Built from powdered metal with a TiCN coating, this tap delivers improved wear resistance and tool life compared to standard high-speed steel. The bottoming chamfer allows threading to the bottom of blind holes where spiral flute or plug taps cannot reach. With 4 flutes and an H5 thread limit, it holds tight tolerances suitable for precision fastener applications. Overall length is 3-5\/32 inches with a thread length of 1-7\/16 inches. Licensed machinists and toolroom technicians are the primary users.\u003c\/p\u003e\u003cp\u003eThis tap is suited for machine tapping operations in job shops, production facilities, and maintenance environments. It is engineered for use in aluminum and cast iron workpieces where chip control and surface finish matter. The straight flute geometry is best applied in through-hole or blind-hole applications where chips can be managed manually or with compressed air. Coolant-through capability is not included, so adequate flood or mist coolant delivery from the machine is recommended when tapping cast iron or harder aluminum alloys. The Series 10052 designation places this tap within OSG's standard machine tap line.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBottoming chamfer for threading to the bottom of blind holes\u003c\/li\u003e\n\u003cli\u003ePowdered metal construction with TiCN coating for extended tool life\u003c\/li\u003e\n\u003cli\u003e4 straight flutes with H5 thread limit for consistent tolerance control\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction, 7\/16-14 UNC thread form\u003c\/li\u003e\n\u003cli\u003eRated for aluminum and cast iron material applications\u003c\/li\u003e\n\u003cli\u003eNo coolant-through design — compatible with external flood or mist coolant setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for machine tapping of 7\/16-14 UNC right-hand threads in aluminum and cast iron workpieces.
