Product Description
CMT V-Grooving and Signmaking Router Bit - 29/32" Diameter, 90 deg. Angle, 1/4" Shank is a precision-engineered routing tool built specifically for signmaking, lettering, and decorative V-groove work. Featuring a single indexable carbide insert knife in a super strength steel body, this bit delivers clean, sharp V-grooves in a wide range of materials. When one cutting edge dulls, simply rotate the insert to expose a fresh edge - extending the life of the bit without the need for regrinding. The 90 deg. included angle produces crisp, clearly defined grooves ideal for routed sign lettering and decorative routing applications on wood, sheet materials, and plastics.
Key Features
- Indexable Insert Knife Design - when the cutting edge shows signs of wear, rotate the insert to exploit the remaining cutting edges, maximizing knife life and reducing downtime without regrinding or replacement.
- 90 deg. V-Groove Angle - produces clean, well-defined V-grooves ideal for routed signmaking and lettering, where crisp edge definition matters most.
- Super Strength Steel Body - provides a rigid, stable platform for the insert knife, contributing to accurate cuts and consistent groove geometry on every pass.
- HW (Hardmetal/Carbide) Cutting Material - hard carbide cutting edges handle a broad range of materials including hardwood, softwood, MDF, plywood, chipboard, laminates, and plastics.
- 1/4" Shank Diameter - fits standard 1/4" collet routers, making this bit compatible with most handheld routers and router tables commonly found in sign shops and woodworking studios.
- Right-Hand Rotation - compatible with the standard right-hand rotation of conventional routers, requiring no special setup or tooling changes.
- 7/16" Cutting Height - provides sufficient depth capacity for signmaking grooves and decorative lettering profiles in a single pass on most common sign substrates.
Why This Product
- Cost-Effective for Sign Shops - the rotatable indexable insert means you get multiple cutting edges from a single knife, reducing the frequency and cost of replacements compared to solid carbide bits that require professional regrinding.
- Purpose-Built for Signmaking - the 90 deg. angle and 29/32" cutting diameter are specifically sized for routed sign lettering and V-groove decorative work, not a general-purpose compromise.
- Broad Material Compatibility - cuts cleanly through hardwood, softwood, MDF, plywood, chipboard, laminates, and plastics, giving signmakers the flexibility to work with virtually any sign substrate without switching bits.
- Compact 1/4" Shank for Handheld Use - the 1/4" shank suits both handheld routers and router tables, making it equally practical for freehand sign routing and template-guided production runs.

Frequently Asked Questions
What does "indexable insert knife" mean, and how do I rotate the cutting edge?
An indexable insert knife is a replaceable carbide tip secured to the bit body with a Torx locking screw. When one cutting edge shows signs of wear, you loosen the screw, rotate the insert to expose a fresh cutting edge, and re-tighten - no regrinding required. This extends the useful life of each insert before a full replacement is needed.
Will this bit work with my 1/2" collet router?
This bit has a 1/4" shank diameter. To use it in a router equipped with a 1/2" collet, you would need a 1/2"-to-1/4" collet reducer or a router that accepts interchangeable collets. Always confirm your router's collet compatibility before use.
What materials can this V-groove bit cut?
The HW (hardmetal carbide) insert is suited for use in hardwood, softwood, plywood, MDF, chipboard, laminates, and plastics - the range of substrates commonly used in sign blanks and decorative panels.
Is this bit suitable for use on a router table as well as a handheld router?
Yes. The 1/4" shank and right-hand rotation are compatible with standard router tables as well as handheld routers fitted with a 1/4" collet, making the bit practical for both freehand lettering and table-mounted template work.
