Built from vanadium high-speed steel and finished with an oxide coating, this tap handles the elevated heat and wear demands of tapping stainless steel and other tough materials. The spiral point geometry pushes chips forward ahead of the cut, keeping the flutes clear and reducing the risk of chip packing in through-hole applications. With 3 flutes and a D6 thread limit, it delivers consistent thread accuracy suitable for close-tolerance work. Machinists and tool crib technicians in metalworking shops are the primary users of this tap.\u003c\/p\u003e\u003cp\u003eThis tap is suited for through-hole tapping operations in stainless steel, as indicated by its material application rating. The plug chamfer provides a gradual lead-in that distributes cutting forces across several threads, making it a practical choice for CNC machining centers and manual drill presses alike. The right-hand thread direction matches standard fastener orientation for most industrial assemblies. Coolant-through capability is not available on this tap, so external flood or mist coolant should be applied when tapping stainless steel to control heat buildup and extend tool life.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM16x1.50 thread size with a D6 thread limit for consistent close-tolerance threading\u003c\/li\u003e\n\u003cli\u003eVanadium high-speed steel construction resists heat and wear in difficult materials\u003c\/li\u003e\n\u003cli\u003eOxide coating reduces friction and provides basic corrosion resistance\u003c\/li\u003e\n\u003cli\u003eSpiral point geometry pushes chips forward, optimized for through-hole applications\u003c\/li\u003e\n\u003cli\u003ePlug chamfer (approximately 3-5 thread lead-in) eases entry and distributes cutting load\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction for standard fastener compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in through-hole tapping of stainless steel workpieces requiring an M16x1.50 metric thread.

Always secure the workpiece and ensure the spindle is stopped before changing tooling. Apply adequate external coolant or cutting fluid when tapping stainless steel to prevent galling and premature tool failure. Do not exceed the recommended feed rate for the tap size, and back off periodically to break chips if performing manual tapping.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M16x1.50\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Style\u003c\/strong\u003e: Plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: D6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Vanadium High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating \/ Finish\u003c\/strong\u003e: Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 97 mm (approximately 3.82 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 32 mm (approximately 1.26 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 12.19 mm (approximately 0.48 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 2.5 inches (L) x 0.5 inches (W) x 0.5 inches (H)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: T1630616\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51735274389810,"sku":"T1630616","price":132.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c1006ffffef5de1ca29f7fae0667563e.jpg?v=1788771371","url":"https:\/\/voomisupply.com\/products\/accupro-t1630616-spiral-point-tap-m16x1-50-3-flutes","provider":"Voomi Supply","version":"1.0","type":"link"}
