CMT Replaceable Carbide Insert Flush Trim Bits with Bottom Bearing Guide
These CMT carbide insert router bits are the best we offer. You’ll never need to replace or sharpen an entire bit again. When the inserts get dull, simply rotate them a quarter turn, tighten them back down, and get right back to work. After routing countless miles of wood, when all four edges of the inserts are dulled, just order a new set of inserts, and you’re back in business. The convenience of carbide insert router bits eliminates the hassle and expense of resharpening.
The cutting edges, or inserts, can be replaced individually when they become dull or damaged, eliminating the need to replace the entire bit and significantly reducing long-term costs. Changing the inserts is quick and easy, minimizing downtime and letting you stay focused on your work.
Unlike brazed bits, which require professional sharpening and can alter the bit’s diameter, insert bits maintain their original profile. This ensures that when you rotate or replace an insert, the bit retains its precise geometry, delivering consistent and accurate cuts throughout its lifespan.
These bits also use high-quality, specialized carbide grades designed specifically for insert applications. This makes the cutting edges more durable and efficient, outperforming the carbide used in brazed bits. Additionally, because the inserts aren’t permanently attached to the tool body, they dissipate heat more effectively. This reduces the risk of thermal damage and premature dulling, keeping the cutting edges sharper for longer.
CMT carbide insert router bits are the ultimate solution for woodworkers who value reliability, efficiency, performance, and long-term cost savings.

CMT carbide tipped router bits produce flawless profiles due to the following features:
SUPERIOR HIGH STRENGTH STEEL BODIES: CMT uses only high-quality, solid bar stock sourced from Switzerland, which provides exceptional resistance to fatigue and abrasion. Larger diameter bodies are heat forged before turning into precise bit bodies. This extra step produces a radial grain orientation which offers large diameter bits extra strength and durability. All machining fully automated ensuring the shanks and bodies are accurate and perfectly balanced.
ANTI-KICKBACK DESIGN: This design controls the depth of cut and minimizes the chance of kickback, reducing your risk of injury.
SINTERHIP HI-DENSITY INDUSTRIAL CHROME CARBIDE: CMT uses specially formulating chrome carbide specially designed to cut wood and laminates. A new process called SinterHIP (Hot Isostatic Pressing), helps prevent material failure and increases cutting life.
TRI-METAL BRAZING: CMTs silver-copper-silver brazing “sandwich” provides a tight bond between the steel and the carbide, with a shock absorbing effect to protect the carbide tips when cutting harder woods and reduces the chance of failed welds.
NON-STICK ORANGE SHIELD COATING®: Prevents bit from heating up, reduces pitch build-up, protects against corrosion, and provides a longer bit life.
MULTI-AXIS GRINDING CREATES A MIRROR FINISH LASTING 3X LONGER: Sharpening is done to extreme precision on multi-axis CNC machines. Each bevel and angle are ground or sharpened to the micron, to produce a cutting edge that is both razor sharp, yet extremely durable.
