Router bit DeWalt DT90009, 8 mm diameter, 22 mm cutting length

DeWalt DT90009 router bit with an 8 mm diameter and 22 mm cutting length is a precision woodworking cutter intended for edge profiling, slotting and trimming tasks. Designed for compatibility with routers and trimmers that accept an 8 mm shank and the specified cutting length, the bit delivers repeatable cuts for both professional and DIY applications. Its geometry and cutting length make it suitable for work on solid wood, plywood, MDF and similar panel materials when producing clean edges and consistent grooves.

Advantages

This DeWalt router bit provides accurate dimensional control thanks to its 8 mm diameter and 22 mm cutting length, enabling uniform depth and smoother finishes on successive passes. The tool is manufactured to meet industry tolerances for concentricity and balance, which reduces vibration and helps extend bearing and cutter life. Compatibility with common routers and trimmers that accept the specified shank size simplifies tool selection and changeover for workshop tasks.

Suitable for

• Edge profiling and chamfering on wooden workpieces
• Cutting grooves and slots in panels and solid timber
• Trimming laminate and edge banding
• Repeatable routing operations in cabinet and furniture making

Key specifications

• Cutter diameter: 8 mm
• Cutting length: 22 mm
• Intended material: solid wood, plywood, MDF, laminate
• Tool type: router/trimmer bit for edge work and slotting
• Typical use: edge profiling, slot cutting, trimming operations

How to use

Install the router bit in a compatible collet or chuck that accepts an 8 mm shank, making sure the bit is seated securely and the collet is tightened to the tool manufacturer's recommended torque. Set cutting depth according to the required profile and make test cuts on scrap material to verify depth and feed speed. Feed the router at a steady, controlled rate appropriate for the material; avoid forcing the cutter through too quickly to reduce chipping and router strain. For longer runs or deeper cuts, make multiple shallow passes rather than a single deep cut.

Usage recommendations

Use appropriate personal protective equipment (eye and ear protection, dust mask) and secure workpieces with clamps. Select feed speed and router rpm based on material density and cutter diameter to achieve the best surface finish. Regularly inspect and, if necessary, sharpen or replace the bit to maintain cut quality and extend service life.
