Flute type determines how the bit removes chips and affects surface finish and feed rate. Common types include single and double flute, as well as up-shear, down-shear, and compression (up/down shear). Compression flutes are great for minimizing tear-out on laminated materials, while down-shear flutes push chips downward for a cleaner top surface. Products like the DRB-423 feature double flute down-shear for smooth plunging, and the DRB-192 uses compression up/down shear for superior edge quality. Multiple flute types are available, letting you choose the best option for your material and desired finish.
