It features a 1\/2 inch head diameter with an 82-degree included angle, making it well suited for standard flat-head fastener seat preparation. The straight-cylindrical shank measures 6.35 mm in diameter and the tool has an overall length of 2.0 inches. An oxide coating helps reduce friction and provides basic surface protection during cutting. Right-hand cutting direction is standard for conventional drill press and hand-drill use.\u003c\/p\u003e\n\u003cp\u003eThis countersink is intended for use on alloy steel, cast iron, and tool steel workpieces in industrial maintenance, machine shop, and fabrication environments. It is a single-end tool with no pilot, which allows the operator to guide placement manually or with a fixture. Typical users include machinists, millwrights, and maintenance technicians working in shops or in the field. The 1\/2 inch maximum cutting diameter covers the most common flat-head screw sizes encountered in structural and mechanical assembly work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e82-degree included angle for standard flat-head fastener countersinking\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch head diameter and 1\/2 inch maximum cutting diameter\u003c\/li\u003e\n  \u003cli\u003eSingle flute geometry for clean, controlled material removal\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for use on alloy steel, cast iron, and tool steel\u003c\/li\u003e\n  \u003cli\u003eOxide coating reduces friction and provides surface protection\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank for compatibility with standard chuck styles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style countersink for use in standard drill presses, CNC machines, and hand drills accepting a straight-cylindrical shank.
