Product Description
The CMT Contractor V-Grooving Bit is a precision carbide-tipped routing bit designed to cut clean, sharp V-shaped grooves in a wide range of wood and composite materials. Built with a 90 deg. cutting angle, a 1/2 in. cutting diameter, and a 1/4 in. shank, this bit is well suited for decorative panel work, drawer front detailing, sign engraving, letter routing, and chamfer groove applications. CMT's contractor-grade V-groove bit features two carbide-tipped cutting edges that deliver smooth, fast material removal with consistent results on panel fronts, solid wood, sheet goods, and more.
Key Features
- 90 deg. V-Groove Angle - produces a precise, symmetrical V-shaped channel ideal for decorative grooves, engraved lettering, and sign-making work where a crisp, defined groove profile is required.
- Two Carbide-Tipped Cutting Edges (HW Material) - hardmetal carbide tips deliver sharp, efficient cutting action that reduces tear-out and keeps edges clean through repeated use on hardwood, softwood, plywood, MDF, chipboard, laminates, melamine, and plastic.
- 1/4 in. Shank - fits a wide range of handheld routers and router tables, making this bit accessible to hobbyists and contractors using compact or standard router setups.
- 1/2 in. Cutting Diameter x 1/2 in. Cutting Height - sized for controlled, proportionate V-grooves in panel and drawer front applications without over-cutting, giving you decorative depth with clean transitions.
- Right-Hand Rotation (RH) - compatible with standard router spindle direction, so it mounts and runs correctly in conventional handheld routers, router tables, and CNC routing machines without special setup.
- 1 3/4 in. Total Length - compact overall length provides good bit stability and reduces deflection during cuts, contributing to straighter grooves and more consistent decorative results.
Why This Product
- The 90 deg. V-groove profile is one of the most versatile angles for decorative routing - making it a practical single-bit choice for panel fronts, drawer details, engraved signs, and chamfer edges all in one tool.
- With two sharp carbide-tipped cutting edges, this bit cuts smoothly and quickly through both solid wood and engineered sheet goods, reducing the number of passes needed and keeping project timelines efficient.
- The 1/4 in. shank makes this bit compatible with a broad range of router hardware - from compact trim routers to full-size router tables - giving it flexibility across different workspaces and project scales.
- At 1/2 in. cutting diameter and 1/2 in. cutting height, the bit is proportioned for controlled decorative work on panel and drawer fronts, letting you achieve clean, professional-looking V-grooves without removing excess material.

Frequently Asked Questions
What materials can this V-grooving bit cut?
This bit is designed to cut cleanly through solid hardwood, softwood, plywood, MDF, chipboard, laminates, melamine, and plastic. The two carbide-tipped cutting edges handle both natural wood and engineered sheet goods effectively.
What is the cutting angle of this bit, and why does it matter?
This bit cuts at a 90 deg. angle, which creates a symmetrical V-shaped groove suited for decorative panel work, drawer fronts, engraved lettering, and chamfer details. CMT also offers a 60 deg. V-groove angle as an alternative for applications requiring a narrower groove profile.
What type of router is this bit compatible with?
The 1/4 in. shank fits standard handheld routers, router tables, and CNC routing machines that accept 1/4 in. collets. The right-hand rotation is compatible with conventional router spindle direction, so no special configuration is needed.
How does the carbide-tipped construction benefit cutting performance?
The two hardmetal carbide (HW) cutting edges stay sharp longer than high-speed steel alternatives, delivering smooth, fast cuts with minimal tear-out. This makes the bit well suited for repeated decorative routing tasks on panels, signs, and drawer fronts where clean edge quality is important.
