Router Bit Milwaukee S12 rounding 19/73 mm, model 4932500975, 1 piece

The Milwaukee S12 rounding router bit with 19/73 mm cutting geometry is a single-piece cutter designed to produce consistent rounded edges and profiles in wood and similar materials. Intended for use in routers that accept S12 shank tooling, this router bit provides a defined radius for finishing and edge-profiling operations in carpentry and joinery. The solid construction supports routine workshop and site work where repeatable edge rounding is needed.

Advantages

This rounding router bit offers stable cutting action and a predictable rounded profile thanks to its 19/73 mm dimensions and single-piece design. It delivers repeatable results for trimming and finishing tasks, is straightforward to install in routers that accept the specified shank size, and is suitable for a range of wood types and similar workpiece materials where a smooth radius is required.

Suitable for

• Rounding and profiling wooden edges for furniture and cabinetry
• Finishing work on solid wood, plywood and composite panels
• Carpentry tasks requiring consistent edge radii
• Router-based edge trimming and decorative profiling

When it may not be suitable

This router bit is designed specifically for round-edge profiling and is not intended for heavy material removal or rough shaping where larger-diameter cutters or multi-flute cutters would be more appropriate. It requires a router that accepts S12 shank tooling; it will not fit routers with incompatible collet systems without the correct adapter.

Key specifications

• Cutting profile: rounding edge with defined radius
• Radius/dimensions: 19/73 mm cutting geometry
• Shank compatibility: S12-style shank fitment
• Material compatibility: wood, plywood, and similar panel materials
• Package quantity: 1 piece

How to use

Secure the router bit in a router collet that matches the S12 shank size, ensuring the bit is fully seated and tightened to the router manufacturer's torque recommendations. Adjust router speed and feed rate according to the workpiece material—use moderate speeds and steady feed for hardwoods and slightly higher feed for softer materials. Make multiple light passes rather than removing the full radius in a single pass to reduce load on the cutter and achieve a cleaner finish. Always use proper workholding and edge guides when profiling to maintain consistent results.

What to consider before purchase

• Confirm your router accepts S12 shank tooling or purchase an appropriate adapter.
• Ensure the 19/73 mm radius matches the desired profile for your project.
• Verify compatibility with the types of wood or panel materials you will work with.

Usage recommendations

For best results, use steady, controlled passes and appropriate router speeds for the material. Inspect the edge after each pass and, if necessary, sand lightly to achieve the desired smoothness. Wear eye and hearing protection and follow standard router safety practices.
