Router bit Makita D-09444 round-over cutter 45 mm length 25.4 mm cutting diameter

Makita D-09444 round-over cutter is a router bit intended for edge profiling and rounding of solid wood and wood-based materials. With an overall length of 45 mm and a cutting diameter of 25.4 mm, this cutter produces consistent, smooth rounded edges suitable for furniture, doors, mouldings and general joinery work. The geometry of the cutting edges is optimized for clean cuts and reduces tear-out on edges when used with appropriate feed and router speed.

Advantages

The cutter offers a precise cutting diameter of 25.4 mm and a compact length of 45 mm for controlled routing in handheld and table-mounted routers. Its profile produces uniform rounding along the edge while maintaining surface quality, which reduces sanding time. The design provides stable cutting performance for repeated passes and typical woodworking applications.

Suitable for

• Edge rounding and profiling on solid wood
• Finishing edges of plywood, MDF and particleboard
• Creating rounded edges on furniture components and doors
• General joinery and trim work requiring a smooth radius

Key specifications

• Overall length: 45 mm
• Cutting diameter: 25.4 mm
• Profile type: round-over (edge radius based on cutting diameter)
• Intended materials: wood and wood-based panels
• Compatibility: handheld and table-mounted routers with appropriate collet

How to use

Install the round-over cutter into a router collet sized to match the cutter shank, and tighten the collet according to the router manufacturer's instructions. Set router speed and feed rate appropriate for the workpiece material; slower feed and higher speed generally reduce tear-out on hardwoods, while lower speeds may be needed for some engineered boards. Make light trial passes to establish the correct cutting depth and perform multiple shallow passes rather than removing the full profile in one pass for cleaner results and reduced stress on the cutter. Use a router table or edge guide for consistent runs on long boards.

Usage recommendations

Always wear appropriate eye and hearing protection and use dust extraction when routing. Secure the workpiece firmly and allow the cutter to reach full speed before engaging the edge. For best finish, feed against the rotation of the cutter and consider a final light pass to remove any remaining tool marks.
