Product Description
CMT Flush Trim Bit - 3/4" Diameter x 1" Cutting Height, 1/4" Shank by CMT is a precision routing bit engineered for flush trimming laminates, veneers, and solid wood surfaces to a template or adjacent surface. With a 2-tooth carbide-tipped design and a right-hand rotation, this bit delivers clean, accurate results whether you are pattern routing on a router table, trimming plastic edging, or creating through mortises in a workpiece. The 1/4" shank makes it compatible with a wide range of handheld routers and router tables, while the -5 deg. cutting angle helps produce smooth, chip-free edges on demanding materials.
Key Features
- 3/4" Cutting Diameter - sized to trace templates cleanly and remove material efficiently without deflection, making it ideal for flush trimming laminates and pattern work.
- 1" Cutting Height - provides full engagement with workpieces up to 1" thick, so you can trim edge banding, laminates, and veneers in a single pass.
- -5 deg. Cutting Angle - the slightly negative shear angle reduces tearout and produces a smoother finish on laminates, melamine, and solid hardwood surfaces.
- 2-Flute HW (Carbide) Construction - two cutting edges extend tool life and help balance heat dissipation, keeping the bit running cool during repetitive template or laminate trimming operations.
- 1/4" Shank - fits the majority of handheld routers and compact router tables, giving this bit broad compatibility across common workshop setups.
- Right-Hand Rotation - standard RH rotation works with conventional router motor direction, requiring no special setup or collet adapters.
- 2-29/32" Total Length - long enough to seat securely in the collet while still providing adequate clearance above the workpiece for template work and pattern copying.
- Designed for Precision Laminate and Template Work - engineered specifically for finish-quality trimming on laminates and quick template routing, as well as making through mortises, reducing the need for secondary sanding or hand-fitting.
Why This Product
- The -5 deg. cutting angle and 2-flute HW carbide design work together to minimize tearout on laminates and melamine - materials that commonly chip with lesser bits - giving you cleaner edges straight off the router.
- At 1" of cutting height, this bit handles full-thickness laminate panels and edge banding in one pass rather than requiring multiple setups, saving time on production and cabinetry work.
- The 1/4" shank broadens compatibility to include compact trim routers and standard routers alike, so this single bit fits multiple machines in the same shop without adapters.
- CMT designed this series specifically for precision work on laminates and quick template routing as well as through mortises, meaning the geometry is purpose-built for these demanding applications rather than adapted from a general-purpose profile.

Frequently Asked Questions
What is the purpose of the -5 deg. cutting angle on this flush trim bit?
The -5 deg. cutting angle creates a slight shear action as the flutes engage the material. This reduces the tendency for laminates, melamine, and hardwood veneers to chip or tear along the cut edge, resulting in a smoother surface finish that requires less sanding or hand cleanup after routing.
Can this bit be used for making through mortises?
Yes. CMT designed this series of flush trim bits to be excellent for making through mortises in addition to standard laminate trimming and template routing work. The 1" cutting height and 2-flute carbide construction support controlled plunge and trim operations in solid wood and panel materials.
What types of routers accept a 1/4" shank bit?
A 1/4" shank is one of the most common collet sizes and is accepted by the vast majority of handheld trim routers, mid-size routers, and many router table setups. Always confirm your router's collet size before installing any bit, and ensure the collet is properly tightened to the manufacturer's specification before operating.
How many flutes does this flush trim bit have, and why does that matter?
This bit has 2 flutes (teeth). A 2-flute design provides a balance between chip clearance and cutting frequency - each flute takes a defined chip load per rotation, which helps maintain a consistent feed rate during laminate trimming and template routing without overloading the router motor.
