The CMT 822.364.11A Slot Cutter is a three-wing carbide-tipped routing blade engineered for cutting precise horizontal slots, grooves, and joinery profiles in a wide range of wood and composite materials. With a 1-7/8 in. cutting diameter, a 1/4 in. teeth thickness, and a 1/4 in. shank, this slot cutter blade is purpose-built for use with compatible slot cutter arbors (CMT 824 series) to deliver clean, repeatable results in handheld routers, router tables, and CNC routing machines. Whether you are routing spline grooves, biscuit slots, T-molding channels, or tongue-and-groove joints, this CMT blade brings professional-grade precision and longevity to every pass.

Key Features

• CMT Orange Shield Non-Stick PTFE Coating - The trademark orange coating prevents pitch and resin buildup on the blade, reduces friction-generated heat during cutting, and protects against corrosion, all of which extend the working life of the cutter and reduce maintenance time between uses.
• Micrograin Carbide Tips (HW Material Grade) - Industrial-grade micrograin carbide maintains a sharper, more durable cutting edge longer than standard carbide, which means fewer sharpenings, cleaner slot walls, and consistent performance across hardwoods, softwoods, plywood, MDF, laminates, and plastics.
• Anti-Kickback Design - Built-in anti-kickback geometry limits the bite per tooth, reducing the risk of sudden, dangerous tool reactions during routing - a critical safety feature when working at high router speeds or feeding stock through a router table.
• Three-Wing Configuration (3 Teeth) - The three-tooth design distributes cutting load evenly across the blade, producing a smoother slot finish and reducing vibration compared to single- or two-wing alternatives, which translates to cleaner joints and less sanding or fitting work.
• 1/4 in. Shank Compatibility - Designed for routers equipped with 1/4 in. collets, making this cutter accessible for a wide range of compact and full-size routers commonly found in woodworking shops and on jobsites.
• 0.177 in. Plate Thickness - The precise plate thickness controls the exact width of the slot produced, ensuring a consistent, tight-fitting groove for splines, biscuits, or T-molding profiles without secondary cleanup passes.
• Right-Hand Rotation - Matches the standard rotation direction of virtually all routers, ensuring safe and correct tool engagement without special setup or spindle reversals.
• 12.7mm Cutting Depth - Provides up to 1/2 in. of usable cutting depth per pass when used with a compatible 22mm (7/8 in.) bearing arbor, suitable for most panel joinery and groove-cutting applications.

Why This Product

• The anti-kickback design and micrograin carbide tips make this slot cutter a reliable choice for high-volume woodworking operations where both safety and tool longevity are priorities - reducing interruptions and replacement costs over time.
• The nearly infinite range of applications - from biscuit joinery to T-molding channels to spline grooves - means this single blade can serve across multiple project types, reducing the number of specialty bits needed in a router bit collection.
• The CMT Orange Shield PTFE non-stick coating actively reduces heat and resin buildup during cutting, making this cutter well suited for demanding materials like melamine, chipboard, and plastic where pitch accumulation is a common problem with uncoated blades.
• With a 1/4 in. shank and right-hand rotation, this slot cutter fits directly into standard router setups without adapters or special tooling, making it a practical, drop-in addition to any woodworking or cabinetmaking workflow.
