Built from high speed steel with an oxide coating, it delivers controlled cutting action through a 100-degree included angle geometry. The 1\/2-inch head diameter and 1\/4-inch straight cylindrical shank make it a compact, purpose-built tool for countersinking fastener seats to spec. Right-hand cutting direction suits standard drill press and hand-drill setups. Machinists, fabricators, and maintenance technicians working in metal shops, job sites, and production environments reach for this type of tool when consistent countersink geometry is required.\u003c\/p\u003e\n\u003cp\u003eThis countersink is suited for use in carbon steel and cast iron applications where a 100-degree seat angle is required. The single-flute design reduces chatter and produces a cleaner finish on softer ferrous materials. It fits standard drill chucks and collet holders accepting a 1\/4-inch shank. No pilot is included, so it relies on an existing drilled hole for centering. Typical use cases include fastener seat preparation, edge chamfering, and deburring on flat or near-flat workpiece surfaces in light manufacturing and maintenance-repair settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2-inch head diameter with 100-degree included angle for standard fastener seat geometry\u003c\/li\u003e\n  \u003cli\u003eSingle-flute design minimizes chatter on ferrous materials\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction provides wear resistance across extended use cycles\u003c\/li\u003e\n  \u003cli\u003eOxide coating reduces friction and helps protect the cutting edge\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch straight cylindrical shank fits common drill chucks and collet holders\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction compatible with standard rotary tooling setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for countersinking operations in carbon steel and cast iron.
