The number of flutes affects chip evacuation, surface finish, and feed rate. Fewer flutes (such as 2-flute bits like the 1/8" Solid Carbide CNC Foam Cutting Up-Cut Square End Spiral) provide better chip clearance and are great for softer materials or high-speed cutting. More flutes (like 3-flute bits such as the CNC Solid Carbide Mortise Compression Spiral) yield smoother finishes and are suitable for harder materials. The product selection includes both 2 and 3-flute options, allowing you to select the best bit for your desired finish and material type.
