Hss Countersink Drills
Certificate:ISO9002,CE,GS,TUV
Material:HSS or M2

A Hss Countersink Drills 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 hex-headed capscrew.) 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.

 

Feature

• Made of high speed steel with good heat-treated, hardened and tempered for long time use.  
• 90 degree cone corresponds with the shape of the counter-sink screw or bolt head.  
• Radial back-off clearance makes it possible to work withour irattlingi, and also removes chipos and swarf perfectly. 
• Polish, Black Oxide & Titanium Coated are available.
