The CMT 838.501.11 3 Piece Roundover Set gives woodworkers and cabinetmakers the versatility to tackle edge profiling tasks across a wide range of projects - all with a single purchase. This right-hand rotation, carbide-tipped router bit set includes three roundover bits in radii of 1/4", 3/8", and 1/2", all fitted to a 1/2" shank for compatibility with handheld routers, router tables, and CNC routing machines. Whether you are softening sharp corners on furniture components, shaping decorative edges on hardwood panels, or producing consistent rounded profiles on MDF and plywood, this three-piece set provides the radius options to match your specific edge profiling needs without switching between individual bit purchases.

Key Features

• 3-Piece Roundover Set (Radii: 1/4", 3/8", 1/2") - maximum flexibility for profiling multiple edge sizes across different projects, eliminating the need to purchase individual bits separately
• 1/2" Shank Diameter - the larger shank provides greater rigidity and reduced vibration during cutting, resulting in smoother edge profiles and better control at the router table or handheld
• 2-Flute (Z=2) Carbide-Tipped (HW) Cutting Edges - hard carbide material holds a sharp cutting edge longer than high-speed steel, extending service life when working with solid hardwood, softwood, plywood, MDF, chipboard, laminates, melamine, and plastics
• Right-Hand Rotation (RH) - compatible with the standard rotation direction of virtually all routers, ensuring safe and reliable operation right out of the box
• Ball-Bearing Guide Pilot - rides along the workpiece edge to deliver consistent cutting depth and a uniform roundover radius with every pass
• CMT Orange Shield Non-Stick Coating - prevents the bit from overheating, reduces pitch and resin buildup, and protects against corrosion - keeping bits performing cleanly pass after pass
• SinterHIP Industrial Chrome Carbide - carbide processed via Hot Isostatic Pressing prevents material failure under stress and extends the usable cutting life of each bit
• Tri-Metal Brazing (Silver-Copper-Silver) - provides a stronger bond between the carbide tip and the bit body, reducing the risk of tip separation when routing harder woods or composite materials
• Anti-Kickback Design - limits the depth of cut that can occur in a single pass, reducing the risk of dangerous kickback events during use

Why This Product

• Buying a three-piece set with 1/4", 3/8", and 1/2" radii covers the most common roundover sizes used in furniture making, cabinetry, and general woodworking - giving you the right profile for each job without purchasing bits one at a time
• The 1/2" shank size is the preferred choice for router table and heavier handheld routing work, offering improved stability and reduced deflection compared to smaller shank options
• The combination of SinterHIP carbide, Tri-Metal brazing, and Orange Shield coating means each bit in this set is built to maintain cutting performance over extended use in demanding materials including hardwood, MDF, and laminates
• Compatibility with handheld routers, router tables, and CNC routing machines makes this set a genuinely versatile addition to any woodworking shop, from production environments to custom one-off work
