HSS COUNTERSINK 

A countersink is a conical hole cut into a manufactured object, or the cutter used to cut such a hole.
A common use is to allow the head of a countersunk bolt or screw, when placed in the hole, to sit flush with or below the surface of the surrounding material (by comparison, a counterbore makes a flat-bottomed hole that might be used with a socket-head screw).
 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.


Fetures of HSS countersink
1. Ideal for chatter-free and burr-free work on sheet metal, nonferrous metal, cast iron, light metals;
2. It's designed for fast shearing and chatterless cuts;
3. It's with an exceptionally fine finish and can be run at maximum speed;
4. The cutting edges quickly center in hole and produce a smaller chip load for chatterless machining;
