Built from high-speed steel with a titanium carbonitride (TiCN) finish, it delivers extended tool life and improved wear resistance in production and maintenance drilling applications. The tool features a 3\/8 inch body diameter, a 23\/64 inch drill point length, and a right-hand cutting direction with a plain cutting edge style. The 82-degree included angle suits standard flat-head fastener seating. Machinists, tooling technicians, and maintenance professionals use this style of combo tool to reduce setup steps and improve hole-to-countersink alignment.\u003c\/p\u003e\u003cp\u003eThis combo drill countersink is suited for use in machine shops, fabrication environments, and field maintenance settings where consistent countersink geometry is required. It is appropriate for use in drill presses, CNC machining centers, and handheld power tools when used with proper fixturing. The size 8 trade designation and 3\/8 inch body diameter make it compatible with standard countersink depths for number 8 flat-head fasteners in metal and hard plastic substrates.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHigh-speed steel construction with TiCN coating for extended wear resistance\u003c\/li\u003e\n\u003cli\u003e3\/8 inch body diameter sized for No. 8 flat-head fastener countersinks\u003c\/li\u003e\n\u003cli\u003e82-degree included angle for standard flat-head screw seating\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with plain cutting edge for clean, consistent results\u003c\/li\u003e\n\u003cli\u003e23\/64 inch drill point length and 1 inch overall length for compact tool reach\u003c\/li\u003e\n\u003cli\u003eSingle-end, non-tapered design with 7\/8 inch shank length\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard tooling addition for combo drill countersink applications requiring a size 8, 3\/8 inch body diameter tool in high-speed steel with TiCN finish.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tool is installed by machinists or tooling technicians into standard drill chucks or collet holders compatible with the shank diameter.
