Giga Selection Limited Carbide flat drill GSFDR2D-200

(1) Fully flat bottom blade
The 180-degree fully flat bottom cutting edge enables counterboring in a single step.
Furthermore, it can perform machining operations that were impossible with conventional drills, such as drilling holes in inclined surfaces and correcting eccentric holes.
It can also be expected to reduce burrs in thin sheets and toleranced holes.
(2) Special corner shape: The special corner shape helps prevent chipping and reduces burrs.
(3) Special surface treatment of the gash portion The surface of the gash portion at the bottom of the drill is specially treated to reduce friction with the workpiece and prevent built-up cutting edge.
(4) Optimized groove design: The optimized groove design achieves both excellent chip evacuation and vibration damping performance.
