Product Description
The CMT Flush Trim Bit - 3/4" x 2" with 1/2" Shank is a precision routing tool engineered for clean, accurate flush trimming against templates and adjacent surfaces. Built for woodworkers who demand consistent results, this bit excels at laminate trimming, template routing, and pattern copying on a wide range of materials. With a 2" cutting height and a 3/4" cutting diameter, it handles both through mortise work and surface trimming with equal confidence - making it a genuinely versatile addition to any router bit collection.
Key Features
- 3/4" Cutting Diameter x 2" Cutting Height - provides ample depth for through mortises and deep template passes, reducing the need for multiple routing stages.
- 1/2" Shank - fits standard 1/2" router collets found on most handheld routers, router tables, and CNC routing machines, offering a stable, vibration-reducing connection during operation.
- 2-Flute (2-Tooth) Design - balances cutting speed with surface finish quality, producing smooth edges on laminates, hardwoods, plywood, and composite materials.
- -3 deg. Cutting Angle - the negative shear angle is specifically suited to flush trim applications, helping to shear material cleanly at the surface without tearout or lifting.
- Right-Hand (RH) Rotation - compatible with the standard rotation direction of conventional routers and CNC spindles, ensuring straightforward setup with no special configuration required.
- 4-5/16" Total Length - extended overall length keeps the router collet clear of workpiece edges when working on thick stock or deep template setups.
- HW (Hard Metal / Carbide) Cutting Material - carbide construction maintains a sharp edge through repeated cuts on hardwoods, softwoods, laminates, melamine, and plastics, extending service life between sharpenings.
- Precision Template Following - designed to track accurately along a guide bearing or template surface, delivering repeatable profile copies and consistent flush results across multiple workpieces.
Why This Product
- A 2" cutting height gives this flush trim router bit the reach needed for through mortise work and deep template passes - tasks that shorter bits simply cannot complete in a single pass.
- The carbide (HW) construction means the cutting edges hold up through demanding sessions on laminates, hardwoods, and plastics without rapid dulling, reducing downtime and replacement costs.
- The -3 deg. cutting angle is purpose-tuned for flush trim work, helping the bit shear material cleanly at the surface rather than tearing it - a meaningful advantage when finishing laminate panels or veneered surfaces where tearout is unacceptable.
- With compatibility across handheld routers, router tables, and CNC routing machines, this bit adapts to the workflow of hobbyists, cabinetmakers, and production shops alike - making it a practical choice regardless of setup.

Frequently Asked Questions
What is the purpose of the -3 deg. cutting angle on this flush trim bit?
The -3 deg. cutting angle is a negative shear geometry that helps the bit shear material cleanly at the surface when flush trimming. This is particularly beneficial when working with laminates and veneered surfaces, where a clean, tear-free cut at the template line is critical to a finished result.
Can this bit be used on a router table as well as a handheld router?
Yes. The 1/2" shank and right-hand (RH) rotation of this flush trim bit are compatible with handheld routers, router tables, and CNC routing machines. The 1/2" shank in particular provides a rigid, stable connection that suits both freehand and table-mounted setups.
Is a 2" cutting height necessary for through mortise work?
According to CMT, the extended cutting height on this series is specifically noted as excellent for making through mortises. A 2" cutting height allows the bit to pass fully through thicker stock in a single routing operation, which is a meaningful advantage over shorter flush trim bits that may require multiple passes or repositioning.
What materials can this flush trim bit cut?
This bit is designed for precision work on laminates and for template work with excellent finishing results. The HW (carbide) cutting material makes it suitable for solid hardwoods, softwoods, plywood, MDF, laminates, melamine, and plastic - covering the full range of materials commonly encountered in woodworking and cabinetmaking applications.
