Built from vanadium high speed steel (3% vanadium HSS), it delivers extended tool life in demanding applications including titanium and other difficult-to-machine materials. The modified bottoming chamfer allows threading close to the bottom of blind holes where standard plug or taper taps cannot reach. With 4 right-hand flutes at a 15-degree helix angle, this tap moves chips up and out of the cut efficiently, reducing the risk of re-cutting and tap breakage. Overall length is 4.25 inches and the finish is bright\/uncoated.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for production and maintenance machining environments where 3\/4-10 UNC internal threads are required. The H3 thread limit makes it appropriate for use with standard H3 tolerance thread gauges and fits within typical Class 2B and Class 3B thread requirements. Its design is particularly well matched to blind-hole applications in ferrous and non-ferrous metals, including titanium alloys, where a modified bottoming chamfer is specified. Machinists, toolroom technicians, and CNC operators in manufacturing and job-shop settings are the primary users.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/4-10 UNC thread size with right-hand thread direction\u003c\/li\u003e\n  \u003cli\u003eModified bottoming chamfer for threading close to the bottom of blind holes\u003c\/li\u003e\n  \u003cli\u003e4 right-hand spiral flutes at 15-degree helix angle for upward chip evacuation\u003c\/li\u003e\n  \u003cli\u003eVanadium high speed steel (3% vanadium HSS) construction for heat and wear resistance\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit for consistent tolerance control\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish; no coolant-through feature\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-use spiral flute tap for 3\/4-10 UNC blind-hole threading applications, including use in titanium as specified by the manufacturer material application rating.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tap is installed by a machinist or toolroom technician using a tapping machine, drill press with tapping attachment, or CNC machining center with rigid or floating tap holder. Ensure the workpiece is securely fixtured and that the correct tap drill diameter for 3\/4-10 UNC is used prior to tapping. Apply an appropriate cutting fluid for the workpiece material, particularly when tapping titanium, to reduce heat and galling. Inspect the tap for wear or chipping before each use and do not force a worn tap, as breakage in titanium is difficult to recover from.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/4-10 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Style\u003c\/strong\u003e: Spiral (Slow Helix)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 15 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Modified Bottoming\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\u003eThread Limit\u003c\/strong\u003e: H3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Vanadium High Speed Steel (3% Vanadium HSS)\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\u003eThread Length\u003c\/strong\u003e: 25.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 14.99 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Titanium\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: 0.25 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: T2657703\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51747780755762,"sku":"T2657703","price":210.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/153486cb8d1982978fc364ff68035eb4.jpg?v=1788885400","url":"https:\/\/voomisupply.com\/products\/accupro-t2657703-spiral-flute-tap-3-4-10-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
