Built from high-speed steel (HSS) with a black oxide finish, this bit handles ferrous metals, cast iron, and general-purpose materials commonly encountered in mechanical, HVAC, and plumbing fabrication work. The 118-degree point angle is the standard geometry for most metal drilling tasks. At 7.75 inches overall length with a 4.75-inch flute, it provides the depth access that standard-length bits cannot reach in deep-hole or stepped-component applications. The web-thinned, tapered web construction reduces thrust requirements and improves chip evacuation.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for use in hand-held drills, drill presses, and machine spindles where a straight-cylindrical shank is compatible. Trade professionals in HVAC, plumbing, and general mechanical work use taper length bits when drilling through structural members, deep flanges, or multi-layer assemblies where a jobber bit falls short. The right-hand spiral flute and standard point geometry make it a reliable general-purpose choice across a range of ferrous and non-ferrous base materials.

Secure the workpiece firmly before drilling and ensure the chuck is fully tightened on the shank before operation. Center-punch the target location to prevent walking at startup. Wear appropriate eye protection and use cutting fluid on ferrous metals to extend bit life and manage heat buildup.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.5000 inches (1\/2 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 7.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 4.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral (Regular)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High-Speed Steel (HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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: 0.35 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\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: C.40W.1270\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51731600179506,"sku":"C.40W.1270","price":43.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7093eef68ac628c9001ed9a08a1389ab.jpg?v=1788733052","url":"https:\/\/voomisupply.com\/products\/hertel-c-40w-1270-taper-length-drill-bit-1-2-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
