Countertop installers, this CMT flush trim bit is specifically designed for sink cutouts in solid surface materials! With a 3/4 inch diameter and 1/2 inch shank, it's built for precision work. You use it in combination with CMT's 880.572.11 overhang bit - first pass with the overhang bit cleans the cutout edge leaving a slight underside overhang, then this flush trim bit completes the operation for a perfect fit. The special super micrograin carbide lasts way longer than standard bits, so you get clean cuts through multiple jobs. It has a 1-inch cutting length and 3-5/64 inch overall length, giving you the reach needed for countertop work. If you're installing sinks in granite, quartz, or other solid surfaces, this professional-grade bit makes the difference between an okay installation and a perfect one. The carbide quality means you get smooth, chip-free edges every time. Definitely worth the investment if you do countertop work regularly - your sink installations will look factory-perfect!
