Router Bit MILWAUKEE S8 Round-Over 12.7 mm Radius, 50.8 mm Cutting Length

The MILWAUKEE S8 Round-Over router bit with a 12.7 mm radius and 50.8 mm cutting length is a single-piece cutter designed for edge profiling on timber, veneered panels and moldings. Sized for woodworking routers and trimmers, it is intended to produce consistent rounded edges and smooth profiles for finishing, cabinetry and decorative trim work. The steel body and precision ground cutting geometry ensure repeatable results when trimming and shaping edges.

Advantages

This round-over bit provides a precise 12.7 mm radius for uniform edge rounding and a long 50.8 mm cutting length that allows deeper passes or extended reach on thicker stock. The one-piece construction reduces vibration and improves stability, while the sharp profile delivers clean cuts with minimal tear-out on solid wood and veneered surfaces. The bit is compatible with common woodworking routers and trimmers, making it suitable for both shop and on-site use.

Suitable for

• Rounding edges on solid wood boards and timber components
• Edge profiling of veneered panels and laminated surfaces
• Cabinet door and drawer front finishing
• Decorative trim and molding profiling
• Finishing passes on furniture components

When it may not be suitable

This router bit is designed specifically for edge rounding and may not be appropriate for tasks that require complex profiles, grooving, or joinery cuts. It is not intended for use on metal, masonry, or other non-wood materials. For extremely delicate veneers or highly figured timbers prone to tear-out, test cuts are recommended and a shallower pass may be necessary to achieve the desired finish.

Key specifications

• Radius: 12.7 mm
• Cutting length: 50.8 mm
• Application: edge round-over profiling
• Construction: single-piece cutter
• Compatible with: handheld routers and trimmers designed for router bits

How to use

Install the router bit securely in the collet of a router or trimmer following the tool manufacturer's instructions, ensuring the bit is seated and tightened properly. Set the router speed appropriate for the material and make progressive shallow passes rather than trying to remove the entire amount in one cut. Use a straight, steady feed direction and support the workpiece to minimize vibration. When working with veneered or delicate surfaces, consider backing the cut area or using a sacrificial fence to prevent chipping. After use, clean the bit and inspect for wear before storing.

What to consider before purchase

• Ensure your router or trimmer accepts the shank diameter of the bit
• Confirm the 12.7 mm radius and 50.8 mm cutting length match the profile and stock thickness you require
• Check material compatibility—designed for wood, veneered panels and moldings only
• Plan to make multiple shallow passes on hardwoods or delicate veneers to reduce tear-out

Usage recommendations

For best results, use the MILWAUKEE S8 round-over bit at the recommended router speed for the wood species, make several light passes instead of a single heavy cut, and support the workpiece to reduce vibration. Regularly inspect and sharpen or replace the bit when cutting quality diminishes.
