{"product_id":"5855-5-32-90","title":"Robet Charles Imperial Piloted Countersink - 3 Flutes Integral Pilot Straight Shank - 5\/32 Pilot Diameter - 90° Inclusive Angle","description":"\u003cdiv\u003e\n\u003cp\u003e\nThe Robet Charles Imperial piloted countersink is engineered for precise, repeatable countersinking in precision machining. With a 3-flute cutting design and an integral pilot, it delivers accurate hole alignment, smooth cutting action, and reduced chatter. The 90° inclusive angle supports consistent countersinks in a single operation, and the straight shank fits standard toolholders for reliable performance.\n\u003c\/p\u003e \u003cp\u003e\nDesigned for aerospace, automotive, and general engineering work, this countersink is manufactured to tight tolerances. The pilot diameter is held to −0.0005\" to −0.0015\", delivering concentric, repeatable results that help you achieve clean finishes and accurate seating.\n\u003c\/p\u003e \u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eIntegral pilot for precise alignment\u003c\/b\u003e: The built-in pilot centers the countersink on the hole, reducing wandering and ensuring concentric seating for reliable results.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003e3-flute design for smooth, efficient countersinking\u003c\/b\u003e: Three cutting edges provide stable cutting action and efficient chip evacuation, delivering clean, uniform finishes with reduced chatter.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eTight-tolerance pilot diameter with 90° countersink\u003c\/b\u003e: Pilot diameter held to −0.0005\" to −0.0015\" and a 90° countersink create repeatable depths and precise seating, ideal for critical assemblies.\u003c\/li\u003e\n\u003c\/ul\u003e \u003cp\u003e\nThis combination helps you streamline workflows by delivering repeatable, concentric countersinks with minimal chatter.
