Built from 3% vanadium high speed steel with an oxide finish, it delivers improved wear resistance and lubricity compared to standard HSS taps. The three-flute spiral point design pushes chips forward ahead of the cutting zone, making it well suited for through-hole tapping. With an overall length of 69 millimeters and a thread length of 22 millimeters, this tap fits standard tap holders and is sized for use on CNC machining centers, drill presses, and manual tapping operations. The D4 thread limit provides the tolerance control required for precision threaded fastener fits.\u003c\/p\u003e\u003cp\u003eThis tap is optimized for use in stainless steel, a material that demands sharper cutting geometry and higher alloy tooling due to its work-hardening characteristics. The plug chamfer — typically 3 to 5 threads of lead — allows the tap to self-start in a pre-drilled hole and is the standard choice for most through-hole production tapping. It is appropriate for both horizontal and vertical tapping setups in job shop, production, and maintenance environments. Right-hand thread direction matches standard M8 x 1 fastener specifications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM8 x 1 thread size, right-hand direction\u003c\/li\u003e\n\u003cli\u003e3% vanadium HSS construction for extended tool life in stainless steel\u003c\/li\u003e\n\u003cli\u003eOxide finish improves lubricity and reduces galling\u003c\/li\u003e\n\u003cli\u003eSpiral point geometry pushes chips forward for clean through-hole threading\u003c\/li\u003e\n\u003cli\u003eD4 thread limit for controlled tolerance fits\u003c\/li\u003e\n\u003cli\u003ePlug chamfer for easy starting in pre-drilled through holes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eRated for use in stainless steel workpieces.

Ensure the workpiece is securely fixtured and the pre-drilled hole meets the correct tap drill diameter for M8 x 1 before starting. Apply cutting fluid rated for stainless steel to reduce heat buildup and extend tap life. Do not reverse the tap under power without a reversing tap head or CNC canned cycle to avoid breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M8 x 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Type\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: D4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: 3% 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\u003eOverall Length\u003c\/strong\u003e: 69 millimeters\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 22 millimeters\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 8.08 millimeters\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\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: T1630374\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51727158378802,"sku":"T1630374","price":54.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d7ed50efe127a58b8cc67dda25ca2315.jpg?v=1788674135","url":"https:\/\/voomisupply.com\/products\/accupro-t1630374-spiral-point-tap-m8-x-1-plug-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
