Product Description
CMT Chamfer Router Bit with Insert Knives - 63/64" Diameter, 22 deg. Angle, 1/4" Shank is a precision bevel and chamfer trim bit designed for exacting edge work on hardwood, MDF, laminates, and more. Featuring two replaceable insert knives secured by special Torx screws, this right-hand rotation bit delivers clean, repeatable 22 deg. chamfers on decorative edges and profiles. The integrated ball bearing guide keeps every cut consistent and accurate without the need for counter-profiles, making it equally well-suited for use on portable routers and CNC machining centers. For woodworkers and production shops that demand economy and precision in a single tool, this CMT chamfer bit with replaceable tips is a smart, cost-effective choice.
Key Features
- Two Replaceable Insert Knives - each knife is sharpened on all 4 sides and provides three additional new cutting edges, dramatically reducing tooling cost per job and extending the useful life of the bit assembly.
- Special Torx Screw Fastening - secures the insert knives firmly in place during operation, ensuring consistent chamfer geometry and safe performance at routing speeds.
- Ball Bearing Guide (Type 659) - eliminates the need for counter-profiles by riding along the workpiece edge, delivering a uniform 22 deg. bevel every pass without manual depth adjustments.
- 22 deg. Chamfer Angle - produces a precise, shallow bevel ideal for decorative edgework, assembly chamfers, and profile work across a wide range of materials.
- 63/64" Cutting Diameter with 7/16" Cutting Height - sized for clean, full-contact passes on edge profiles in hardwood, softwood, MDF, laminates, and similar sheet materials.
- 1/4" Shank - fits standard 1/4" collets on portable handheld routers and router tables, providing broad compatibility with common workshop tooling.
- Right-Hand Rotation - engineered for standard router spindle direction, ensuring safe engagement with the workpiece and smooth chip ejection.
- HW (Hardmetal/Carbide) Material - insert knives made from hard metal deliver durability and edge retention suited for precision work on laminates and hard wood.
Why This Product
- Economy through replaceable tips - instead of replacing the entire bit when an edge dulls, each of the two insert knives offers up to four usable cutting edges (all 4 sides sharpened), making this chamfer bit a cost-effective solution for specialist applications and high-volume production environments.
- Bearing-guided accuracy without extra setup - the ball bearing guide built into the Type 659 design keeps the chamfer consistent along the full length of any edge, eliminating counter-profile fixtures and reducing setup time for decorative edgework and bevel trimming.
- Versatile material compatibility - the hard metal insert knives are specifically recommended for precision work on laminates, MDF, and quick rounded or beveled edges in hard wood, covering a wide range of common furniture and millwork applications.
- Portable router and CNC-ready - the 1/4" shank and right-hand rotation design make this bit compatible with both handheld portable routers and CNC machining centers, giving it flexibility across shop and production environments.

Frequently Asked Questions
Can the insert knives in this chamfer bit be replaced or resharpened?
Yes. The bit uses two replaceable insert knives that are sharpened on all 4 sides, providing three extra new cutting edges beyond the first. When one edge dulls, the knife can be rotated or replaced rather than discarding the entire bit, keeping tooling costs down for ongoing chamfer and bevel work.
Does this bit require a counter-profile or template to guide the cut?
No. The Type 659 design includes a ball bearing guide that rides along the workpiece edge, maintaining consistent chamfer depth and angle throughout the cut. This eliminates the need for counter-profiles and simplifies setup for both production runs and one-off decorative edgework.
What routers and machines is this bit compatible with?
The 1/4" shank fits standard 1/4" collets on portable handheld routers and router tables. The bit is also suitable for use on CNC machining centers. It is designed for right-hand rotation, which is standard on most router spindles.
What materials can this 22 deg. chamfer bit cut?
The hard metal insert knives are recommended for precision work on laminates, MDF, and hard wood. The bit is also suited for softwood, making it a versatile choice for furniture making, millwork, and panel processing applications where a clean 22 deg. bevel or chamfer edge is required.
