With a 3\/16 inch head diameter and an 82-degree included angle, this countersink is sized for standard flat-head fastener preparation in light-duty and precision drilling applications. The straight cylindrical shank allows it to seat directly in standard drill chucks without adapters. High speed steel construction provides adequate hardness for general-purpose countersinking on ferrous and non-ferrous workpieces. Machinists, tool and die technicians, and maintenance professionals use this style of countersink for deburring, chamfering, and fastener seat prep on production and repair work.\u003c\/p\u003e\n\u003cp\u003eThis countersink is suited for bench drill press, hand drill, and CNC spindle use where a compact 3\/16 inch diameter tool is required. The 82-degree included angle matches the seating geometry of standard imperial flat-head screws commonly used in sheet metal and light structural assemblies. The single-flute design reduces chatter on softer materials and simplifies sharpening in the field. It is an appropriate choice for maintenance shops, fabrication environments, and precision assembly operations requiring consistent countersink geometry at a small diameter.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/16 inch head diameter for compact, precise countersinking in tight locations\u003c\/li\u003e\n  \u003cli\u003e82-degree included angle matches standard flat-head fastener seating geometry\u003c\/li\u003e\n  \u003cli\u003eSingle-flute design minimizes chatter and simplifies field resharpening\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction handles ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank seats directly in standard drill chucks without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use countersink for standard drill press chucks, hand drills, and CNC spindles accepting a 3\/16 inch straight cylindrical shank tool.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a standard drill chuck rated for the shank diameter.
