CMT V-Grooving Bit with Bearing - 90 deg. - 1/2" Diameter - 1/4" Shank is a precision carbide-tipped routing bit engineered for clean, accurate V-groove cuts across a wide range of woodworking and fabrication tasks. With its 90 deg. cutting angle, integrated bearing guide, and double cutting edge design, this bit excels at sign making, decorative lettering, chamfering, and panel grooving - delivering professional results in solid hardwood, softwood, plywood, MDF, chipboard, laminates, melamine, and plastic.

Key Features

• 90 deg. V-Groove Cutting Angle - produces sharp, symmetrical V-shaped channels ideal for lettering, decorative engraving, chamfer grooves, and panel fold lines with consistent geometry on every pass.
• Bearing Guide Included - the integrated bearing allows the bit to follow a template or straight edge precisely, giving you repeatable, guided cuts without the need for a separate fence setup.
• Double Cutting Edge (2-Flute Design) - two carbide cutting edges work together to remove material more efficiently and leave a smoother surface finish, reducing the need for sanding or cleanup after routing.
• HW (Carbide) Blade Material - tungsten carbide construction delivers long-lasting edge retention and durability when routing hardwoods, composites, laminates, and panel materials, extending the service life of the bit well beyond high-speed steel alternatives.
• Right-Hand Rotation - matches the standard rotation direction of handheld routers, router tables, and CNC routing machines, ensuring safe, predictable performance with conventional equipment.
• 1/2" Cutting Height with 1/4" Lower Cutting Height - the dual cutting height configuration gives you flexibility in groove depth, allowing both full-depth and partial-depth passes to suit different panel thicknesses and design requirements.
• 1/4" Shank Diameter - fits 1/4" collets on a wide range of compact routers and standard routing machines, making this bit accessible without requiring a heavy-duty collet upgrade.
• Compact 1 3/4" Total Length - the short overall profile keeps the bit stable and reduces deflection during cutting, contributing to straighter grooves and cleaner results.
• CMT Orange Shield Non-Stick Coating - prevents the bit from overheating during extended use, reduces pitch and resin buildup on the cutting edges, protects against corrosion, and extends overall tool life - meaning less downtime for cleaning and bit replacement.
• SinterHIP Industrial Chrome Carbide - the carbide is processed via Hot Isostatic Pressing (HIP), a manufacturing method that eliminates internal material voids and prevents carbide failure, resulting in a longer-lasting cutting edge even under demanding routing conditions.
• Tri-Metal Brazing (Silver-Copper-Silver) - the three-layer brazing bond secures each carbide tip with exceptional strength, reducing the risk of tip separation when routing harder woods or composite materials and adding a critical safety margin during heavy-use applications.
• Anti-Kickback Design - controls the feed rate and limits the bite the bit can take in a single pass, reducing the risk of dangerous kickback events and improving operator safety during freehand and table-mounted routing.

Why This Product

• Versatile V-grooving for panels and decorative work - the 90 deg. cutting angle covers the most common V-groove applications, from drawer front fold lines and panel chamfers to engraved signage and decorative lettering, all with a single bit.
• Bearing guide eliminates the need for a separate fence - for template-guided work or straight-edge routing, the integrated bearing lets you make accurate, repeatable cuts without additional jigs, saving setup time on production runs.
• CMT's carbide processing and coating technology extends cutting life - the combination of SinterHIP carbide, Tri-Metal Brazing, and the Orange Shield coating means this bit holds its edge longer and requires less frequent replacement compared to uncoated carbide bits, reducing cost per cut over time.
• Compatible with handheld routers, router tables, and CNC machines - the standard 1/4" shank and right-hand rotation make this bit a drop-in fit for the most common routing setups in woodworking shops and sign-making operations, with no special tooling required.
