The CMT 800.506.11 3-Wing Slot Cutter Set is a professional-grade router bit set engineered for woodworkers who need versatile, precise slotting, grooving, and rabbeting performance in a single kit. Fitted with a 1/2 in. shank for secure, vibration-free seating in both handheld routers and router tables, this set produces clean, consistent slots ranging from 1/8 in. to 23/32 in. deep - making it equally well-suited for cutting biscuit joint slots, milling tongue and groove joints, and general dado or rabbet work across a wide range of wood-based materials.

Key Features

• 3-Wing Carbide-Tipped Cutters (HW Material) - three cutting edges per pass distribute cutting load evenly, resulting in smoother slot walls, reduced tearout, and longer tool life compared to single-edge designs.
• Adjustable Cutting Height from 1/8 in. to 23/32 in. - a wide depth range lets you dial in precise groove widths for biscuit joints, tongue and groove panels, and decorative grooves without swapping bit sets.
• 1/2 in. Shank - the larger shank diameter reduces flex and chatter during cuts, delivering straighter, more accurate slots especially when working in hardwoods and dense sheet goods.
• 1-7/8 in. Cutting Diameter - sized to efficiently clear material in a single pass, reducing the number of passes needed and speeding up production work on the router table or with a handheld router.
• Right-Hand (RH) Rotation - matches the standard rotation direction of all common router motors, ensuring immediate compatibility with your existing router setup without any special configuration.
• 12.70 mm Cutting Depth - provides sufficient depth capacity for standard biscuit slot geometry and typical tongue and groove joint profiles used in cabinet and furniture making.
• 3-3/16 in. Total Length - compact enough for use in close-clearance router table setups while still providing adequate arbor length for stacking cutters to achieve varied groove widths.

Why This Product

• The adjustable cutting height range of 1/8 in. to 23/32 in. gives woodworkers the flexibility to cut slots for multiple joint types - biscuit joints, tongue and groove, and rabbets - without purchasing separate bit sets for each profile.
• The 3-wing cutter geometry with hardened tungsten carbide (HW) tips means fewer passes, cleaner slot edges, and a longer service life when working with demanding materials such as hardwood, MDF, plywood, and laminates.
• The 1/2 in. shank provides a stable, chatter-free connection in both router tables and handheld routers, making this set a reliable choice for high-volume production as well as one-off custom joinery work.
• With a 1-7/8 in. cutter diameter and right-hand rotation, this set integrates immediately into standard router setups - no adapters, no special tooling, and no complicated configuration required before your first cut.
