STI taps cut oversized threads sized to accept Heli-Coil style wire thread inserts, restoring stripped or damaged threads to full load-bearing strength. This tap features a plug chamfer with 3 to 5 leading threads, which eases starting and works well in through-holes or holes with adequate clearance below the thread depth. Manufactured from high-speed steel with a bright uncoated finish, it delivers consistent cutting performance in a range of workpiece materials. Overall length is 2.5 inches. It is used by machinists, maintenance technicians, and trade professionals performing thread repair in the field or at a bench.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for thread repair and insert installation in maintenance, repair, and overhaul work across mechanical, HVAC, plumbing, and general industrial applications. The M5 x 0.8 metric coarse thread form is one of the most common fastener sizes in equipment encountered in trade work. The plug chamfer style makes this tap appropriate for production and repair use where the hole has sufficient depth for the chamfer to clear. It is intended for hand tapping operations and should be used with a proper tap wrench and appropriate cutting fluid for the workpiece material.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSTI thread form sized for Heli-Coil style wire thread inserts in M5 x 0.8 metric coarse\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer provides 3 to 5 thread lead-in for easy starting in through-holes and deep blind holes\u003c\/li\u003e\n  \u003cli\u003e3-flute design balances chip clearance and cutting edge support for hand tapping\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction provides durability across a range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish allows direct visual inspection of the cutting edges before and after use\u003c\/li\u003e\n  \u003cli\u003e2.5-inch overall length fits standard tap wrenches used in field repair work\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with M5 x 0.8 metric coarse STI thread inserts in standard Heli-Coil style thread repair systems.

Before tapping, verify the correct STI drill size for M5 x 0.8 has been used to prepare the hole. Use a calibrated tap wrench and apply cutting fluid appropriate for the workpiece material to extend tap life and improve thread finish. Back the tap off periodically to break chips and prevent tap breakage, particularly in blind holes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M5 x 0.8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Metric Coarse\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: D1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\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\u003eWeight\u003c\/strong\u003e: 0.2 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\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: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: K007257AS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51728685138226,"sku":"K007257AS","price":22.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0009b3b934ddabed29a13daf41708f1e.jpg?v=1788694970","url":"https:\/\/voomisupply.com\/products\/hertel-k007257as-hand-sti-tap-m5x0-8-metric-coarse-plug-chamfer","provider":"Voomi Supply","version":"1.0","type":"link"}
