It features a bottoming chamfer, making it the right choice when threads must run close to the bottom of a blind hole. With 4 flutes and a bright uncoated finish, this tap is built for precision threading operations where tight tolerances and clean thread form are required. It carries an H5 thread limit, indicating a close-tolerance fit appropriate for precision assemblies. Licensed machinists and tooling technicians are the typical end users for this type of ground carbide tap.\u003c\/p\u003e\u003cp\u003eThis tap is suited for production and job-shop environments where metric coarse threading is performed on aluminum, cast aluminum, and cast iron workpieces. The straight flute design works best in these shorter-chipping materials, where chip evacuation is not a significant concern. It is appropriate for use in CNC machining centers and rigid tapping setups where controlled feed rates and spindle synchronization are available. The bottoming chamfer style makes it particularly well-suited for through-to-bottom blind hole applications requiring full thread depth.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBottoming chamfer for threading close to the bottom of blind holes\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in abrasive materials\u003c\/li\u003e\n\u003cli\u003eH5 thread limit for close-tolerance metric coarse thread production\u003c\/li\u003e\n\u003cli\u003e4-flute straight flute geometry optimized for short-chipping materials such as aluminum and cast iron\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish compatible with a wide range of cutting fluids\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction, M12x1.75 metric coarse standard\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for tapping M12x1.75 metric coarse threads in aluminum, cast aluminum, and cast iron.

Ensure the workpiece is securely fixtured and the hole is drilled to the correct tap drill diameter for M12x1.75 before tapping. Apply an appropriate cutting fluid for the workpiece material. Inspect the tap for wear or chipping regularly, as solid carbide tools can fracture if mishandled or run at incorrect feed-to-speed ratios.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003eChamfer Type\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\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating \/ Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 82 mm (approximately 3.23 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 38 mm (approximately 1.50 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 8.50 mm (approximately 0.335 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 9 mm (approximately 0.354 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 6.5 mm (approximately 0.256 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Aluminum, Cast Aluminum, Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 349\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.15 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112806\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 22837\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51755859640626,"sku":"22837","price":479.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1954b665d99b678b1d18be4da12d8a78.jpg?v=1788960613","url":"https:\/\/voomisupply.com\/products\/osg-22837-straight-flute-tap-m12x1-75-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
