The CMT 663.110.11 V-Groove and Folding CNC Bit is a precision-engineered router cutter designed for CNC machines, delivering a 110 deg. cutting angle across a 2-3/8 in. diameter to handle V-groove routing, miter folding, signmaking, lettering, and chamfer edge work. Built on a super strength steel body with a single high-grade HWM reversible knife insert, this bit gives CNC operators a versatile, cost-effective solution for a wide range of panel and sheet goods applications - from chipboard and plywood to laminated panels and MDF.

Key Features

• 110 deg. V-groove cutting angle at 2-3/8 in. diameter - produces clean, wide V-grooves and precise miter fold lines in a single pass, reducing setup time on CNC routers.
• High-grade HWM reversible knife insert - the reversible design means you flip the knife when one edge dulls, effectively doubling usable cutting life before a replacement is needed, lowering tooling cost per part.
• Super strength steel body construction - provides rigidity and vibration resistance during high-speed CNC passes, helping maintain cut accuracy and surface quality across large panel runs.
• 20mm shank diameter - fits standard 20mm CNC router collets, ensuring a secure, low-runout connection that supports consistent depth and angle control.
• Single right-hand rotation flute (1 tooth) - optimized chip clearance geometry for clean material evacuation, reducing heat buildup and keeping cut edges crisp on chipboard, plywood, and MDF.
• Upgraded knife option available for laminated and MDF material - a higher-quality knife is offered for demanding surface materials, allowing the same tool body to be reconfigured for more challenging workpieces.
• 21mm cutting height with 95mm total length - the generous cutting height accommodates typical panel folding and V-groove depths, while the compact overall length keeps the tool well-supported in the spindle for stable cutting performance.

Why This Product

• One tool body covers multiple CNC operations - V-groove routing, miter folding, signmaking lettering, and chamfer edging - making it a practical choice for shops that need versatility without switching bits constantly.
• The reversible HWM knife insert design means usable cutting edges are not wasted when one side dulls, making this bit more economical over time compared to solid brazed tools that require full replacement.
• The 110 deg. angle is well-suited for miter fold work on panels, allowing material to fold cleanly at the groove line - a critical outcome for cabinet, display, and signmaking applications where tight, precise folds are required.
• Compatibility with general-purpose materials like chipboard and plywood, plus an available upgrade knife for laminates and MDF, means this tool adapts to the actual material mix found in production CNC environments rather than being limited to a single substrate.
