A through-dovetail joint is visible from both sides of the corner — the classic look seen on drawer sides and box carcasses. A half-blind dovetail is concealed on one face, so the joint is hidden from the front — the standard used for drawer fronts on fine furniture. Leigh jigs like the D4R Pro cut both styles.

Yes. Router dovetail jigs guide the router bit at the correct angle and spacing automatically, making it possible for a beginner to cut consistent dovetails on the first attempt. The Leigh RTJ400 is specifically designed for router table use, which adds stability for new users. Always make test cuts in scrap wood before working on project pieces.

The Leigh D4R Pro accepts both 1/2-inch and 8mm shank bits. Infinity Tools offers a dedicated 16-piece 1/2" & 8mm shank dovetail & straight bit set matched to that jig for immediate compatibility.

The Infinity Tools Tapered Dovetail Spline System is used to join two boards — typically at the corner of a box or case — using a wedge-shaped spline that locks mechanically into routed slots. The tapered geometry allows the joint to be assembled dry (without glue) while remaining extremely rigid.

Variable spacing means the dovetail jig allows you to adjust the position and number of tails, rather than being locked to a fixed-interval template. The Leigh D4R Pro supports variable spacing, which gives a more traditional, hand-cut appearance compared to the uniform spacing produced by many fixed-template jigs.

Most dovetail jigs, including the Leigh D4R Pro, are used with a handheld router guided over the jig. The Leigh Router Table Dovetail Jig is specifically designed for a router table, where the workpiece is moved over a stationary bit — a preferred approach for production work or users who find handheld routing less comfortable.

Infinity Tools manufactures dovetail bits in 1/4", 1/2", and 8mm shank sizes to match a wide range of jigs and routers. The 1/2" shank dovetail router bits are the most versatile for full-size routers and provide the best rigidity and chatter resistance during cutting.

The Infinity Tools 8-Piece Dovetail & Box Joint Router Bit Set includes bits for both joint styles, making it easy to switch between box joints and dovetails with the same jig setup.
