Built from high-speed steel with a bright polished finish, it delivers consistent, clean entry angles without chatter. The adjustable stop collar allows the operator to set a repeatable countersink depth, reducing rework on high-volume or close-tolerance jobs. The integral pilot keeps the tool centered in the existing hole for accurate seating. Overall length is 2.5 inches with a 0.5-inch head diameter and a 100-degree included angle, making it suited for flat or flush fastener seating.\u003c\/p\u003e\u003cp\u003eThis countersink fits production and job-shop environments where repeated, controlled countersink depth is required. The 3\/16-inch pilot diameter and 1\/4-28 straight threaded shank make it compatible with standard adjustable-stop countersink holders. With a 1.75-inch shank length and 3\/16-inch shank diameter, it seats securely in compatible toolholders. Machinists, tool-and-die technicians, and sheet metal fabricators working on ferrous and non-ferrous materials will find this tool appropriate for standard countersinking operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAdjustable stop collar for repeatable, controlled countersink depth\u003c\/li\u003e\n\u003cli\u003eIntegral pilot for self-centering alignment in pre-drilled holes\u003c\/li\u003e\n\u003cli\u003e2-flute geometry provides clean cutting action and chip clearance\u003c\/li\u003e\n\u003cli\u003e100-degree included angle for flat-head fastener seating\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction with bright polished coating\u003c\/li\u003e\n\u003cli\u003e1\/4-28 straight threaded shank for use with standard adjustable-stop holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard adjustable-stop countersink holders accepting a 1\/4-28 straight threaded shank with a 3\/16-inch shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by a qualified machinist or fabrication technician.
