💡 How does a negative rake angle improve cleanup when machining soft foam? You get smoother edges because the cutting lips shear the material upward before it hits the bit. - Downcut flute design traps dust particles below the workpiece level - Solid carbide composition resists heat buildup during continuous runs - Square end profile allows you to plunge straight into deadstop areas safely
