CMT 823.340.11B Slot Cutter by CMT is a precision-engineered 1 7/8" diameter slot cutter designed for routing grooves, rabbets, spline slots, and panel joinery connections in wood and wood-based materials. With a 3-tooth carbide-tipped design, anti-kickback geometry, and a PTFE non-stick coating, this bit delivers clean, consistent cuts in solid hardwood, plywood, MDF, and more - making it a versatile choice for cabinetry, furniture assembly, and panel connector installation.

Key Features

• 3-Tooth Carbide-Tipped Cutters (HW Material): Hard metal carbide tips maintain a sharp cutting edge through dense hardwoods and engineered panels, reducing the need for frequent bit changes and extending overall service life.
• Orange PTFE Non-Stick Coating: The PTFE surface coating reduces friction, prevents pitch and resin buildup on the cutter body, and protects against corrosion - keeping the bit running cooler and cleaner over extended use.
• Anti-Kickback Design: Limits the depth of cut on each tooth to control feed rate and reduce the risk of dangerous kickback during routing, improving safety for both handheld and table-mounted router applications.
• 22mm (7/8") Bearing Included: A precision guide bearing is included in the package, providing a cutting depth of 12.7mm (1/2") for accurate, repeatable slot positioning along a workpiece edge without additional setup tools.
• Right-Hand Rotation: Compatible with standard router spindles, making this slot cutter a direct drop-in for handheld routers and router tables without any special tooling or adapter requirements.
• 1/2" Shank Diameter: The 1/2" shank provides maximum shank contact in standard router collets, reducing vibration and deflection during cutting for cleaner slot edges and improved dimensional accuracy.
• Versatile Joinery Capability: Cuts grooves, rabbets, T-slots, and spline channels in a single setup, making this bit suitable for a wide range of woodworking and panel fabrication tasks.

Why This Product

• The included 7/8" guide bearing locks in a precise 1/2" cutting depth right out of the box - no separate bearing purchase or depth-setting guesswork required, which speeds up setup and keeps cuts consistent across multiple workpieces.
• With 3 carbide-tipped teeth and an anti-kickback profile, this slot cutter handles demanding materials like solid hardwood and MDF safely, making it a reliable choice for production runs where both accuracy and operator safety matter.
• The 5/32" kerf width and 0.081" plate thickness make this cutter well-matched for routing spline grooves and panel connector slots where tight tolerances are critical to a strong, flush joint.
• The PTFE coating and durable HW carbide construction work together to reduce heat buildup and resin adhesion during long cutting sessions, helping maintain bit performance and surface finish quality over time.
