Built from cobalt high-speed steel and finished with a GUHRING Ignator coating, this tap delivers extended tool life in demanding production and maintenance environments. It cuts a metric coarse M12x1.75 thread to a 6H class of fit with a D6 thread limit, producing accurate, consistent threads with minimal hand dressing. With 4 flutes and a plug chamfer, it pushes chips forward through the workpiece, making it well suited for through-hole applications. Licensed machinists, toolroom techs, and production operators are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis tap is rated for through-hole threading operations across a broad spectrum of materials, including aluminum, aluminum alloy, free-cutting steel, structural steel, heat-treatable steel, case-hardened steel, sulfured steel, tool steel, cast iron, and stainless steel. It fits standard CNC machining center toolholders, tapping heads, and hand-tapping setups that accept its 0.367-inch shank diameter. The Series 4887 designation identifies it within the GUHRING standard tap program and is useful when cross-referencing catalog entries or placing repeat orders.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSpiral point design pushes chips forward, optimized for through-hole threading\u003c\/li\u003e\n  \u003cli\u003eCobalt HSS construction resists heat and wear in tough ferrous materials including stainless and tool steel\u003c\/li\u003e\n  \u003cli\u003eIgnator coating reduces friction and improves chip evacuation for longer tool life\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer provides gradual thread engagement and easier starting\u003c\/li\u003e\n  \u003cli\u003e4-flute geometry for strong cutting action and consistent 6H thread accuracy\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, D6 thread limit, no coolant-through requirement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for through-hole threading of M12x1.75 metric coarse threads in aluminum, aluminum alloy, cast iron, free-cutting steel, heat-treatable steel, case-hardened steel, structural steel, sulfured steel, tool steel, and stainless steel.

Ensure the machine spindle or tapping attachment is fully stopped and the workpiece is secured before engaging the tap. Follow applicable shop safety procedures and manufacturer feed-rate recommendations for the workpiece material. Do not reverse a spiral point tap in a blind hole, as the forward chip-pushing geometry is specific to through-hole applications.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M12x1.75\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Metric Coarse\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: 6H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: D6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer\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\u003eApplication\u003c\/strong\u003e: Through-Hole Threading\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt HSS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Ignator\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.381 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.944 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.367 inches\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: 4887\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.16 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: 9048870120000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51754397434162,"sku":"9048870120000","price":55.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/782b5812b84d40710a028f3553fb70f0_85f229c0-a481-4a35-8183-904e54e0dec4.jpg?v=1788945037","url":"https:\/\/voomisupply.com\/products\/guhring-9048870120000-spiral-point-tap-m12x1-75","provider":"Voomi Supply","version":"1.0","type":"link"}
