CMT Rail and Stile Bit Set - a matched two-piece router bit set engineered for crafting the classic frame-and-panel joints used in cabinet door and fine furniture construction. With a 1 1/8 in. cutting diameter, a delicate 3/16 in. radius profile, and a 1/2 in. shank, this set mills complementary rail and stile profiles that join cleanly and precisely. The hardwood-grade carbide tips, industrial non-stick coating, and right-hand rotation make this set well-suited for router table work, handheld routing, and CNC applications across a wide range of wood species and engineered panel materials.

Key Features

• HW (Hardwood-Grade) Carbide Tips - resist wear during extended cutting sessions in solid hardwood, softwood, plywood, MDF, chipboard, laminates, melamine, and plastic, reducing the need for frequent bit changes.
• 3/16 in. Radius Profile - mills a refined, delicate decorative edge on frame components, producing a clean and consistent reveal that is characteristic of fine furniture and cabinetwork.
• Matched Rail and Stile Pair - both bits are designed to produce perfectly complementary profiles, so the rail and stile joints fit together without gaps or misalignment on the first pass.
• 1/2 in. Shank - provides a secure, vibration-dampening connection to the router collet, delivering smoother cuts and reducing chatter compared to smaller-shank alternatives.
• Right-Hand (RH) Rotation - conforms to the standard direction used by virtually all handheld routers, router tables, and CNC routing machines, ensuring broad compatibility.
• 2-Tooth Cutting Configuration - balances feed rate and surface finish, allowing clean material removal in hardwood and engineered panel products.
• Maximum Material Thickness of 23/32 in. - 7/8 in. - accommodates the most common door panel and frame stock thicknesses used in cabinet and furniture shop environments, with a minimum workpiece thickness of 5/8 in.
• CMT Orange Shield Non-Stick Coating - prevents the bit from overheating, reduces pitch and resin buildup on the cutting edges, and protects against corrosion, extending the working life of both bits.
• SinterHIP Industrial Chrome Carbide - carbide processed via Hot Isostatic Pressing prevents material failure under load and extends cutting life compared to standard-grade carbide.
• Tri-Metal Brazing (Silver-Copper-Silver) - reinforces the bond between the carbide tip and the bit body when cutting harder wood or composites, significantly reducing the chance of tip separation.

Why This Product

• The complementary matched-pair design means both the rail profile and the stile profile are engineered together, so builders can cut and assemble door frames without trial-and-error fitting or profile adjustment.
• The 3/16 in. radius is sized for a delicate, refined look - making this set the right choice for fine furniture and cabinetry where a subtle, elegant profile is preferred over a heavier ogee or cove.
• With a workable thickness range of 5/8 in. to 7/8 in., the set handles the full range of standard cabinet door frame stock without requiring a separate setup for thinner or thicker material within that window.
• SinterHIP carbide processing and Tri-Metal Brazing work together to keep the cutting edges intact through demanding production runs, making this set a practical choice for shops cutting large quantities of door frames in hardwood or composite materials.
