Router bit DeWalt DT90003 — shank 8 mm, cutting diameter 8 mm, cutting length 20 mm, overall length 55 mm

The DeWalt DT90003 router bit features an 8 mm shank, an 8 mm cutting diameter, a 20 mm cutting length and a 55 mm overall length. It is intended for use in handheld routers and router tables for edge profiling, grooving and trimming in solid wood and wood-based panels. The bit’s dimensions provide a medium cutting reach suitable for common joinery and finishing tasks where standard 8 mm shank compatibility is required.

Advantages

The solid construction and industry-standard shank size ensure secure collet fitment and stable rotation at typical router speeds. The 20 mm cutting length gives sufficient depth for grooves, rabbets and profile cuts while the 8 mm diameter balances cutting strength with maneuverability. Its overall length of 55 mm allows use in both handheld routers and table-mounted setups without excessive overhang. The geometry of the cutting edges is suitable for clean cuts in wood and composite boards when operated at appropriate feed rates.

Suitable for

• Edge profiling and decorative moulding on furniture components
• Grooving and slot cutting for joinery and loose-tenon work
• Trimming laminate and veneered panels
• General routing tasks in hardwoods, softwoods and wood-based panels

Key specifications

• Shank diameter: 8 mm
• Cutting diameter: 8 mm
• Cutting length: 20 mm
• Overall length: 55 mm
• Compatible with handheld routers and router tables using 8 mm collets

How to use

Secure the router bit in the router collet and tighten according to the router manufacturer’s instructions. Set router speed and feed rate appropriate for the workpiece material and the 8 mm cutting diameter; higher speeds with steady feed rates typically yield cleaner cuts in softwoods, while slower passes may be needed for hardwoods or coated panels. Make progressive passes to reach full depth when cutting deeper grooves or profiles. Use a router table and fence for repeatable edge work and maintain secure clamping of the workpiece for safety and accuracy.

Usage recommendations

Wear eye and hearing protection, and use dust extraction when routing wood and composites. Inspect the bit for sharpness and balance before use and replace or re-sharpen when cutting performance degrades. Avoid side-loading the bit; allow the cutting geometry to work with steady, controlled feeds to prolong tool life.
