CMT V-Grooving Bit - 90 deg. - 1 1/4" Diameter x 3/4" Cutting Height - 1/2" Shank is a precision carbide-tipped router bit engineered for clean, accurate V-groove routing in a wide range of wood panels and composite materials. Designed with two cutting edges and a 90 deg. angle, this bit excels at sign making, decorative letter engraving, chamfer edge work, and panel fold-line grooving. Whether you are working on drawer fronts, plasterboard panels, or engraving detailed lettering, this bit delivers consistent, professional-quality results with minimal material tearout.

Key Features

• 90 deg. V-Groove Angle - produces a precise, sharp V-profile in a single pass, making it ideal for chamfering edges, routing fold lines in panels, and carving clean decorative grooves without secondary cleanup passes.
• 1 1/4" Cutting Diameter - provides a wide groove footprint suited to bold lettering, sign making, and decorative work where a prominent V-channel is desired.
• 3/4" Cutting Height - allows sufficient depth capacity to groove through standard panel stock, giving you flexibility across a range of material thicknesses.
• 2-Tooth Carbide (HW) Construction - hard metal carbide cutting edges maintain sharpness longer than high-speed steel alternatives, reducing downtime for sharpening or replacement when routing abrasive materials like laminates, MDF, and melamine.
• 1/2" Shank Diameter - the larger shank diameter compared to 1/4" options reduces vibration and flex during the cut, resulting in smoother groove walls and improved dimensional accuracy.
• Right-Hand Rotation - compatible with standard router collets used in handheld routers, router tables, and CNC routing machines, ensuring straightforward setup without special tooling.
• CMT Orange Shield Non-Stick Coating - prevents the bit from overheating, reduces pitch and resin buildup on cutting edges, and protects against corrosion, extending the working life of the bit between cleanings.
• SinterHIP Industrial Chrome Carbide - carbide processed via Hot Isostatic Pressing (HIP) prevents material failure at the cutting edge and extends cutting life, especially in demanding continuous-use applications.
• Tri-Metal Brazing - the silver-copper-silver brazing method secures carbide tips with greater integrity when cutting harder wood or composite materials, reducing the risk of tip separation during use.
• Anti-Kickback Design - limits the depth of cut per pass and minimizes kickback forces, making the bit safer and easier to control in handheld and table-mounted routing operations.

Why This Product

• The 90 deg. V-groove geometry handles a near-endless range of tasks - from cutting fold lines in cabinet panels and drawer fronts to engraving signage lettering - making it a versatile addition to any router bit collection without requiring multiple specialty bits.
• The combination of HW carbide construction and CMT Orange Shield non-stick coating means the bit stays cleaner and sharper longer, which translates directly to fewer interruptions and a lower cost per cut when working through production runs of MDF, melamine, or laminate panels.
• SinterHIP carbide processing and Tri-Metal Brazing together address the two most common carbide bit failure modes - edge chipping and tip separation - giving you greater confidence when routing harder composites or working at higher feed rates on a CNC routing machine.
• At 1/2" shank with anti-kickback geometry, this bit is designed for controlled, stable performance in router table and CNC setups where consistent groove depth and smooth sidewalls are critical to finished product quality.
