The spiral flute geometry evacuates chips upward and away from the cutting zone, reducing the risk of chip packing in tight bores. Built from 3% vanadium high speed steel (HSS), it holds a sharp edge longer than standard M2 HSS in abrasive or work-hardening materials. The modified bottoming chamfer allows threading close to the bottom of a blind hole while still maintaining controlled entry. With an H5 thread limit and a 33-degree helix angle, this tap suits machinists and tool-and-die tradespeople working in ferrous metals, aluminum, and engineering plastics.\u003c\/p\u003e\u003cp\u003eThis tap is suited for manual tapping operations as well as low-speed CNC and turret-lathe applications where a spiral flute geometry is called for. The 6-40 thread size is common in instrument work, small fastener assemblies, electrical panel hardware, and precision mechanical components. The right-hand flute and right-hand thread configuration cover the vast majority of standard threaded hole requirements. Coolant-through capability is not included; flood or mist coolant applied externally at the tap is the appropriate cooling method.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e6-40 UNF thread form for fine-pitch small-diameter fastener applications\u003c\/li\u003e\n\u003cli\u003e3% vanadium high speed steel construction for extended edge retention\u003c\/li\u003e\n\u003cli\u003e33-degree helix angle promotes upward chip evacuation in blind holes\u003c\/li\u003e\n\u003cli\u003eModified bottoming chamfer enables threading near the base of a blind hole\u003c\/li\u003e\n\u003cli\u003eH5 thread limit provides consistent tolerance control for close-fit assemblies\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish compatible with standard cutting oils and tapping fluids\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard tooling selection for any machine or hand-tapping setup requiring a 6-40 right-hand spiral flute tap with an H5 thread limit.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap is installed and operated by machinists or tool-and-die technicians using a tap wrench, tapping head, or CNC spindle set to low RPM. Secure the workpiece fully before beginning the tapping cycle to prevent movement that can break the tap. Apply a suitable cutting oil or tapping fluid to lubricate the cutting edges and aid chip evacuation. Inspect the tap for wear or chipping before each use; a damaged tap in a blind hole can result in a broken tap extraction job that is costly and time-consuming.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 6-40\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Style\u003c\/strong\u003e: Modified Bottoming\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\u003eThread Limit\u003c\/strong\u003e: H5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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\u003eHelix Angle\u003c\/strong\u003e: 33 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 8.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3.58 mm\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: 0.1 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: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: T2634265\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51731213648178,"sku":"T2634265","price":30.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/69073aa7cdd53e8c5f0ee1079d6392ec_40684284-11c4-483e-912d-644090e7a5e1.jpg?v=1788728375","url":"https:\/\/voomisupply.com\/products\/accupro-t2634265-spiral-flute-tap-6-40-3-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
