Product Description
CMT Flush Trim Bit - 3/4" Diameter x 1-1/2" Cutting Height, 1/2" Shank is a professional-grade carbide-tipped router bit engineered for precision flush trimming, laminate work, and template routing. Designed by CMT for use in handheld routers, router tables, and CNC routing machines, this 2-flute right-hand rotation bit delivers clean, consistent results on a wide variety of materials - from solid hardwood and softwood to laminates, melamine, MDF, and plastics. Whether you are duplicating patterns with a template, trimming edge banding flush, or cutting through mortises, this bit provides the accuracy and finish quality that demanding woodworking applications require.
Key Features
- 3/4" cutting diameter with 1-1/2" cutting height - covers a generous surface area in a single pass, reducing the number of setups needed for flush trimming operations on thicker stock.
- 1/2" shank - provides a solid, secure connection to the router collet, minimizing vibration and deflection for straighter, smoother cuts.
- 2-flute carbide-tipped (HW) construction - tungsten carbide cutting edges stay sharp longer than high-speed steel and handle abrasive materials like laminates and MDF without premature dulling.
- -3 deg. cutting angle - the negative rake geometry reduces tearout and produces a cleaner shear on both natural wood grain and composite panel surfaces.
- Right-hand (RH) rotation - standard directional compatibility for use with conventional routers and CNC spindles, ensuring predictable feed direction and consistent results.
- 3-21/32" total length - gives adequate reach for template work and through-mortise cutting without sacrificing rigidity.
- Wide size range availability - part of a full series of flush trim bits in multiple sizes, so you can match the right tool to each specific application in your workflow.
- Optimized for precision laminate and template work - engineered specifically for finishing quality results on veneers, laminates, and pattern-guided cuts where surface quality matters.
Why This Product
- Designed for clean laminate and veneer trimming - the carbide-tipped edges and negative cutting angle work together to shear through delicate laminate surfaces without chipping or lifting the edge, giving you a professional finish right off the router.
- Template routing with consistent accuracy - the bit geometry and overall 3-21/32" length make it well suited for riding against a straight-edge or shaped template, reproducing patterns precisely and repeatedly across multiple workpieces.
- Capable of through mortise work - the 1-1/2" cutting height is sufficient for cutting through mortises, expanding the practical use of this bit beyond simple edge trimming to more structural joinery tasks.
- Part of an indispensable, purpose-built series - CMT developed this line specifically to address a wide range of woodworking scenarios, meaning the design decisions behind every dimension and geometry reflect real shop use - not general-purpose compromise.

Frequently Asked Questions
What materials can this flush trim bit cut?
This bit is designed for precision work on laminates, veneers, solid hardwood, softwood, plywood, MDF, chipboard, melamine, and plastic surfaces. The carbide-tipped (HW) cutting edges are durable enough to handle abrasive composite materials without rapid dulling.
What does the -3 deg. cutting angle mean for my cuts?
A negative cutting angle - in this case -3 deg. - means the flute geometry shears material with a slight backward rake. This reduces the tendency for tearout on delicate surfaces like laminates and veneer faces, producing a cleaner finished edge compared to bits with a neutral or positive rake angle.
Can this bit be used for template routing and through mortises?
Yes. CMT specifically engineered this flush trim series for precision template work and notes that these bits are excellent for making through mortises. The 1-1/2" cutting height provides enough depth to cut through standard stock thicknesses used in mortise applications, and the bit geometry follows a template edge accurately for consistent pattern duplication.
What machines are compatible with this 1/2" shank flush trim bit?
This bit accepts a 1/2" collet and is compatible with handheld routers equipped with a 1/2" collet, router tables, and CNC routing machines. Always confirm your router or CNC spindle accepts a 1/2" shank before use.
