WDX260D5S32 Special Flute Shape for L/D=5 * Designed with emphasis on chip evacuation Expanded flute design improves chip evacuation for stable drilling performance even with holes up to 5 L/D.
Amplitude in the thrust direction is larger than flutes designed for up to 4 L/D, but drilling performance is stable even when drilling deep holes of 5 L/D.
