The CMT Grand Rabbeting Bit with Insert Knives is a high-performance 2-inch diameter rabbeting router bit engineered for precision woodworking in cabinet construction, panel making, and joinery applications. Featuring two replaceable hardwood-grade insert knives and a 1/2-inch shank, this bit delivers clean, accurate rabbet cuts across a wide range of materials including hardwood, softwood, plywood, MDF, chipboard, laminates, and plastics. When paired with the optional collar sets (791.705.00, 791.706.00, and 791.707.00), this CMT rabbeting bit produces 17 different rabbet sizes - giving woodworkers the flexibility to handle everything from standard dado joinery to under-sized plywood applications with a single tool.

Key Features

• 17 Different Rabbet Sizes: Compatible with optional collar sets 791.705.00, 791.706.00, and 791.707.00 - this means one bit replaces a full set of fixed-depth rabbeting bits, saving both cost and tool storage space.
• 2-Inch Cutting Diameter: The large 2-inch diameter provides a broad rabbeting reach, making this bit well suited for panel making and cabinet carcass work where wide, consistent rabbets are required.
• Two Replaceable Insert Knives: Reversible, two-sided insert knives extend the usable life of each knife and allow quick field replacement without discarding the entire bit body - reducing long-term tooling costs.
• 1-1/8-Inch Cutting Height: A generous 1 1/8-inch cutting height accommodates thicker workpieces and allows rabbeting of solid panels and cabinet-grade sheet goods in a single router table pass (for cuts within depth limits).
• 5/8-Inch Rabbet Depth (15mm): Produces a consistent 5/8-inch deep rabbet, which is a common depth specification for back panel and drawer bottom installations in furniture and cabinet work.
• HW (Hardwood-Grade) Carbide Material: Insert knives are manufactured from HW-grade material, providing durability and edge retention across hardwood, softwood, composite sheet goods, laminates, and plastics.
• 1/2-Inch Shank: The 1/2-inch shank offers a secure, low-vibration fit in full-size router tables, contributing to cleaner cuts and better surface finish on finished cabinet components.
• Right-Hand Rotation: Standard right-hand rotation is compatible with conventional router table setups, allowing straightforward integration into existing workshop configurations.
• Under-Sized Plywood Compatibility: The optional collar sets enable rabbet sizing calibrated for under-sized plywood, solving a common frustration when working with sheet goods that are thinner than their nominal dimensions.

Why This Product

• Woodworkers who need to cut multiple rabbet depths for cabinet backs, drawer bottoms, and panel joinery can achieve 17 different sizes from a single bit using the optional collar sets - eliminating the need to purchase and store multiple fixed-depth rabbeting bits.
• The replaceable insert knife design addresses a real cost concern: instead of replacing the entire bit when knives dull, users simply swap or flip the reversible knives, keeping the bit body in service far longer.
• The 2-inch cutting diameter and 1 1/8-inch cutting height make this bit capable of handling the wide rabbets common in furniture-grade cabinet construction, where smaller rabbeting bits fall short in single-pass capability.
• The ability to produce rabbets sized for under-sized plywood - a known challenge with standard rabbeting bits - makes this bit a practical choice for professional cabinetmakers working with nominal 1/2-inch or 3/4-inch plywood that measures slightly less than stated dimensions.
