It carries a 1\/2-13 UNC thread form with a modified bottoming chamfer, allowing threads to be cut close to the bottom of a blind hole. The tap is manufactured from powdered metal and finished with a TiN coating to extend tool life and reduce friction in tough alloys. At 3.381 inches overall length with a 40-degree helix angle, it is well suited for fast chip evacuation in deep or interrupted cuts. Installation is performed by licensed machinists or toolroom technicians in CNC or manual tapping operations.\u003c\/p\u003e\n\u003cp\u003eThis tap is applied in blind hole threading operations where access to aerospace alloys and stainless steel requires aggressive chip removal. The fast flute style and 40-degree helix angle pull chips up and out of the hole efficiently, reducing the risk of chip packing. The 2B class of fit and H5\/H6 thread limit ensure the finished thread meets standard tolerance requirements for interchangeable fastener applications. It is a single-piece tool sold individually and is appropriate for production environments where consistent thread quality in difficult materials is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eModified bottoming chamfer for threading close to the bottom of blind holes\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle with fast flute style for efficient chip evacuation in aerospace alloys and stainless steel\u003c\/li\u003e\n  \u003cli\u003eTiN coating reduces friction and extends tool life in abrasive materials\u003c\/li\u003e\n  \u003cli\u003ePowdered metal construction provides improved wear resistance over standard HSS\u003c\/li\u003e\n  \u003cli\u003e2B class of fit with H5\/H6 thread limit for standard interchangeable thread tolerance\u003c\/li\u003e\n  \u003cli\u003eRight-hand flute and right-hand thread, no coolant-through requirement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for use in aerospace alloy and stainless steel workpiece materials.
