CMT 822.360.11A Slot Cutter by CMT is a precision three-wing routing blade engineered for creating clean, accurate slots and grooves in a wide range of woodworking and joinery applications. With a 1-7/8 in. cutting diameter and a 15/64 in. teeth thickness, this slot cutter blade is purpose-built for routing spline grooves, biscuit slots, T-molding channels, and tongue and groove joints. Designed for use with CMT 824 series arbors fitted with a 22mm (7/8 in.) diameter bearing, it delivers a cutting depth of up to 12.7mm (1/2 in.), making it a versatile choice for panel joinery, cabinet assembly, and furniture construction. The 1/4 in. shank and right-hand rotation make it compatible with handheld routers, router tables, and CNC routing machines.

Key Features

• CMT Orange Shield Non-Stick PTFE Coating - reduces pitch and resin buildup on the blade surface, prevents overheating during extended cuts, guards against corrosion, and extends overall tool life so you get more cuts between replacements.
• Micrograin Carbide Tips (HW Material) - industrial-grade hard metal tips resist wear and maintain a sharper cutting edge longer, producing cleaner slot walls in hardwood, softwood, plywood, MDF, laminates, and melamine.
• Anti-Kickback Design - limits the amount of material each tooth can remove per pass, reducing the risk of sudden tool grab and improving operator control and safety during freehand and table-mounted routing.
• Three-Wing Configuration (3 Teeth) - distributes cutting load evenly across three carbide tips, resulting in smoother slot finishes and reduced vibration compared to single- or two-wing designs.
• Right-Hand Rotation - standard RH rotation ensures compatibility with the vast majority of router spindles and arbor setups without the need for special tooling or adapters.
• 1/4 in. Shank - fits widely available router collets and arbors, making this blade easy to integrate into existing setups and reducing the need for adapters or specialty equipment.
• Blade-Only Format - sold as a standalone cutter that pairs with your choice of CMT 824 series arbors, giving you the flexibility to configure cutting depth and bearing diameter for your specific joint requirements.

Why This Product

• The 15/64 in. teeth thickness and 0.177 in. plate thickness create precise, consistently sized slots that seat splines, biscuits, and T-molding with minimal play - critical for strong, tight-fitting joinery.
• The anti-kickback geometry and micrograin carbide construction make this cutter well-suited for production environments where repeated passes through hardwood, MDF, chipboard, and laminated panels demand both safety and durability.
• Compatibility with CMT 824 series arbors fitted with a 7/8 in. bearing means cutting depth is adjustable up to 12.7mm (1/2 in.), giving you the versatility to handle multiple joint types - from biscuit slots to full tongue and groove profiles - with a single blade.
• The combination of PTFE non-stick coating and industrial carbide tips means less time cleaning resin from the blade and more consistent cut quality across materials like melamine, plastic, and plywood that are prone to gumming up standard tooling.
