Product Description
The CMT 807.190.11 3-In-1 Flush Trim Bit for MDF and Laminate is a precision router bit engineered for clean, chip-free edge trimming on plastic laminates, aluminium laminates, and MDF. With a 3/4" cutting diameter and a 1/4" shank, this bit fits compact handheld routers and router tables alike, making it a versatile choice for cabinetmakers, countertop fabricators, and woodworkers who demand a finished edge without the need for secondary filing or sanding. The shear angle cutting geometry delivers smooth results on demanding composite materials where conventional bits often leave ragged or fibrous edges.
Key Features
- 3-in-1 Bit Design - handles multiple flush trimming tasks in a single bit profile, reducing the need to swap tooling mid-project and saving setup time on laminate and MDF work.
- Shear Angle Cutting Edge - slices through material at an angle rather than a perpendicular bite, which significantly reduces the need for filing and leaves a cleaner finished edge on plastic laminates and aluminium laminates.
- 2-Flute Configuration - dual cutting edges balance feed rate and finish quality, providing smooth chip evacuation and a consistent edge profile on MDF and laminate surfaces.
- HW (Tungsten Carbide) Cutting Material - hard-wearing carbide construction maintains a sharp cutting edge longer than high-speed steel alternatives, extending service life on abrasive composite materials like MDF and plastic laminate.
- 1/4" Shank Diameter - compatible with a wide range of compact routers and laminate trimmers, making this bit accessible for both job-site and shop use without requiring a full-size router.
- Right-Hand Rotation - standard RH rotation works with all conventional routers and router tables without any special spindle configuration.
- Compact Total Length of 2 11/32" - the short overall length keeps the bit rigid and reduces vibration during cutting, contributing to a cleaner, more controlled finish.
Why This Product
- Purpose-built for plastic and aluminium laminates as well as MDF - materials that are notoriously prone to chipping and fraying with standard flush trim bits - the shear angle geometry addresses those exact failure modes directly.
- The 3-in-1 functionality means one bit covers flush trimming applications that might otherwise require multiple separate bits, keeping tooling costs lower and the router table organized.
- At 5/8" cutting height paired with a 3/4" diameter, this bit is sized for the precise overlap needed in laminate countertop and edge-banding work where accuracy and a clean finished surface are critical.
- The 1/4" shank makes this bit compatible with lightweight laminate trimmers as well as full router tables and CNC routing machines, giving it genuine versatility across different shop setups and job-site conditions.

Frequently Asked Questions
What does "3-in-1" mean for this flush trim bit?
The 3-in-1 designation refers to the bit's ability to perform multiple flush trimming functions in a single profile. This means fewer tool changes during laminate and MDF edge-finishing work, making the bit particularly efficient for plastic laminate and aluminium laminate applications.
Why is this bit recommended specifically for MDF and laminate rather than solid wood?
MDF and plastic or aluminium laminates are highly abrasive and prone to chipping when cut with standard geometry bits. The shear angle cutting edge on this bit slices through those materials more cleanly, reducing the need for filing after the cut - which is a common requirement when using conventional flush trim bits on these surfaces.
What routers or machines are compatible with this bit?
The 1/4" shank fits a wide range of handheld routers, laminate trimmers, router tables, and CNC routing machines that accept a 1/4" collet. The right-hand rotation is standard for all conventional router setups.
How does the shear angle cutting edge reduce filing?
Rather than cutting perpendicular to the material, the shear angle slices across the surface fibers or laminate layers at a diagonal. This shearing action produces a cleaner, smoother edge in a single pass, reducing or eliminating the secondary filing step that is otherwise typical when trimming plastic laminate or MDF edges.
