Product Description
The CMT Contractor Roundover and Beading Bit with a 1/4 in. radius and 1/4 in. shank delivers clean, consistent edge profiles on wood and wood-composite materials. Designed for craftspeople who need reliable performance on furniture edges, cabinet faces, and decorative trim work, this bit softens sharp corners into smooth, rounded profiles while also producing a classic bead detail. When paired with a cove bit, it opens up joinery possibilities like drop-leaf table edges and other multi-step decorative profiles - making it a practical choice for both shop routing and handheld router work.
Key Features
- 2-Flute Carbide-Tipped Cutting Edges - dual carbide tips (HW material grade) deliver efficient chip removal and a smooth surface finish, reducing the need for sanding after routing.
- Anti-Kickback Body Design - limits the depth of cut on each pass, reducing the risk of sudden kickback and improving control and safety when edge profiling.
- Heat-Treated Shank and Body - increases the overall durability and strength of the bit, helping it withstand the stresses of repeated use in both handheld routers and router tables.
- Bottom Bearing Included - the integrated ball-bearing pilot guides along the workpiece edge for consistent depth and a uniform radius profile without the need for a fence setup.
- Right-Hand Rotation - standard RH rotation is compatible with virtually all handheld routers, router tables, and CNC routing machines for broad versatility.
- 1/4 in. Shank - fits 1/4 in. collets found on a wide range of compact and full-size routers, giving this bit broad machine compatibility.
- Roundover and Beading Profile Combination - one bit produces both a roundover and a bead detail, offering multi-profile flexibility without a tool change.
Why This Product
- The combined roundover and beading profile in a single bit saves setup time compared to using separate profile bits - ideal for furniture edge work and decorative trim where both profiles are needed on the same project.
- The anti-kickback design makes this bit a safer choice for users routing solid hardwood, plywood, and MDF, where feed rate inconsistencies can otherwise lead to sudden bit grab.
- The included bottom bearing eliminates the need for a separate router fence when profiling straight or curved edges, making freehand and template-guided routing more accessible.
- The heat-treated shank and body paired with carbide-tipped cutting edges means this contractor-grade bit holds up through extended shop use without frequent resharpening or replacement.

Frequently Asked Questions
Can this bit be used in both a handheld router and a router table?
Yes. The 1/4 in. shank is compatible with 1/4 in. collets found on handheld routers, router tables, and CNC routing machines. The right-hand rotation is standard for all of these machine types.
Does this bit produce only a roundover, or does it also cut a bead?
This bit is designed as a combined roundover and beading profile. Depending on the height adjustment of your router, you can expose either the roundover profile alone or include the bead detail at the base of the profile - giving you two decorative edge options from a single bit.
What is the purpose of the anti-kickback design on this bit?
The anti-kickback body geometry limits how much material the bit can remove in a single pass. This controls the cut depth and reduces the sudden grabbing force that can cause kickback, improving safety and cutting accuracy across a range of wood and wood-composite materials.
How does this bit work with a cove bit for drop-leaf table joinery?
When a roundover and beading bit is used on one leaf edge and a cove bit is used on the mating edge, the two profiles nest together to form a rule joint - the traditional hinge joint used on drop-leaf tables and other folding furniture. The 1/4 in. radius on this bit is sized for pairing with a matching 1/4 in. cove bit for this application.
