Router Bit Milwaukee S8 three-wing round-over/profile cutter 18.7 mm radius, 52.5 mm diameter, 1 pc

The Milwaukee S8 three-wing round-over/profile router bit is designed for creating smooth, consistent rounded edges and decorative profiles on wood. With an 18.7 mm radius and a 52.5 mm overall diameter, this single-piece cutter works in both handheld and table routers to trim, finish edges and produce uniform profiles on solid wood, plywood and veneered panels.

Advantages

This three-flute design provides cleaner cuts and better chip evacuation compared with two-flute bits, reducing tear-out on edge work. The larger 18.7 mm radius produces pronounced rounded profiles while the 52.5 mm diameter ensures stable engagement with the workpiece. Built for woodworking applications, the cutter delivers repeatable results when used with appropriate router speeds and feed rates.

Suitable for (tasks / use cases)

• Rounding and profiling edges on solid wood and panel products
• Creating decorative edge profiles on furniture components
• Edge trimming and finishing after joinery or laminating
• Router table and handheld router operations for repeatable profiles

When it may not be suitable

This router bit is sized for larger round-over profiles; it may be excessive for fine or delicate mouldings that require a smaller radius. It is not intended for cutting metal, masonry or other non-wood materials and should not be used on brittle laminates without testing, as large-radius cuts can cause delamination if feed rates and support are inadequate.

Key specifications

• Profile type: three-wing (three-flute) round-over/profile cutter
• Radius: 18.7 mm
• Overall diameter: 52.5 mm
• Quantity: 1 piece
• Intended material: wood, plywood, veneered panels

How to use

Install the cutter in a compatible router collet and ensure it is securely tightened. Select a router speed appropriate for the cutter diameter and material—lower speeds for large diameters and harder woods. Make multiple light passes rather than removing the full profile in a single pass to reduce load on the cutter and prevent tear-out. Use a router table with fence support for repeatable edges or a guide on a handheld router to maintain consistent profiling. Always clamp the workpiece and feed against the cutter rotation for controlled cutting.

What to consider before purchase

• Check router collet and shank compatibility to ensure correct fit
• Confirm router power and speed range are suitable for a 52.5 mm diameter cutter
• Assess the material to be machined—test on scrap to verify finish and avoid delamination on veneers
• Plan for multiple passes for deep or large-radius profiles to prolong cutter life

Usage recommendations

Use dust extraction and eye and hearing protection when routing. For best surface quality, perform a final light trimming pass against the grain where possible, and periodically inspect the cutter for wear or damage. When working with veneered or laminated boards, support the cut edge and reduce feed speed to minimize chipping and lifting.
