CMT High Quality Router Bits. The Perfect 10! Rated the #1 Overall Router Bits by Wood® Magazine. WHAT'S THE SECRET TO FLAWLESS EDGE PROFILES WITH NOW REWORK? SUPERIOR HIGH-STRENGTH STEEL: We use high-quality, solid bar stock sourced from Switzerland, which provides exceptional resistance to fatigue and abrasion. ANTI-KICKBACK DESIGN: Controls depth of cut and minimizes the chance of kickback, reducing your risk of injury. SINTERHIP HI-DENSITY INDUSTRIAL CHROME CARBIDE™: New process called SinterHIP (Hot Isostatic Pressing), helps prevent material failure and increases cutting life. TRI-METAL BRAZING: Our Silver-Copper-Silver brazing protects the carbide tip when cutting harder wood or wood composites 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 3x LONGER LASTING MIRROR FINISH: Each cutting edge is precisely sharpened to the micron, in order to produce a cutting angle, which is razor sharp, yet extremely durable.
