Router Bit DeWalt DT90013 concave cutter R5 for woodworking

Concave router bit DeWalt DT90013 (R5) is a woodworking cutter designed to produce a consistent R5 radius concave profile in solid wood, plywood and common engineered wood materials. Compatible with handheld and table-mounted routers, this cutter is intended for shaping edges, creating decorative grooves and preparing profiles for joinery where a small rounded channel or bead is required. The cutter geometry and carbide tip deliver repeatable results when used at recommended router speeds and feed rates.

Advantages

The DeWalt concave cutter provides uniform R5 radius cuts with minimal tear-out on suitable woods and panels. Its carbide cutting edge maintains sharpness for prolonged use and allows accurate profiling on edges and surfaces. The shank and overall design ensure stable mounting in both hand and table routers, reducing vibration and improving finish quality. This bit's compact profile makes it suitable for detailed work in cabinetry, furniture framing and trim applications.

Suitable for

• Shaping and profiling wood edges and surfaces
• Creating decorative grooves and small channels
• Preparing rounded profiles for joinery and bead details
• Routing in solid wood, plywood and common engineered boards

Key specifications

• Profile type: concave cutter with R5 radius
• Intended use: handheld and table-mounted routers
• Material suitability: solid wood, plywood, engineered wood panels
• Cutting edge: carbide-tipped for extended durability
• Application: edge profiling, decorative grooves, joinery preparation

How to use

Mount the router bit securely in the router collet and ensure the shank is fully seated. Select an appropriate router speed and perform a test cut on scrap material to confirm feed rate and depth of cut. Make multiple light passes rather than a single deep cut to achieve a clean R5 concave profile and reduce strain on the cutter. Always route with the workpiece clamped or the router table fence set to maintain consistent contact and profile alignment.

Usage recommendations

Use carbide-friendly feed rates and moderate router speeds suitable for the workpiece material; reduce speed for smaller diameters or when working with laminated surfaces. Wear appropriate eye, hearing and dust protection and use push blocks or feather boards when routing small or narrow workpieces. Inspect the cutter regularly for wear and replace when cutting performance or finish quality declines.
