CMT 822.360.11B Slot Cutter by CMT is a three-wing carbide-tipped slotting blade engineered for routers and router tables where precision grooves and horizontal slots are essential to strong, repeatable joinery. With a 1-7/8 in. cutting diameter and a 15/64 in. teeth thickness, this slot cutter blade handles a wide range of woodworking tasks - cutting slots and grooves for splines, biscuits, T-molding, and tongue and groove joints. The 1/2 in. shank fits standard router collets, and the right-hand rotation design is compatible with conventional router setups. Paired with a CMT 824 series arbor (sold separately) fitted with a 22mm bearing, the cutter delivers a cutting depth of up to 12.7mm, giving you consistent, guided results across solid hardwood, plywood, MDF, and more.

Key Features

• Anti-Kickback Design - limits the bite each tooth can take per pass, reducing the risk of dangerous tool grab and making each cut more controlled and predictable for the operator.
• Micrograin Carbide Tips - a finer, denser carbide grain structure resists chipping and dulling longer than standard carbide, extending the working life of the blade between sharpenings.
• CMT Orange Shield Non-Stick PTFE Coating - the orange PTFE surface prevents pitch and resin from bonding to the blade body, reduces heat buildup during cutting, protects against corrosion, and keeps the bit performing like new over many uses.
• Three-Wing (3-Tooth) Configuration - three cutting edges distribute the workload evenly across the blade, producing cleaner slot walls and smoother groove surfaces with each pass.
• 1/2 in. Shank - the heavy-duty 1/2 in. shank provides greater rigidity and reduced vibration compared to smaller shanks, contributing to straighter, more accurate slots.
• Right-Hand Rotation - standard RH rotation is compatible with the vast majority of handheld routers, router tables, and CNC routing machines, making this blade a versatile fit for most workshops.
• 0.177 in. Plate Thickness - a precisely milled plate thickness ensures the slot width is consistent and repeatable, which is critical when fitting splines, biscuits, or T-molding that require a snug, gap-free fit.

Why This Product

• The anti-kickback geometry and micrograin carbide construction make this slot cutter a reliable choice for woodworkers who need clean, controlled groove cuts in demanding materials like hardwood, melamine, and MDF without sacrificing tool life.
• The PTFE non-stick coating directly addresses one of the most common frustrations with slotting blades - pitch and resin accumulation that slows cutting and scorches material - keeping the blade cleaner and cuts crisper across longer production runs.
• With a 15/64 in. kerf and compatibility with the CMT 824 series arbor system, this blade slots into a flexible, modular setup, allowing you to swap cutters and arbors to suit different groove widths and joinery applications without replacing the entire assembly.
• The 12.7mm maximum cutting depth and 1-7/8 in. diameter are sized to handle practical joinery depths for panel work, T-molding installation, and biscuit slot cutting, making this a purpose-matched blade for furniture, cabinet, and millwork applications.
