The CMT Solid Carbide Dovetail Bit - 1/4 in. Diameter, 7.5 deg. Angle, 1/4 in. Shank is a precision-ground routing bit engineered for the classic dovetail joint, a hallmark of quality woodworking that appeals to both professionals and hobbyists. Built from solid carbide (HWM grade) rather than carbide-tipped steel, this bit delivers exceptional rigidity and edge retention when routing dovetail joints, sliding dovetails, and decorative joinery in hardwood, softwood, sheet goods, and more. With its 7.5 deg. undercut angle and compact 1/4 in. cutting diameter, it is specifically suited for use with the Incra jig system, giving woodworkers the accuracy needed to produce tight-fitting, hand-cut-style dovetail profiles directly on a router table or with a handheld router.

Key Features

• Solid Carbide (HWM) Construction - the entire bit body is machined from hard metal carbide rather than attaching a carbide tip to a steel shank, resulting in greater stiffness, reduced deflection, and longer service life in demanding production or fine woodworking environments.
• 7.5 deg. Dovetail Angle - the shallow undercut angle produces the precise trapezoidal profile required for tight-fitting dovetail joints and sliding dovetails, with the geometry optimized for Incra jig compatibility so setups are repeatable and accurate.
• 1/4 in. Cutting Diameter - the narrow profile allows routing of fine, delicate dovetail pins and tails in thinner stock where larger bits would remove too much material, making it ideal for box making and small drawer construction.
• 5/16 in. Cutting Height - the usable cutting length is sized to handle typical dovetail joint depths in solid hardwood and softwood without excessive bit exposure, which improves cutting stability and reduces chatter.
• 2-Flute (2-Tooth) Geometry - two cutting edges balance chip evacuation and surface finish, helping produce clean dovetail walls that require minimal sanding or paring after routing.
• Right-Hand (RH) Rotation - standard right-hand rotation is compatible with virtually all routers and router tables, so no special tooling or spindle adapters are required.
• 1/4 in. Shank - fits 1/4 in. router collets found on compact, trim, and full-size routers, giving this bit broad compatibility across router models commonly used for jig-based dovetail work.
• 2-1/2 in. Total Length - the overall length provides enough reach for standard dovetail jig setups while keeping the bit short enough to minimize vibration and maintain cut precision.

Why This Product

• Incra System Compatibility - this bit is specifically called out for use with the Incra jig system, meaning woodworkers who rely on Incra's precision indexing for repeatable dovetail layouts can trust the 7.5 deg. angle geometry to match the system's requirements without guesswork or custom angle grinding.
• Solid Carbide Over Carbide-Tipped - unlike standard carbide-tipped bits, the all-carbide body resists flexing at the cutting zone, which translates directly to cleaner, more consistent dovetail profiles, especially when routing across the grain in hardwoods like oak or maple.
• Right Size for Fine Joinery - with a 1/4 in. cutting diameter and 7.5 deg. angle, this bit occupies a niche suited for smaller-scale dovetails in box making, drawer fronts, and decorative woodworking where larger dovetail bits would be too aggressive.
• Compact Footprint, Broad Router Compatibility - the 1/4 in. shank and 2-1/2 in. total length mean this bit works with compact trim routers and full-size router tables alike, making it a practical choice for shops that use a single bit across multiple setups.
