Router Bit Milwaukee model 4932501030 S8 three-flute profile cutter for edge rounding, cutter diameter 38.1 mm, bearing 61 mm, 1 pc

Milwaukee router bit model 4932501030 is an S8 three-flute profile cutter designed for edge rounding and profiling on a variety of wood materials. With a cutter diameter of 38.1 mm and a bearing diameter of 61 mm, this single-piece cutter is intended for use with compatible routers to produce consistent rounded edges and clean profile finishes on solid wood and engineered boards.

Advantages

The three-flute design provides smoother cuts and improved chip evacuation compared with two-flute profile cutters, which helps reduce tear-out and delivers a finer surface finish. The S8 geometry is optimized for edge rounding and profiling, enabling uniform results along long edge runs. Supplied as one sturdy cutter, it is built for stable operation at typical router speeds and offers repeatable profiling when used with correct router settings and guide bearings.

Suitable for

• Edge rounding and radius profiling on solid wood
• Trimming and finishing profiles on plywood, MDF and other manufactured boards
• Producing consistent decorative edges on furniture components and cabinet doors
• Use with handheld or table-mounted routers that accept the cutter size

When it may not be suitable

This cutter is intended for wood and wood-based materials; it is not suitable for cutting metals, masonry, or other non-wood workpieces. Very hard or abrasive materials, or work performed at inappropriate feed rates or router speeds, can accelerate wear and reduce cutter life. For very fine decorative details or extremely small radii, a different profile or smaller-diameter cutter may be more appropriate.

Key specifications

• Cutter type: S8 three-flute profile cutter for edge rounding
• Cutter diameter: 38.1 mm
• Bearing diameter: 61 mm (guide bearing included as specified)
• Number of pieces in package: 1
• Primary material compatibility: solid wood, plywood, MDF and similar manufactured boards

How to use

Install the cutter into a router collet that matches the shank diameter and ensure it is securely tightened before operation. Set the router speed and feed rate according to the material and cutter diameter—moderate speeds and steady feed provide cleaner cuts for profile cutters of this size. Use the bearing to follow the workpiece edge or a template, and perform test cuts on scrap material to confirm depth and profile before machining the final workpiece. Always clamp the workpiece firmly and use appropriate push blocks or featherboards for safe, controlled passes.

What to consider before purchase

• Ensure router collet and shank diameter compatibility with your router
• Confirm that the 38.1 mm cutter diameter and 61 mm bearing suit the desired edge radius and available workpiece dimensions
• Verify material compatibility—intended for wood and engineered boards, not for metals or masonry
• Plan for appropriate router speed and feed to avoid excessive wear or tear-out

Usage recommendations

For best results, make multiple light passes rather than removing the full depth in a single pass. Keep the cutter sharp and inspect the bearing for smooth rotation. Use dust extraction and personal protective equipment such as eye and hearing protection when routing.
