Product Description
CMT Contractor V-Grooving Bit - 7/16 in. Diameter, 60 deg. Angle, 1/4 in. Shank is a precision carbide-tipped routing bit engineered for creating clean, sharp V-shaped grooves in panel fronts, drawer fronts, and decorative woodworking projects. With its 60 deg. included angle and two razor-sharp carbide cutting edges, this bit delivers smooth, fast material removal whether you are engraving letters for signage, adding decorative detail to cabinetry, or routing crisp V-grooves in a wide range of wood-based panels. Designed for right-hand rotation and compatible with standard 1/4 in. shank routers and router tables, this CMT bit is a reliable choice for both professional and contractor-level V-grooving work.
Key Features
- 60 deg. V-groove angle - produces a narrow, precise groove profile ideal for decorative panel work, sign lettering, and engraving applications where clean angular detail is essential.
- 7/16 in. cutting diameter - compact diameter gives you control in tight decorative passes while maintaining the groove geometry needed for crisp lettering and panel accents.
- Two carbide-tipped cutting edges (HW material) - hard carbide tips stay sharper longer than high-speed steel, delivering smooth, fast cuts with reduced tear-out on solid wood, plywood, and panel products.
- 9/16 in. cutting height - sufficient cutting depth to complete decorative V-grooves in standard panel and drawer front stock in a single pass.
- 1/4 in. shank - fits a wide range of handheld routers, router tables, and CNC machines equipped with 1/4 in. collets, making this bit highly versatile across your existing tool setup.
- Right-hand (RH) rotation - matches the standard rotation direction of virtually all routers, ensuring proper chip ejection and clean groove walls without chatter.
- 1 3/4 in. total length - compact overall length keeps the bit rigid and minimizes vibration, contributing to cleaner groove edges and more consistent results pass after pass.
Why This Product
- The 60 deg. angle makes this bit the right choice when you need a sharper, more defined groove profile for sign lettering or fine decorative detailing - applications where a wider 90 deg. groove would look too broad or shallow.
- Two carbide-tipped cutting edges mean faster feed rates and longer tool life compared to single-flute designs, making this bit efficient for repeat production runs on drawer fronts and cabinet panels.
- The 1/4 in. shank broadens compatibility so this bit works across a wide range of router platforms - from compact trim routers to full-size router tables - without requiring a collet adapter.
- At 9/16 in. cutting height and 7/16 in. diameter, the geometry is sized specifically for decorative V-grooving rather than heavy stock removal, giving you precise, repeatable results on finished panel surfaces.

Frequently Asked Questions
What is the difference between the 60 deg. and 90 deg. V-groove angle options for this type of bit?
A 60 deg. angle produces a narrower, more defined groove that is well suited for fine sign lettering, engraving, and sharp decorative details. A 90 deg. angle creates a wider, more open groove profile better suited for broader decorative chamfers and panel detailing. CMT offers both angle options in their V-grooving bit line so you can match the groove geometry to your specific project requirements.
Is this bit compatible with a CNC routing machine?
Yes. The 1/4 in. shank and right-hand rotation of the CMT 85801 make it compatible with handheld routers, router tables, and CNC routing machines that accept a 1/4 in. collet. Always verify your machine's collet size and RPM rating before use.
What materials can this V-grooving bit cut?
This bit features carbide-tipped (HW) cutting edges designed for use in solid hardwood, softwood, plywood, MDF, and similar wood-based panel products commonly used in decorative panel fronts, drawer fronts, and sign blanks.
How many cutting edges does the CMT 85801 have, and why does that matter?
The CMT 85801 has 2 carbide-tipped cutting edges. A two-flute design provides a balance of smooth surface finish and efficient chip clearance, allowing for faster feed rates and cleaner groove walls compared to single-edge bits - particularly useful when routing decorative grooves across panel grain.
