Manufactured from powdered metal and finished with a V coating, this bottoming tap produces threads to a 6H class of fit with a D3 thread limit. The 45-degree helix angle drives chips up and out of the flute, making it well suited for blind-hole tapping applications. At 56 millimeters overall length with a 19 millimeter tapping depth, it fits standard tool holders used on CNC machining centers and manual drill presses alike. A licensed machinist or tooling technician is the typical end user.\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for use on a broad set of workpiece materials including alloy steel, low-carbon steel, medium-carbon steel, high-carbon steel, cast iron, stainless steel, aluminum, and cast aluminum. Its bottoming chamfer allows threading to the base of a blind hole where plug or taper taps cannot reach. The right-hand flute direction and right-hand thread orientation are standard for conventional metric fastener applications in manufacturing, maintenance, and repair environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBottoming chamfer for full-depth threading in blind holes\u003c\/li\u003e\n  \u003cli\u003e45-degree helix angle evacuates chips efficiently during spiral flute tapping\u003c\/li\u003e\n  \u003cli\u003eV coating improves wear resistance and reduces built-up edge on difficult materials\u003c\/li\u003e\n  \u003cli\u003ePowdered metal construction provides consistent grain structure and toughness\u003c\/li\u003e\n  \u003cli\u003e6H class of fit with D3 thread limit meets standard metric tolerance requirements\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through design suits conventional coolant flood or dry tapping setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for tapping M3x0.50 metric coarse threads in alloy steel, aluminum, cast aluminum, cast iron, hardened steel, high-carbon steel, low-carbon steel, medium-carbon steel, and stainless steel workpieces.

Power down and secure the workpiece before tool changes. Ensure the tap holder provides adequate float or tension-compression compensation to prevent thread distortion. Follow shop-standard speeds and feeds for the workpiece material and tap diameter — do not exceed the tool or machine manufacturer's recommended parameters.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M3x0.50\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Metric (M)\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: D3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\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 Style\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 56 millimeters (approximately 2.205 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 4 millimeters\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 18 millimeters\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 19 millimeters\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3.5814 millimeters (0.141 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 2.794 millimeters\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 4.7625 millimeters\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Powdered Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: V Coated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.011 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 16500\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: OSG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1650009808\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51753615753522,"sku":"1650009808","price":69.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3960283163efc922807ec09ac636790c_4897d47e-038f-4c39-b126-491c47398484.jpg?v=1788938762","url":"https:\/\/voomisupply.com\/products\/osg-1650009808-spiral-flute-tap-m3x0-50-bottoming-6h","provider":"Voomi Supply","version":"1.0","type":"link"}
