The CMT 199.505.11 Solid Carbide Upcut Ball Nose Spiral Bit delivers precision 3D routing performance for woodworkers and CNC operators who demand clean, smooth curved surfaces on every pass. Built entirely from a special super-micrograin carbide formulation, this 1/2 in. diameter ball nose spiral bit is engineered for sculpting, relief carving, 3D profile machining, and panel sizing across a wide range of solid wood, wood composites, plastic materials, and laminates. The spherical tip geometry combined with an upcut spiral design makes this router bit a go-to choice for CNC routing machines, router tables, and handheld routers alike.

Key Features

• Special Super-Micrograin Carbide Formulation - produces and holds a keen cutting edge longer than standard carbide, meaning fewer tool changes and more consistent surface quality across extended production runs.
• Low-Angle Upcut Spiral Design - engineered specifically to shear wood cleanly and provide efficient chip ejection, so the tool runs cooler, edges last longer, and the work surface stays free of burning or tear-out.
• Solid Carbide Construction (HWM Material Grade) - the entire bit is manufactured from premium micrograin carbide rather than just the cutting tips, delivering superior wear resistance and allowing more resharpenings over the life of the tool.
• Ball Nose (1/4 in. Radius) Spherical Tip - produces smooth curved surfaces ideal for sculpting, relief carving, and 3D profile machining where rounded, flowing geometry is required.
• 2-Flute Cutting Configuration - balances chip clearance and cutting efficiency, making the bit well-suited for both aggressive material removal and fine finishing passes in a single setup.
• Right-Hand (RH) Rotation - compatible with the vast majority of standard CNC spindles, router tables, and handheld routers, ensuring straightforward drop-in use without special toolholding requirements.
• 1/2 in. Shank Diameter - provides a secure, stable connection in standard 1/2 in. collets, reducing vibration and improving surface finish quality on complex 3D profiles.

Why This Product

• The super-micrograin carbide formulation and low-angle spiral geometry work together to keep the tool running cooler during extended CNC sessions - reducing the risk of burning on hardwood, softwood, and plastic materials without sacrificing feed rate.
• With a 1 1/4 in. cutting height and a 3 in. total length, this bit handles deeper 3D relief routing passes that shorter carbide bits cannot reach, making it practical for panel sizing and sculpting applications in a single operation.
• Solid carbide construction throughout - not just carbide-tipped - means the bit can be resharpened multiple times while maintaining its original geometry, lowering the long-term cost per cut for high-volume woodworking and composite machining shops.
• Designed specifically for cutting, copying, panel sizing, and general routing on solid wood, wood composites, plastic materials, and laminates, this bit covers a broad range of CNC and manual router applications from a single tool selection.
