Product Description
CMT Flush Trim Router Bit with Double Bearing - 3/4" Diameter x 2" Cutting Height, 1/2" Shank is a precision-engineered trimming bit built for woodworkers who demand clean, accurate results on laminates, veneers, and template-guided cuts. Featuring a double-bearing guide system and a 2-flute hardwood-grade carbide construction, this flush trim bit delivers smooth, consistent edge results whether you are working on a handheld router, a router table, or a CNC routing machine. Designed for through mortises, pattern copying, and laminate trimming, it is a versatile addition to any routing setup that requires repeatable flush cuts against a template or adjacent surface.
Key Features
- Double bearing guide system - two ball bearings provide more stable contact with the template or workpiece edge, reducing bit wobble and improving cut consistency compared to single-bearing designs.
- 3/4" cutting diameter with 2" cutting height - handles deep cuts in a single pass through thicker stock, solid hardwood, plywood, MDF, laminates, and melamine without requiring multiple setups.
- 2-flute HW (hardwood-grade) carbide construction - the dual-flute geometry balances cutting speed and surface finish quality, leaving cleaner edges on both natural wood and engineered panels.
- -3 deg. cutting angle - the slight negative shear angle reduces tearout on laminates and veneers, preserving the integrity of thin face materials during flush trimming.
- 1/2" shank diameter - the larger shank transfers power more efficiently from the router collet, minimizing vibration and improving stability during extended template routing sessions.
- 4-5/16" total length - provides sufficient reach for deep template work and through mortise applications without requiring bit extensions.
- Right-hand (RH) rotation - compatible with the vast majority of standard handheld routers, router tables, and CNC routing machines for straightforward installation and use.
Why This Product
- The double bearing design gives woodworkers tighter template control on precision laminate work and pattern-copying tasks, directly addressing the common problem of bearing skip or chatter that causes out-of-flush cuts.
- With a full 2" cutting height and 3/4" diameter, this bit handles through mortises and deep flush-trim passes in one setup - eliminating the need to reposition the workpiece or swap to a larger bit mid-task.
- The -3 deg. cutting angle makes this bit particularly well suited for laminate and veneer trimming, where standard straight-angle bits can cause chipping or delamination at the edge.
- The 1/2" shank diameter reduces vibration during high-demand routing operations on harder materials, contributing to longer bit life and more consistent surface quality across the full cut.

Frequently Asked Questions
What makes this bit suitable for laminate trimming compared to standard flush trim bits?
This bit features a -3 deg. cutting angle, which reduces tearout and chipping along the edge of thin laminate and veneer surfaces. Combined with the double bearing guide for steady template tracking, it is specifically designed for precision work on laminates where a clean, tear-free edge is required.
Can this bit be used to cut through mortises?
Yes. CMT designed this flush trim bit series with through mortises as a stated application. The 2" cutting height provides enough reach to complete through mortise cuts in most standard workpiece thicknesses without needing a longer bit or a secondary pass.
What router collet size is needed to use this bit?
This bit has a 1/2" shank diameter, so it requires a router or router table equipped with a 1/2" collet. It is compatible with handheld routers, router tables, and CNC routing machines that accept a 1/2" collet.
Why does this bit have two bearings instead of one?
The double bearing configuration provides a wider, more stable contact point against the template or workpiece edge. This added stability reduces lateral movement during the cut, which translates to more consistent flush results - especially important during quick template work and on materials like laminates where any deviation is visible in the finished surface.
