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;
Specification of HSS Countersink
* 60 degrees, grade 75, 82 degrees and 120 degrees are available.
* 3 ends cutting
* Best result at low cutting speed.
* Speed and precision of the hob, removing burrs and chamfer in any materialesincluding iron, steel, plastic or wood.
* M35 % HSSCo5 (HSS-E) available to specified requirements
* Surface finish: white, black, titanium coated and aluminum Nitride coated are
* Packaging: Individual packing in plastic or plastic blister
