Manufactured from cobalt high-speed steel and coated with titanium nitride (TiN), it delivers extended tool life in demanding threading applications. The bottoming chamfer style, with 1 to 1.5 chamfered threads, allows threading close to the bottom of a blind hole. Overall length is 3.3465 inches (85.70 mm) with a thread length of 0.8268 inches (21.00 mm). This tap belongs to the OSG HY-PRO NRT series and is suited for use by machinist and tool-and-die professionals in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis tap is rated for blind hole threading across a broad range of workpiece materials including alloy steel, carbon steel, die steel, hardened steel, stainless steel, and aluminum. The thread forming process displaces material rather than removing it, resulting in stronger formed threads and no chip evacuation concerns in blind holes. It is well suited for CNC machining centers and manual tapping operations where consistent 4H class-of-fit threads at a D6 thread limit are required. Right-hand thread direction is standard.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThread forming design produces chip-free M12x1.75 metric coarse threads in blind holes\u003c\/li\u003e\n  \u003cli\u003eCobalt high-speed steel construction provides heat and wear resistance in tough materials including hardened steel and stainless steel\u003c\/li\u003e\n  \u003cli\u003eTiN coating reduces friction and extends tool life across high-volume threading cycles\u003c\/li\u003e\n  \u003cli\u003eBottoming chamfer (1 to 1.5 threads) allows threading to near full depth in blind hole applications\u003c\/li\u003e\n  \u003cli\u003e4H class of fit with D6 thread limit ensures consistent, on-spec internal threads\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction; no coolant-through requirement simplifies machine setup\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for blind hole threading in alloy steel, carbon steel, die steel, hardened steel, stainless steel, and aluminum workpieces.

Ensure the spindle is properly aligned and the workpiece is securely fixtured before engaging the tap. For blind hole applications, set tapping depth stops carefully to avoid bottoming the tap under load. Use an appropriate tapping fluid or cutting oil compatible with the workpiece material to protect the tool and achieve on-spec thread finish.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M12x1.75\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Metric Coarse\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 4H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: D6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Bottoming\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfered Threads\u003c\/strong\u003e: 1 to 1.5P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Blind Hole Threading\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Alloy Steel, Aluminum, Carbon Steel, Die Steel, Hardened Steel, Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.3465 inches (85.70 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.8268 inches (21.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 1.9331 inches (49.10 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3670 inches (9.32 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.2756 inches (6.99 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 11.11 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HY-PRO NRT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.124 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: OSG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1410105405\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51732186300722,"sku":"1410105405","price":77.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a7374c814a10812df05fe66e8cea91a0.jpg?v=1788740177","url":"https:\/\/voomisupply.com\/products\/osg-1410105405-thread-forming-tap-m12x1-75-bottoming","provider":"Voomi Supply","version":"1.0","type":"link"}
