CMT Ball End Bit - 1 in. Diameter, 1/2 in. Radius, 1/2 in. Shank is a precision-ground carbide routing bit engineered to cut smooth, spherical-bottom channels and rounded grooves in a single pass. Designed for woodworkers, cabinetmakers, and CNC operators who need consistent, clean results, this ball end router bit is equally at home in handheld routers, router tables, and CNC routing machines. Whether you are carving decorative profiles, sculpting 3D contours, or routing channels for pipes or cables, this bit delivers the accuracy and durability that demanding applications require.

Key Features

• 1 in. Cutting Diameter with 1/2 in. True Radius - produces a perfectly spherical groove profile, giving you smooth, rounded channel bottoms without secondary cleanup passes.
• 15/16 in. Cutting Height - provides substantial depth capacity in a single setup, reducing the number of passes needed for deeper channels and improving workflow efficiency.
• 2-Flute (2-Tooth) Carbide Design - the two cutting edges work together to balance chip load and heat, resulting in cleaner cuts with less vibration across hardwoods, softwoods, sheet goods, and plastics.
• HW (Hard Metal / Carbide) Cutting Material - industrial-grade carbide maintains a sharp cutting edge longer than high-speed steel alternatives, extending the service life of the bit even through abrasive materials like MDF and laminates.
• 1/2 in. Shank Diameter - the full 1/2 in. shank provides maximum stability and reduced vibration in the collet, improving cut quality and reducing chatter marks in finished surfaces.
• Right-Hand Rotation - compatible with standard router collets on handheld routers, router tables, and CNC machines without any special setup requirements.
• 2-3/4 in. Total Length - provides adequate reach for typical routing depths while keeping the bit rigid enough to minimize deflection during cutting.
• Single-Pass Cable and Pipe Channel Routing - purpose-built geometry allows routing of full rounded channels for pipes or cables in one pass, saving time on repetitive production tasks.

Why This Product

• The 1/2 in. true radius profile creates perfectly rounded groove bottoms in one pass - ideal for woodworkers and tradespeople who need to route channels for cables or pipes without using multiple bits or making repeated depth adjustments.
• The 1/2 in. shank diameter - the largest standard shank size for router bits - means this bit seats firmly in compatible collets, reducing runout and chatter that can compromise surface finish on decorative profiles and carved contours.
• Hard metal carbide cutting edges hold their sharpness through high-volume routing in abrasive materials like MDF, chipboard, and laminates, making this bit a practical choice for production environments where consistent results across many cuts matter.
• The 2-flute geometry balances cutting load evenly, which translates to smoother finishes in both solid hardwood and engineered wood products - reducing the need for extensive sanding after routing.
