Built to the E651 specification with a notched point geometry, this tool reduces the axial force needed to start the cut and helps clear chips more efficiently than a standard point. The thread specification is 8-32 UNC, a coarse-thread Unified National Coarse size common in light mechanical assemblies. Machinists, maintenance technicians, and pipe and electrical trade professionals use combination drill-taps to streamline fastener work in production and field service settings.\u003c\/p\u003e\u003cp\u003eThis combo drill-tap is suited for use in ferrous and non-ferrous materials where a tapped through-hole is required. The 8-32 UNC size is widely used in electrical panel work, equipment enclosures, junction boxes, and general sheet metal or light structural applications. The HSS construction provides adequate hardness and wear resistance for hand-tapping operations and low-speed machine tapping. The notched point promotes self-centering and reduces walking on entry, which is useful when drilling into finished surfaces without a center punch.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCombination drill-tap completes pilot drilling and thread cutting in one operation\u003c\/li\u003e\n\u003cli\u003e8-32 UNC thread form for standard coarse-thread fastener applications\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel (HSS) construction for durability across ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eNotched point geometry promotes self-centering and efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eE651 specification design for consistent dimensional accuracy\u003c\/li\u003e\n\u003cli\u003eSold individually — minimum order quantity of one\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 8-32 UNC combination drill-tap for use in hand-tap handles, drill presses, or low-speed tapping machines that accept standard shank tooling of this size class.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tool should be installed and operated by machinists or qualified tradespeople familiar with tapping speeds and feeds for HSS tooling. Always use appropriate cutting fluid for the material being tapped to extend tool life and improve thread quality. Secure the workpiece firmly before beginning the operation, and run at low RPM consistent with HSS tapping recommendations for the material. Avoid reversing under power without a reversing tap attachment to prevent tool breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 8-32 UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Style\u003c\/strong\u003e: Notched Point\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel (HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: E651\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Unified National Coarse (UNC)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSold As\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PRECISION TWIST DRILL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 0273272\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51345377362226,"sku":"0273272","price":26.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310538485.jpg?v=1782056350","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-0273272-combo-drill-tap-8-32-unc-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
