Built to trade size 3 with a 1\/4 inch body diameter, it features a 7\/64 inch drill point diameter and a 60-degree included angle suited for precise countersinking work. The bright, uncoated finish is standard for solid carbide tooling where coating is not required. At 2 inches overall length, this is a compact, rigid tool for controlled, accurate entry. It is installed by machinists, tool and die workers, and fabrication technicians working in metal or composite materials.\u003c\/p\u003e\u003cp\u003eThis combo drill countersink is appropriate for countersinking applications in production machining, fabrication shops, and maintenance environments. The double-end type and plain cutting edge style make it a practical choice for standard countersink prep on fastener holes. Right-hand cut orientation is the conventional direction for most drilling operations. This tool is not an aircraft-style design and is not a long-length tool, making it best suited for standard-depth countersinking tasks at typical workpiece access.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard materials\u003c\/li\u003e\n\u003cli\u003eCombo drill and countersink in a single tool pass\u003c\/li\u003e\n\u003cli\u003e60-degree included angle for standard countersink geometry\u003c\/li\u003e\n\u003cli\u003e7\/64 inch drill point diameter and 7\/64 inch drill point length\u003c\/li\u003e\n\u003cli\u003eDouble-end type extends tool life by providing two usable ends\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish  -  no coating to chip or peel during operation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose combo drill countersink for standard countersinking applications; confirm spindle chuck capacity accepts a 1\/4 inch body diameter shank before use.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tool is installed in a drill press, CNC machining center, or hand drill with an appropriate chuck. Ensure the machine is powered down and the spindle is fully stopped before inserting or removing the tool. Secure the workpiece firmly before beginning the operation to prevent movement during cutting.
