Router Cutter DeWalt DT90004, 8 mm shank, 20 mm working length

DeWalt DT90004 router cutter with an 8 mm shank and 20 mm working length is designed for edge profiling, trimming and routing tasks on wood, MDF and comparable materials. The solid 8 mm shank fits compatible routers and trimmers, while the 20 mm cutting length allows deeper profile cuts and consistent results on edges and surfaces. The cutter's construction supports repeated use in carpentry and joinery where accurate, repeatable routing is needed.

Advantages

The 8 mm solid shank provides stable mounting in compatible routers and trimmers, reducing vibration and improving cut accuracy. A 20 mm working length enables deeper engagement with the workpiece for pronounced profiles and multiple-pass trimming. The cutter is manufactured to maintain consistent geometry for repeatable edge profiles and clean cuts on wood-based materials. Its dimensions make it suitable for both handheld routing and table-mounted operations where precision is required.

Suitable for

• Edge profiling and decorative moulding on solid wood and engineered boards
• Trimming and finishing of veneered panels and MDF
• Routing grooves and rebates for joinery tasks
• Portable router or trimmer work where an 8 mm shank is required

Key specifications

• Shank diameter: 8 mm
• Working (cutting) length: 20 mm
• Intended materials: wood, MDF, veneered boards and similar wood-based materials
• Use: edge profiling, trimming, routing and groove cutting

How to use

Secure the cutter in a compatible router or trimmer with an 8 mm collet, ensuring the shank is fully seated and the collet tightened to the manufacturer's torque recommendations. Set the router speed and depth of cut according to the material and the required profile depth; for harder woods, reduce the feed rate and use multiple shallow passes rather than a single deep cut. Support the workpiece firmly and use appropriate guides or fences for straight profiles. Inspect the cutter before use for any damage or wear and replace if cutting performance degrades.

Usage recommendations

Use appropriate personal protective equipment, including eye and hearing protection, and follow router manufacturer instructions. For the best surface finish, take light finishing passes and maintain correct router speed for the material. Keep cutters clean and store in a protective case to prevent damage to the cutting edges.
