Built from high speed steel with a bright uncoated finish, it delivers consistent thread form across a range of workpiece materials. The 4-flute straight flute design channels chips effectively during hand tapping operations. With an overall length of 2.719 inches and a thread length of 0.69 inches, it suits benchtop and machine-assisted tapping setups alike. The bottoming chamfer allows threading to be taken close to the bottom of a blind hole, which is critical in close-tolerance machining applications. It carries a 6H class of fit with a D5 thread limit, meeting standard Metric Fine tolerances for production and repair work.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for threading M8x1.00 Metric Fine holes in alloy steel, carbon steel, aluminum, and free-machining stainless steel. It is commonly used in machine shops, maintenance and repair operations, and general fabrication environments where Metric Fine thread standards are required. The bottoming chamfer makes it appropriate for second or third pass use following a taper or plug tap, or as the primary tap when full thread depth near the bottom of a blind hole is needed.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM8x1.00 Metric Fine thread form with D5 thread limit and 6H class of fit\u003c\/li\u003e\n  \u003cli\u003eBottoming chamfer for threading close to the base of blind holes\u003c\/li\u003e\n  \u003cli\u003e4-flute straight flute geometry for chip management during hand tapping\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for durability across multiple workpiece materials\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — no coating buildup to affect thread tolerance\u003c\/li\u003e\n  \u003cli\u003eShank diameter of 0.318 inches with a 0.375-inch square drive for standard tap wrenches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with alloy steel, aluminum, carbon steel, and free-machining stainless steel workpieces.

Secure the workpiece fully before tapping and apply appropriate cutting fluid for the material being threaded. When following a taper or plug tap in a blind hole, clear chips between passes before advancing the bottoming tap. Handle high speed steel taps carefully to avoid chipping the flutes on hard or interrupted surfaces.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M8 x 1.00\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Metric Fine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Pitch\u003c\/strong\u003e: 1.00 mm\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: 6H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: D5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Bottoming\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.719 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.69 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.318 inches (8.08 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.238 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Blind Hole Threading, Through-Hole Threading\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Alloy Steel, Aluminum, Carbon Steel, Free-Machining Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1003\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: CLEVELAND\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C54538\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51695704146226,"sku":"C54538","price":28.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/77252b8b51d637b160e9bce4db4df750.jpg?v=1788337587","url":"https:\/\/voomisupply.com\/products\/cleveland-c54538-m8x1-00-bottoming-hand-tap-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
