Product Description
CMT V-Grooving Bit - 90 deg. - 3/8" Diameter x 1/2" Cutting Height - 1/4" Shank is a precision carbide-tipped routing bit engineered for clean, sharp V-shaped cuts across a wide range of woodworking and fabrication tasks. With its 90 deg. included angle and double cutting edge design, this bit is well suited for sign making, decorative lettering, chamfering panel edges, and engraving work on materials ranging from solid wood to plasterboard panels. The compact 1/4" shank and 1 3/4" total length make it compatible with handheld routers, router tables, and CNC routing machines, giving woodworkers and fabricators a versatile tool for both shop and production environments.
Key Features
- 90 deg. V-Grooving Angle - produces crisp, symmetrical V-shaped grooves ideal for chamfering, lettering, and decorative panel work without secondary cleanup passes.
- Double Cutting Edge (2 Teeth) - dual flutes distribute cutting load evenly across the workpiece, resulting in smoother groove surfaces and reduced chipping on finished panels, drawer fronts, and laminates.
- Carbide-Tipped (HW) Cutting Material - industrial-grade hard metal carbide retains a sharp edge through extended use on hardwood, softwood, MDF, chipboard, melamine, and plastic, reducing the frequency of bit replacement.
- Right-Hand (RH) Rotation - compatible with the standard spindle direction of routers and CNC machines, ensuring immediate drop-in use without any machine modification.
- 1/4" Shank Diameter - fits a wide range of standard router collets, making this bit accessible for both entry-level and professional-grade routing equipment.
- Compact 1 3/4" Total Length - the short profile reduces vibration and deflection during cuts, helping maintain straight, consistent groove geometry especially on detailed engraving work.
Why This Product
- The 90 deg. cutting angle delivers perfectly balanced V-grooves in a single pass - no repositioning or multiple setups required - making this bit efficient for production sign making and batch panel chamfering.
- With a 1/2" cutting height and 3/16" secondary cutting height (I1), this bit handles a practical range of groove depths, giving woodworkers flexibility across thin veneered panels, MDF, and thicker solid wood stock.
- The hard metal carbide construction holds up across demanding materials including melamine, chipboard, laminates, and plastic - reducing bit swaps and downtime when working through mixed-material projects.
- The 1/4" shank makes this bit compatible with compact routers, full-size routers, and CNC spindles alike, so it transitions easily between handheld routing tasks and table or machine-based production runs.

Frequently Asked Questions
What materials can this V-grooving bit cut?
This bit is designed to cut solid hardwood, softwood, plywood, MDF, chipboard, laminates, melamine, and plastic. The hard metal carbide (HW) cutting edges maintain sharpness across this wide range of panel and sheet materials.
What is the difference between the 1/2" cutting height and the 3/16" cutting height (I1)?
The 1/2" cutting height (I) represents the total usable cutting depth of the bit, while the 3/16" measurement (I1) refers to a secondary cutting height dimension specific to the geometry of this V-grooving bit. Together they describe the full cutting profile of the tool.
Can this bit be used on a CNC routing machine?
Yes. The right-hand (RH) rotation and 1/4" shank are compatible with CNC routing machines that accept 1/4" collets, in addition to handheld routers and router tables. The 90 deg. V-groove profile is commonly used for CNC sign making and engraving applications.
How deep of a V-groove can this bit produce?
With a 3/8" diameter and a 90 deg. included angle, the groove width at maximum cutting depth equals the cutting diameter. The total cutting height of 1/2" defines the maximum groove depth achievable in a single pass, making it well suited for decorative chamfers, lettering grooves, and panel scoring.
