It cuts an M8x1.25 thread to a 6H class of fit with a D5 thread limit, making it suitable for close-tolerance work. The tap is manufactured from cobalt high-speed steel and carries an oxide finish for improved lubricity and wear resistance. With a 40-degree helix angle and a fast flute style, it evacuates chips efficiently out of the hole during the tapping cycle. Overall length is 90 millimeters with a thread length of 14 millimeters and a tapping depth of 35 millimeters. Licensed HVAC techs, machinists, and toolroom professionals specify this geometry for through-spindle or hand-tapping setups where chip packing is a concern.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for blind hole threading across a wide range of ferrous and non-ferrous materials. The modified bottoming chamfer allows threading closer to the bottom of a blind hole than a plug chamfer, which is useful in tight-clearance assemblies. The right-hand flute and right-hand thread configuration covers the most common production and maintenance tapping scenarios. Applicable materials include alloy steel, alloy tool steel, aluminum alloy, case-hardened steel, cast iron, ductile iron, free-cutting steel, heat-treated steel, malleable cast iron, stainless steel, structural steel, and tool steel.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM8x1.25 metric thread, 6H class of fit, D5 thread limit for close-tolerance blind hole work\u003c\/li\u003e\n  \u003cli\u003eCobalt HSS construction provides heat and wear resistance in tough materials including stainless and heat-treated steel\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle with fast flute style promotes efficient upward chip evacuation in blind holes\u003c\/li\u003e\n  \u003cli\u003eModified bottoming chamfer allows threading nearer to the bottom of a blind hole than a standard plug tap\u003c\/li\u003e\n  \u003cli\u003eOxide finish improves surface lubricity and reduces galling during the cut\u003c\/li\u003e\n  \u003cli\u003eRight-hand flute and right-hand thread for standard CNC and hand-tapping applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard M8x1.25 tapping applications across the listed material types including alloy steel, aluminum alloy, stainless steel, cast iron, and related ferrous and non-ferrous workpiece materials.

Power down or lock out the machine before changing tooling. Use appropriate tapping fluid for the workpiece material, particularly when tapping stainless or heat-treated steel. Verify blind hole depth against the 35.00 millimeter tapping depth before beginning the cycle to avoid bottoming out under load.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M8x1.25\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Metric\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 6H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: D5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Modified Bottoming\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Style\u003c\/strong\u003e: Fast\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt HSS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Blind Hole Threading\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 14.00 millimeters (0.5512 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 35.00 millimeters (1.3780 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 90.00 millimeters (3.5433 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 8.00 millimeters (0.3150 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.8268 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 6.20 millimeters\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Pitch\u003c\/strong\u003e: 1.25 millimeters\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: 5734\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.07 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: GUHRING\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9057340080000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51730153931058,"sku":"9057340080000","price":37.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/21113fe9ecc6600f5ae5916aef84ff1d.jpg?v=1788712673","url":"https:\/\/voomisupply.com\/products\/guhring-9057340080000-spiral-flute-tap-m8x1-25-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
