Built from high-speed steel with a bright uncoated finish, this tool handles both operations without a tool change, making it a practical choice for machinists, fabricators, and trade professionals working with ferrous and non-ferrous materials. The body diameter measures 1\/4 inch with a 7\/64-inch point diameter and a 7\/64-inch point length. Overall length is 3 inches, classifying it as a long-length tool. The 118-degree drill point angle and 60-degree included angle are standard geometry for general-purpose center drilling and countersinking work.\u003c\/p\u003e\u003cp\u003eThis combo drill countersink is suited for production machining, job shop work, and maintenance repair operations where consistent countersink geometry is required. It is a right-hand cut tool in Series 185 with a plain cutting edge style and a double end type, allowing both ends to be used before the tool is retired. It applies to countersinking operations and is not an aircraft-style tool. Trade size is 3, which corresponds to the 1\/4-inch body diameter. Typical users include CNC machinists, manual lathe operators, and tool-and-die professionals working in shop environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCombination drill and countersink for single-pass operation  -  no tool change required\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction for durability across ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for general-purpose machining applications\u003c\/li\u003e\n\u003cli\u003eDouble-end design extends tool life by providing two usable cutting ends\u003c\/li\u003e\n\u003cli\u003e118-degree drill point angle with 60-degree included angle for standard countersink geometry\u003c\/li\u003e\n\u003cli\u003eLong-length tool at 3 inches overall length for added reach\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose OEM-style combo drill countersink for use in standard drill chucks and collets accepting a 1\/4-inch body diameter shank, compatible with manual lathes, milling machines, and CNC machining centers.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified machinists or trade professionals familiar with rotary cutting tools. Secure the tool firmly in an appropriate chuck or collet before operation and verify runout before cutting. Always power down and lock out the machine before changing or inspecting tooling.
