CMT V-Grooving Bit - 90 deg. - 1/2" Diameter x 1/2" Cutting Height - 1/4" Shank is a precision routing bit engineered for clean, accurate V-groove cuts in a wide range of wood and panel materials. Built with 2 cutting edges and carbide-tipped construction, this 90 deg. grooving bit is ideal for sign making, decorative lettering, chamfering panel edges, and engraving work on drawer fronts, solid wood, plywood, MDF, and plasterboard panels. Whether you're routing detailed lettering or creating precise chamfer grooves, this bit delivers consistent results in handheld router, router table, and CNC routing applications.

Key Features

• 90 deg. V-Groove Angle - produces sharp, symmetrical V-shaped channels ideal for chamfering edges, sign lettering, and decorative panel work, giving you clean geometry with every pass.
• 2 Cutting Edges (Double Flute) - dual cutting edges distribute load evenly during routing, reducing vibration and producing smoother groove surfaces with less tearout.
• Carbide-Tipped (HW) Construction - hard carbide cutting tips maintain a sharp edge longer than high-speed steel, extending tool life across demanding materials including hardwood, MDF, laminates, and melamine.
• 1/4" Shank - fits compact routers, trim routers, and standard router tables equipped with a 1/4" collet, expanding versatility for both bench and handheld use.
• 1/2" Cutting Diameter with 1/2" Cutting Height - delivers grooves up to 1/2" wide and 1/2" deep in a single pass, suitable for bold decorative cuts and functional chamfers alike.
• Right-Hand Rotation - designed for standard right-hand router operation, ensuring proper chip ejection and safe cutting direction in conventional router setups.
• 1 3/4" Total Length - compact overall length allows use in tight clearances and minimizes tool deflection during cutting, contributing to straighter, more accurate grooves.
• CMT Orange Shield Non-Stick Coating - prevents the bit from heating up during use, reduces pitch and resin buildup on cutting surfaces, protects against corrosion, and extends overall tool life compared to uncoated bits.
• SinterHIP Industrial Chrome Carbide - carbide processed via Hot Isostatic Pressing prevents material failure under stress and extends cutting life in demanding routing applications.
• Tri-Metal Brazing - Silver-Copper-Silver brazing bonds the carbide tip to the body, protecting the tip when cutting harder wood or composite materials and reducing the risk of failed welds.
• Anti-Kickback Design - controls the depth of cut per pass, minimizing kickback risk and improving operator safety during routing.

Why This Product

• The 90 deg. cutting angle makes this bit the right choice for sign makers and woodworkers who need sharp, symmetrical V-grooves for lettering, engraving, and chamfer work - all from a single bit profile.
• The 1/4" shank provides broad compatibility with compact trim routers and full-size router tables alike, so one bit works across multiple setups without needing a collet adapter.
• Carbide-tipped construction with SinterHIP processing and Tri-Metal Brazing means the cutting edges stay sharp longer and hold up in difficult materials like MDF, chipboard, laminates, and melamine - reducing the frequency of bit changes.
• CMT's Orange Shield non-stick coating reduces resin and pitch adhesion during cuts in solid hardwood, softwood, and panel products, keeping the bit cleaner and performing consistently over repeated use.
