Built from cobalt high-speed steel with a bright, uncoated finish, it delivers durability in hard and abrasive materials. The tool carries a trade size of 8, a body diameter of 3\/4 inches, a drill point diameter of 3\/4 inches, and an overall length of 6 inches. The 118-degree drill point angle suits general-purpose drilling, while the 60-degree included angle on the countersink portion seats flat-head fasteners to standard specifications. Machinists, tool-and-die workers, and metalworking tradespeople are the primary users of this style of tool.\u003c\/p\u003e\u003cp\u003eThis combo drill countersink is suited for use in machine shops, fabrication environments, and maintenance applications where flat-head screws or rivets require a properly seated countersink. The plain cutting edge style and double end type make it a practical choice for production and repair work on ferrous and non-ferrous metals. The long-length designation at 6 inches overall allows access in deeper setups where standard-length tools fall short. It is not aircraft-style and does not use an insertable cutter head, keeping setup straightforward on drill presses, lathes, or milling machines.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt high-speed steel construction for use in hard and abrasive metals\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for general metalworking applications\u003c\/li\u003e\n\u003cli\u003e118-degree drill point angle for standard drilling entry\u003c\/li\u003e\n\u003cli\u003e60-degree included angle for countersinking flat-head fastener seats\u003c\/li\u003e\n\u003cli\u003eDouble end type extends tool life by providing two usable ends\u003c\/li\u003e\n\u003cli\u003eLong-length at 6 inches overall for reach in deeper setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard combo drill countersink for use with size 8 flat-head fasteners on drill presses, lathes, and milling machines in general metalworking and fabrication applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tool is installed and operated by machinists or metalworking tradespeople on powered machine tools.
