CMT 822.016.11B Slot Cutter by CMT is a precision-engineered 2 1/8" diameter router bit designed to cut clean, accurate slots and grooves in a wide range of wood and composite materials. With a 1/8" cutting height and a 1/2" shank, this three-wing carbide-tipped slot cutter is ideal for biscuit joinery, spline routing, T-molding installation, and tongue-and-groove panel work. The anti-kickback body design, micrograin carbide tips, and CMT's signature orange non-stick PTFE coating make it a dependable choice for handheld router, router table, and CNC routing applications alike.

Key Features

• Anti-Kickback Design - limits the amount of material removed per pass, reducing the risk of sudden tool grab and giving the operator greater control during slotting operations.
• Micrograin Carbide Tips (HW Material) - ultra-fine carbide grain structure maintains a sharper cutting edge longer, resulting in cleaner slot walls and fewer tool changes across demanding production runs.
• Orange Non-Stick PTFE Coating - CMT's trademarked orange coating resists pitch and resin buildup, reduces friction-generated heat, and protects the bit body against corrosion, extending overall tool life.
• 3-Wing Cutter Geometry - three precisely ground carbide wings deliver balanced cutting forces and smooth, consistent 1/8" wide grooves in a single pass through solid hardwood, softwood, plywood, MDF, and more.
• 1/2" Shank - the full 1/2" shank provides maximum rigidity in the router collet, minimizing vibration and deflection for accurate, repeatable slot depth across every cut.
• Right-Hand Rotation (RH) - standard right-hand rotation is compatible with the vast majority of handheld routers, router tables, and CNC spindles without any special setup.
• 2 1/8" Diameter - the large-diameter blade reaches a 17.5mm cutting depth, making it well suited for routing T-molding channels and deep spline grooves in thicker panel stock.

Why This Product

• A single bit covers an almost infinite range of joinery tasks - biscuit slots, spline grooves, T-molding channels, and tongue-and-groove joints - reducing the need for multiple specialty cutters in the shop.
• The combination of anti-kickback geometry and micrograin carbide tips allows confident use in both solid hardwoods and engineered sheet goods like MDF, chipboard, melamine, and laminates without changing setups.
• The orange PTFE non-stick coating actively fights resin and pitch adhesion during extended use, meaning less cleaning downtime and more consistent cut quality over the life of the tool.
• With a 17.5mm cutting depth and a 1/8" kerf, this slot cutter is purpose-built for standard biscuit and T-molding dimensions, making it a precise, no-guesswork solution for panel joinery and furniture production.
