CMT V-Groove and Folding CNC Router Bit - 2-3/64 in. Diameter, 91 deg. Angle, 20mm Shank is a professional-grade CNC router cutter engineered for V-groove routing, miter folding, signmaking, lettering, and chamfer edge work. Built on a super strength steel body and fitted with a high-grade HWM reversible knife, this single-tooth right-hand rotation bit delivers clean, precise cuts across a wide range of panel and sheet materials. Whether you are routing decorative V-grooves, preparing fold lines in sheet goods, or cutting crisp chamfer edges for signage, this tool provides the versatility and reliability demanded by production CNC environments.

Key Features

• 91 deg. V-groove cutting angle - produces a precise, shallow-angle groove ideal for miter folds, decorative chamfers, and signmaking lettering without over-cutting into the panel face.
• Super strength steel body - provides a rigid, stable platform that resists deflection during high-speed CNC passes, maintaining dimensional accuracy cut after cut.
• High-grade HWM reversible knife - the single replaceable knife can be flipped to expose a fresh cutting edge, reducing tooling cost and downtime compared to solid carbide designs.
• Optimized for general-purpose materials, chipboard, and plywood - performs cleanly on a broad range of substrate types commonly used in cabinet making, display fabrication, and sign production.
• Higher-grade knife option available for laminated panels and MDF - allows operators to match knife specification to material hardness, protecting edge quality on demanding substrates.
• 20mm shank diameter - designed for industrial CNC router spindles, ensuring a secure, vibration-free hold during extended production runs.
• 25mm cutting height - accommodates a meaningful depth of engagement, making it suited for full-depth V-groove folding passes on typical panel thicknesses.
• Right-hand rotation (RH) - compatible with standard CNC router spindle direction, requiring no special spindle configuration.
• 4 in. total length - provides adequate reach for toolholder clearance while keeping the cutting geometry compact and controllable.

Why This Product

• The 91 deg. included angle combined with a 25mm cutting height makes this bit a practical single-tool solution for both V-groove decoration and fold-line preparation, eliminating the need to switch between separate cutters for these related operations.
• The reversible HWM knife design means you get at least two cutting edges per knife insert, lowering per-cut tooling cost on high-volume CNC runs compared to non-reversible solid carbide bits.
• With compatibility across chipboard, plywood, solid hardwood, and softwood - plus an upgrade knife path for laminates and MDF - this cutter adapts to the mixed-material demands of busy fabrication shops without requiring multiple bit SKUs.
• The 20mm industrial shank targets CNC router spindles directly, offering the rigidity and concentricity that high-feed-rate production routing requires, reducing chatter and improving finished edge quality.
