It features a bottoming chamfer, which allows threading close to the bottom of a blind hole where a plug or taper tap cannot reach. Built from high-speed steel (HSS) with a bright uncoated finish, this tap is suited for production and maintenance threading in aluminum, non-ferrous metals, and steel. The 52-degree helix angle promotes efficient chip evacuation up and out of the hole, reducing the risk of chip packing in tight applications. Licensed machinists, tool and die makers, and maintenance technicians are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for blind hole threading operations on a manual tap wrench, tapping head, or CNC machining center. The fast flute style and high helix angle make it particularly effective in aluminum and other non-ferrous materials where chip flow is a concern. It is also rated for use in steel. The 2B class of fit produces a standard tolerance internal thread suitable for most general mechanical assemblies requiring a metric fastener interface. Overall length is 3.375 inches, with a thread length of 1.66 inches and a shank diameter of 0.367 inches.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBottoming chamfer allows threading to within a few pitches of the bottom of a blind hole\u003c\/li\u003e\n  \u003cli\u003e52-degree helix angle evacuates chips efficiently in aluminum and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction provides toughness across a range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish maintains sharp edge geometry without added coating thickness\u003c\/li\u003e\n  \u003cli\u003eRight-hand flute and right-hand thread — compatible with standard tap drivers and CNC spindles\u003c\/li\u003e\n  \u003cli\u003eD6 thread limit provides consistent 2B class-of-fit tolerance output\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard tap wrenches, tapping heads, and CNC machining centers accepting a 0.367-inch round shank.

Use appropriate cutting fluid for the workpiece material — a sulfurized or aluminum-specific cutting oil is recommended depending on the substrate. Do not reverse a bottoming tap under power before confirming clearance depth; back the tap out manually if resistance increases unexpectedly. Follow shop safety protocols for rotating tooling and ensure the tap holder is properly aligned to avoid tap breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M12 x 1.75\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Metric\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Pitch\u003c\/strong\u003e: 1.75 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 2B\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\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Style\u003c\/strong\u003e: Fast\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 52 degrees\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\u003eApplication\u003c\/strong\u003e: Blind Hole Threading\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Aluminum, Non-Ferrous Metal, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1.66 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.367 inches (9.32 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.4375 inches (11.11 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.275 inches (6.99 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: 1094\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.7 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: CLEVELAND\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C58815\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51716584767794,"sku":"C58815","price":81.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/48e43454a26a5bb7b76a2bf605b9febd_505a56ef-e1f3-4078-ae40-b8307f08a0ca.jpg?v=1788528367","url":"https:\/\/voomisupply.com\/products\/cleveland-c58815-spiral-flute-tap-m12-x-1-75-metric","provider":"Voomi Supply","version":"1.0","type":"link"}
