-material accessory. If your work moves between solid stock and manufactured panels, that range is useful. It is a better fit for the shop or jobsite where one cutter needs to handle cabinet parts, trim details, and general joinery without being overly specialized.

This cutter is designed to be used with Freud slotting cutter arbors, specifically 60-100 for 1/4 inch shanks and 60-102 for 1/2 inch shanks, along with the 62-108 bearing. That compatibility piece is important because this is not a standalone router bit with an integrated shank. You are buying the cutter itself, then building the setup around the proper arbor and bearing for your router and application.

It can be used in both hand-held and table-mounted portable routers, which gives it real flexibility. A hand-held router makes sense for edge work and one-off cuts. A router table makes more sense when you need repeatable slot depth and better control over smaller parts. Either way, the 16,000 maximum RPM rating gives you a clear operating limit so you can match the cutter to the right router speed.

For woodworkers, cabinet shops, trim carpenters, and serious DIY users doing clean joinery, this cutter fills a very specific need. If you are building spline joints, routing grooves for inlays or T-molding, or cutting uniform slots in sheet goods, this is the kind of accessory that earns its keep fast. It is not a general-purpose bit, and that is the point. It is made for accurate slot work.
