Built from high speed steel with a bright, uncoated finish, it delivers reliable performance across a range of machinable metals and plastics. The taper chamfer — typically 8 to 10 threads — guides entry into the hole and distributes cutting load gradually, reducing the risk of tap breakage during startup. Overall length is 4.25 inches, and the four-flute configuration provides good chip clearance in standard drilling and tapping operations. This tap is intended for use in machine tapping and hand tapping by machinists, maintenance technicians, and trade professionals.\u003c\/p\u003e\u003cp\u003eThe K008594AS suits general-purpose tapping in ferrous and non-ferrous materials where a taper chamfer start is appropriate. Common applications include threading bolt-clearance repairs, fabrication work, and maintenance tapping on structural steel, cast iron, aluminum, and similar materials. The H3 thread limit provides a controlled oversize tolerance, making it suitable for producing threads that accept standard UNC fasteners with appropriate fit. This tap is sold and used as a single unit per package.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/4-10 UNC thread form for standard unified coarse thread applications\u003c\/li\u003e\n\u003cli\u003eTaper chamfer (approximately 8-10 threads) for gradual cutting load entry\u003c\/li\u003e\n\u003cli\u003eH3 thread limit for controlled oversize tolerance and proper fastener fit\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction for durability across a range of workpiece materials\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for use with cutting fluids\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction, compatible with standard tapping equipment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard straight flute taper tap for use in hand tapping and machine tapping setups that accept 3\/4-10 UNC tooling with a straight shank configuration.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eTapping operations should be performed by a qualified machinist or maintenance technician following standard shop safety practices. Ensure the workpiece is secured and the tap is properly aligned with the drilled hole before beginning. Use an appropriate cutting fluid to reduce friction and extend tool life. For machine tapping, verify spindle speed and feed rate are within the recommended range for the workpiece material and tap size.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/4-10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Taper\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: H3\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\u003eOverall Length\u003c\/strong\u003e: 4.25 inches\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: 1.82 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HERTEL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: K008594AS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51755102667058,"sku":"K008594AS","price":70.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/41709f3b60571ce104ff58524b84bfc0.jpg?v=1788951159","url":"https:\/\/voomisupply.com\/products\/hertel-k008594as-straight-flute-tap-3-4-10-unc-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
