Product Description
CMT Edge-Fluting Bit - 13/16" Diameter x 5/16" Cutting Height, 5/32" Radius, 1/4" Shank is a precision router bit from CMT designed to cut decorative fluted grooves along the edges of workpieces. Bearing guided for consistent, fence-free operation, this bit is well suited for curved screens, small-radius decorative grooves, cabinet doors, and drawer fronts. Whether used in a handheld router or a table-mounted setup, it delivers repeatable fluted profiles in solid wood, sheet goods, and composite panels.
Key Features
- Bearing-Guided Design - eliminates the need for a side fence, so you can follow straight or curved edges with ease and consistency, speeding up setup time on decorative routing tasks.
- 2-Flute Carbide Cutting Edges (HW Material) - hardmetal (carbide) cutters deliver clean, smooth fluted profiles and stay sharp through extended use in hardwood, softwood, MDF, and similar materials.
- Right-Hand Rotation - designed for standard router operation, making it directly compatible with virtually all handheld and table-mounted routers without any additional setup considerations.
- 1/4" Shank Diameter - fits a wide range of compact and full-size routers that accept 1/4" collets, giving this bit broad compatibility across router types and brands.
- 5/32" Radius Profile - produces a defined, graceful flute curve ideal for furniture edge details, door accents, and small decorative grooves where a precise radius is essential.
- Handheld or Table-Mounted Use - versatile enough for freehand routing along curved profiles or fixed table operation for production-style repetitive cuts, reducing the need for multiple specialized bits.
Why This Product
- The bearing-guided pilot means no side fence is required - you can follow curved edges and irregular shapes that a fence simply cannot track, opening up decorative possibilities on doors, curved panels, and screens.
- With a compact 1/4" shank and a total length of 2 1/4", this bit fits trim routers and standard routers alike, making it a practical choice for both shop and job-site edge-fluting work.
- The 5/32" radius and 13/16" diameter are sized specifically for small-radius fluting details - the kind of refined decorative groove used on cabinet door edges and furniture trim where proportion and precision matter.
- Two carbide cutting edges in a right-hand rotation pattern provide balanced cutting action, helping reduce vibration and produce a cleaner flute surface with less sanding required afterward.

Frequently Asked Questions
Does this bit require a side fence to guide it along the workpiece edge?
No. The CMT 862.040.11 is a bearing-guided edge-fluting bit, meaning the ball-bearing pilot rides directly along the workpiece edge to control the cut. No side fence is required, which makes it especially useful for routing curved or irregular edges that a fence cannot follow.
Can this bit be used in both a handheld router and a router table?
Yes. This bit is compatible with both handheld and table-mounted router setups. The bearing guide handles depth control in either configuration, so setup is straightforward regardless of how you prefer to work.
What shank size does this bit use, and which routers will it fit?
This bit has a 1/4" shank diameter. It is compatible with any router - handheld or table-mounted - that accepts a 1/4" collet, which includes most compact trim routers and many full-size routers equipped with a 1/4" collet option.
What type of flute profile does this bit produce?
This bit cuts a curved flute profile with a 5/32" radius along a 5/16" cutting height. The resulting groove is a concave, semi-circular channel suited for decorative edge details on cabinet doors, drawer fronts, furniture panels, and similar woodworking applications.
