The CMT 818.191.11 Dovetail Bit is a precision-ground, right-hand rotation router bit designed to cut the classic trapezoidal dovetail profile used in fine woodworking joinery. With a 14 deg. cutting angle, a 3/4" diameter, and a 1/4" shank, this 2-flute carbide bit is built for use in handheld routers, router tables, and CNC routing machines. Whether you are crafting interlocking drawer boxes, building decorative cases, or routing sliding dovetail joints in solid hardwood or sheet goods, this bit delivers the clean, smooth profile that defines quality craftsmanship. CMT's engineering puts a focus on reducing heat buildup and extending cutting life, making this bit a dependable choice for both professional cabinetmakers and dedicated woodworking enthusiasts.

Key Features

• 14 deg. dovetail cutting angle - produces the precise trapezoidal profile required for tight-fitting, mechanically interlocking dovetail joints in both hand-routing and jig-guided applications.
• 3/4" cutting diameter with 7/8" cutting height - covers a generous cross-section in a single pass, reducing the number of setups needed for wider dovetail slots and sliding joints.
• 1/4" shank - fits standard 1/4" collets found on a wide range of handheld routers and router tables, making this bit broadly compatible without adapters.
• 2-flute HW (carbide) construction - two carbide cutting edges share the workload evenly, resulting in a cleaner cut surface and a longer service life compared to single-flute designs.
• Right-hand (RH) rotation - conforms to the standard rotation direction of virtually all routers, so the bit can be used safely and predictably without any special setup.
• CMT Orange Shield non-stick coating - prevents pitch and resin from bonding to the bit body, reducing heat buildup during extended cuts and protecting against corrosion to keep the bit performing longer.
• 2 3/8" total length - provides sufficient clearance above the workpiece for use in router table setups equipped with a fence, enabling difficult chamfer angles and sliding dovetail cuts with consistent depth control.

Why This Product

• The 14 deg. angle is a widely used standard for dovetail joinery, meaning this bit works directly with the most common dovetail jigs and templates without requiring angle adjustments or custom setup.
• Running a straight bit for the first pass and then following with this dovetail bit reduces stress on the cutting edges and produces a cleaner finished profile - a technique that extends the life of the bit and improves cut quality in hardwoods and dense sheet materials.
• The combination of a 3/4" diameter and a 7/8" cutting height makes this bit well-suited for drawer construction and box making, where both the pin and the socket of the joint need to be routed cleanly and completely in one tool setup.
• CMT's non-stick orange coating addresses one of the most common problems with dovetail routing - resin and pitch accumulation that causes burning and rough surfaces - keeping the bit cutting smoothly across hardwood, softwood, plywood, MDF, and laminates.
