The CMT 818.080.11 Solid Carbide Dovetail Bit is precision-engineered for cutting the classic trapezoidal dovetail profile, making it a reliable choice for woodworkers pursuing tight-fitting dovetail joints in hardwood, softwood, and sheet goods. With a 5/16 in. cutting diameter, a 9 deg. angle, and a 1/4 in. shank, this two-flute router bit is specifically designed for use with the Incra jig system and delivers the kind of crisp, clean cuts that define professional-quality joinery. Whether you are routing hand-cut-style sliding dovetails, assembling drawer boxes, or crafting decorative box joinery, this CMT solid carbide bit offers the durability and precision that both tradespeople and serious hobbyists depend on.

Key Features

• Solid carbide construction (HWM material grade) - delivers superior hardness and wear resistance compared to carbide-tipped designs, maintaining a sharp cutting edge longer through dense hardwoods and abrasive sheet materials.
• 9 deg. dovetail angle - produces the precise trapezoidal profile required for interlocking dovetail joints, ensuring a snug mechanical fit without excessive hand-fitting or trimming.
• 5/16 in. cutting diameter with 3/8 in. cutting height - sized specifically for fine dovetail work, allowing accurate slot and tail profiles in a single pass with consistent depth control.
• 1/4 in. shank - compatible with a wide range of handheld routers, router tables, and CNC machines fitted with a 1/4 in. collet, adding flexibility across different setups.
• 2-flute right-hand rotation design - balances chip evacuation and cutting speed, reducing heat buildup and leaving a cleaner finished surface in the joint profile.
• Designed for the Incra jig system - engineered to work in precise coordination with Incra dovetail jigs, enabling repeatable, accurately spaced dovetail layouts without manual layout work.
• 2-1/16 in. total length - provides enough reach for standard dovetail routing applications while keeping the bit rigid and reducing deflection during the cut.

Why This Product

• Solid carbide construction means this bit stays sharper longer through high-volume routing in hardwoods and abrasive materials, reducing the need for frequent bit changes or replacements.
• The 9 deg. angle is purpose-matched to Incra system jig templates, so woodworkers who already own an Incra jig get a perfectly compatible bit without guesswork or angle adjustments.
• At 5/16 in. diameter and a 3/8 in. cutting height, this bit handles both sliding dovetails and standard through-dovetail profiles, making it a versatile single tool for multiple joinery applications including drawer construction and box making.
• The compact 1/4 in. shank makes this bit accessible to users with lighter-duty routers and handheld units, not just large router table setups - broadening its usefulness across different shop configurations.
