CMT Roundover Bit with Bearing - 1-3/4" Diameter, 5/8" Radius, 1/4" Shank is a professional-grade carbide-tipped router bit engineered to produce smooth, consistent roundover profiles on wood edges and workpieces. With a generous 5/8" radius and a 1-3/4" cutting diameter, this bit handles substantial edge-profiling tasks that range from softening sharp corners on furniture components to creating decorative profiles on solid hardwood, plywood, and MDF panels. The ball-bearing guide rides along the workpiece edge to maintain a uniform depth of cut throughout the pass, delivering repeatable results on every run.

Key Features

• Hardwood Carbide (HW) Cutting Material - tungsten carbide cutting edges stay sharp longer through dense hardwoods and composite sheet goods, reducing the frequency of bit changes and downtime.
• 2-Flute Design - two cutting edges produce a balanced cut with improved surface finish and reduced vibration, leaving less tear-out on figured wood and veneer faces.
• Ball-Bearing Pilot Guide - the bearing rolls along the stock edge and controls cutting depth automatically, eliminating the need for a fence on most profiling operations and ensuring consistent results pass after pass.
• 1/4" Shank - fits a wide range of compact routers and trim routers, making this bit accessible to woodworkers who do not own a full-size router.
• Right-Hand (RH) Rotation - standard rotation matches conventional router motor direction, so no special tooling or setup changes are required.
• 5/8" Radius Profile - produces a substantial, flowing roundover that suits furniture edges, cabinet doors, shelf nosings, and decorative millwork where a bold profile is desired.
• Fatigue-Proof Steel Body - the bit body is manufactured from fatigue-proof steel, which resists flex and stress fracture under load, adding a margin of safety and extending service life.
• Carbide-Tipped Cutting Edges - tipped construction allows the steel body to remain tough and impact-resistant while the carbide edges handle abrasive cutting contact, a combination that outperforms solid HSS bits in wear resistance.

Why This Product

• Suitable for router table use with large profiles - bits featuring a radius of 1" or larger are intended for use on a router table, and at 5/8" radius this bit is well suited to that setup, giving operators the stability and control needed when shaping larger profiles in hardwood.
• Versatile material compatibility - the carbide-tipped cutting edges handle solid hardwood, softwood, plywood, MDF, chipboard, laminates, melamine, and plastic, making this a single bit that covers a broad range of shop tasks without swapping tools.
• 13-radius CMT roundover family - this bit is part of a 13-radius lineup, so woodworkers who need multiple profiles can build a matched set from the same manufacturer for consistent quality and coating standards across their bit collection.
• Bearing guide simplifies freehand edge profiling - because the bearing pilot registers directly against the workpiece, operators can profile curved or irregular edges without needing a fence or template, expanding the range of shapes this bit can handle.
