Product Description
The CMT V-Tongue and Groove Set is a precision-engineered router bit set designed to give woodworkers the freedom to create custom mouldings and decorative profiles far beyond what standard lumber shop offerings provide. With a 1-3/4 in. cutting diameter and a 1/2 in. shank, this two-piece set handles stock ranging from 3/4 in. to 1 in. thick, making it a versatile solution for crafting elaborate, repeating profiles through multiple passes. Whether you are working at a router table with a fence or exploring creative moulding combinations, this CMT set opens up dozens of profile possibilities that let you move well past average mill work.
Key Features
- V-Tongue and Groove design - the two matched bits work together to produce interlocking V-profiles, allowing clean, precise joints and decorative moulding details that fit together seamlessly.
- 1-3/4 in. cutting diameter - a large working diameter produces full, well-defined profiles in a single pass, reducing the number of setup changes needed when building up complex moulding patterns.
- 1/2 in. shank - the full 1/2 in. shank provides maximum rigidity and reduced vibration compared to smaller shanks, resulting in smoother cuts and improved surface finish on finished mouldings.
- Maximum material thickness of 3/4 in. to 1 in. - this range accommodates heavy moulding stock, so you can mill from thicker blanks and refine the profile to your desired final shape, just as CMT recommends.
- 2-flute (2-tooth) carbide-tipped (HW) construction - hard carbide cutting edges stay sharp through extended use on solid hardwoods and composite materials, delivering consistent profile quality across long production runs.
- Right-hand (RH) rotation - standard right-hand rotation is compatible with the vast majority of handheld routers and router tables, making this set a straightforward addition to an existing shop setup.
- Fence-guided operation - designed specifically for use with a fence, which ensures repeatable, accurate passes when milling multiple pieces to match, reducing setup time and material waste.
- Multiple-pass profile system - combining two or more passes with these bits allows woodworkers to produce dozens of elaborate moulding profiles from a single set, multiplying the value of one purchase across many different projects.
Why This Product
- Break free from off-the-shelf moulding limitations - because the set is built around a multi-pass system, woodworkers can combine passes to create custom profiles that simply are not available at standard lumber retailers, giving finished pieces a truly custom character.
- Handles the heavy stock that detail work demands - with a maximum material thickness of 3/4 in. to 1 in., this set is suited to milling from substantial blanks, so the profile can be shaped from full-thickness hardwood and then refined, rather than being constrained to thin stock.
- One set, dozens of profiles - the V-tongue and groove geometry is engineered for combination use, meaning a single investment in this set yields a wide range of moulding options depending on how the passes are sequenced and combined.
- Built for router table precision - the fence-guided design and 1/2 in. shank work together to keep the bit stable and the pass consistent, which is especially important when producing long runs of matching moulding for cabinetry, paneling, or architectural millwork.

Frequently Asked Questions
What is the maximum material thickness this set can handle?
This V-tongue and groove set is rated for a maximum material thickness of 3/4 in. to 1 in. CMT recommends milling from heavy stock and then refining the piece to the desired final shape, so starting with thicker blanks within this range gives you the most flexibility.
Do I need a router table to use this set, or can I use a handheld router?
CMT specifically recommends using these bits with a fence. A router table with a fence is the most practical and controlled setup for this type of profile work, since it allows consistent, repeatable passes across multiple pieces of moulding stock.
How many different profiles can I create with this two-piece set?
By combining two or more passes with the V-tongue and V-groove bits, woodworkers can produce dozens of elaborate moulding profiles from a single set. CMT provides example profile illustrations to help guide initial combinations, and further variations can be developed by experimenting with pass depth and sequence.
Is this set compatible with standard router equipment?
Yes. The 1/2 in. shank and right-hand (RH) rotation are standard configurations that are compatible with the vast majority of handheld routers and router tables designed to accept 1/2 in. collets, making this set straightforward to integrate into an existing shop setup.
