Why CBN-ground flutes?

CBN(Cubical Boron Nitride) is a much harder abrasive than even silicon carbide or corundum, a better and sharper cutting edge is achieved without burrs.
With such higher dimensional precision, the drill bits will last considerably longer while maintaining precise process tolerances.

What is countersink?

A countersink is a conical hole cut into a manufactured object; a countersink bit (sometimes called simply countersink) is the cutter used to cut such a hole. A common use is to allow the head of a bolt or screw, with a shape exactly matching the countersink hole, to sit flush with or below the surface of the surrounding material.
A countersink may also be used to remove the burr left from a drilling or tapping operation thereby improving the finish of the product and removing any hazardous sharp edges.
A countersink may be used in many tools, such as drills, drill presses, milling machines and lathes.
