Product Description
CMT 800.526.11 3-Piece Tongue and Groove Cabinet Making Set by CMT is a complete router bit set engineered for precision cabinet making and fine woodworking joinery. Combining a flush trim bit with tongue and groove rail and stile bits, this 1/2 in. shank set gives woodworkers everything needed to cut accurate, tight-fitting joints in solid hardwood, softwood, plywood, MDF, and a range of sheet goods and laminates. Whether you are working at a router table, running a handheld router, or operating a CNC routing machine, this carbide-tipped set delivers clean, repeatable results across a wide variety of cabinet making and furniture applications.
Key Features
- 3-Piece Set Covering Flush Trim and Tongue and Groove Joinery - includes a Flush Trim Bit (806.628.11) and Tongue and Groove Rail and Stile Bits (855.507.11), giving you a coordinated combination of bits so you can complete cabinet door frames and panel fitting without switching between mismatched tools.
- 1/2 in. Shank Diameter - the larger shank size provides greater stability and reduced vibration compared to smaller shanks, resulting in smoother cuts and improved surface finish on cabinet components.
- Carbide-Tipped (TCT) Cutting Edges - tungsten carbide tips stay sharp through extended runs of hardwood and composite materials, reducing the frequency of sharpening or replacement and keeping production moving.
- SinterHIP Industrial Chrome Carbide - carbide processed via Hot Isostatic Pressing prevents material failure at the cutting edge and extends cutting life, so the bits maintain their precision geometry through demanding cabinet shop use.
- CMT Orange Shield Non-Stick Coating - prevents the bit from heating up, reduces pitch and resin buildup on the cutting surfaces, protects against corrosion, and extends overall tool life - meaning less cleaning time and longer intervals between bit changes.
- Tri-Metal Brazing (Silver-Copper-Silver) - the layered brazing process protects the carbide tip when cutting harder wood or composites and reduces the chance of failed welds, so the cutting edges stay securely bonded even under heavy feed pressure.
- Anti-Kickback Design - controls the depth of cut and minimizes kickback risk, improving operator safety during freehand routing and router table operations.
- Right-Hand (RH) Rotation - standard rotation is compatible with the vast majority of routers and CNC spindles, making this set a straightforward fit for most shop setups without any special tooling considerations.
- 2 Cutting Teeth per Bit - two-flute geometry balances chip clearance with surface quality, producing clean shoulders on tongue and groove profiles without excessive tearout in softwood or hardwood grain.
Why This Product
- One coordinated set for complete cabinet door joinery - instead of sourcing individual bits separately and hoping profiles align, the 800.526.11 packages flush trim and tongue and groove rail and stile profiles together so joints fit precisely the first time.
- Engineered for demanding materials beyond solid wood - the carbide-tipped, SinterHIP-processed cutting edges hold up in MDF, chipboard, melamine, laminates, and plastics, making this set practical for modern cabinet shops working with a broad material mix rather than solid lumber alone.
- Compatible with handheld routers, router tables, and CNC machines - the 1/2 in. shank and right-hand rotation make this set versatile across different production workflows, from small custom shops to larger CNC-assisted operations.
- Protective coatings and brazing technology reduce downtime - the Orange Shield non-stick coating and Tri-Metal brazing work together to keep bits cleaner, cooler, and more securely assembled during extended use, lowering the total cost of ownership over time.

Frequently Asked Questions
What router types are compatible with this set?
The CMT 800.526.11 set is compatible with handheld routers, router tables, and CNC routing machines. The 1/2 in. shank and standard right-hand rotation fit the vast majority of routers and CNC spindles used in woodworking and cabinet production environments.
What materials can these router bits cut?
The carbide-tipped cutting edges are suited for use in solid hardwood, softwood, plywood, MDF, chipboard, laminates, melamine, and plastic - making the set appropriate for both traditional solid-wood cabinet making and modern composite panel work.
What is the benefit of the Orange Shield non-stick coating on these bits?
The CMT Orange Shield non-stick coating prevents the bit from heating up during use, reduces pitch and resin buildup on the cutting surfaces, protects against corrosion, and extends tool life. In practical terms, this means less frequent cleaning and longer working life between sharpenings or bit replacements.
What is SinterHIP processing and why does it matter for carbide router bits?
SinterHIP stands for Hot Isostatic Pressing - a manufacturing process applied to the Industrial Chrome Carbide in these bits. This process reduces internal porosity and micro-defects in the carbide, which prevents material failure at the cutting edge and extends the overall cutting life of the bit through demanding hardwood and composite routing tasks.
