Made from cobalt high-speed steel with a bright, uncoated finish, this tool handles tough materials including stainless steel and high-temperature alloys. The body measures 3\/16 inches in diameter with a 5\/64-inch drill point diameter and a 5\/64-inch drill point length. Overall length is 1-7\/8 inches. The 118-degree drill point angle and 60-degree included countersink angle are standard geometry for center drilling and countersinking operations in metalworking applications.\u003c\/p\u003e\u003cp\u003eThis combo drill countersink is suited for machine shops, maintenance facilities, and fabrication environments where accurate center drilling and countersinking are required before turning or milling operations. The double-end design extends tool life by providing two usable ends. Right-hand cut geometry is compatible with standard drill press, lathe, and CNC spindle rotation. The No. 2 trade size fits common center drill holder and collet setups used in production and job-shop environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt construction for improved heat and wear resistance in hard metals\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish for use across a wide range of metalworking materials\u003c\/li\u003e\n\u003cli\u003e118-degree drill point angle with 60-degree countersink included angle\u003c\/li\u003e\n\u003cli\u003eDouble-end design doubles usable tool life before replacement\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, plain cutting edge style for standard spindle rotation\u003c\/li\u003e\n\u003cli\u003eCompact 1-7\/8-inch overall length fits standard center drill holders and collets\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard tooling option for lathes, drill presses, and CNC machining centers that accept No. 2 trade size combination drill and countersink tooling.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or tooling technicians. Secure the tool in a compatible collet, chuck, or center drill holder rated for the 3\/16-inch body diameter before operation.
