Built from high-speed steel (HSS) with an oxide finish, it features a 135-degree split point that reduces walking on contact and cuts without a center punch in most applications. The Weldon flat shank with three flats resists slipping in chuck collets under torque. At 4 inches overall length with a 2.5-inch flute, this bit suits confined drilling scenarios typical in mechanical and fabrication work. It is intended for installation and service professionals working with drill presses or hand-held power tools.\u003c\/p\u003e\n\u003cp\u003eThis bit is rated for use on carbon steel, cast iron, high alloy steel, high tensile strength alloys, stainless steel, and general steel stock. The mechanics-length body — shorter than a jobber bit — improves rigidity and reduces deflection when drilling through structural members, brackets, or assemblies where hole precision matters. The right-hand spiral flute clears chips efficiently during through-hole and blind-hole operations. It is commonly used by HVAC technicians, pipefitters, electricians, and general mechanical trades for field and shop drilling tasks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point starts on contact and reduces drill walking without center punching\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction handles ferrous metals including stainless steel and cast iron\u003c\/li\u003e\n  \u003cli\u003eWeldon flat shank with three flats locks securely in compatible collet chucks\u003c\/li\u003e\n  \u003cli\u003eMechanics-length body (4 inches OAL) improves rigidity and reduces deflection versus jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eOxide coating provides corrosion resistance and light lubrication during cutting\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned parallel web reduces thrust force required during drilling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose mechanics-length drill bit compatible with Weldon flat collet chucks and drill presses accepting 5\/16-inch Weldon shank tooling.

Use appropriate cutting fluid or lubricant when drilling stainless steel or high alloy materials to extend bit life and reduce heat buildup. Inspect the cutting edges before each use — HSS bits used on hard alloys can show edge wear that is not always visible without close examination. Follow shop safety practices including eye protection and secure workpiece fixturing at all times.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 5\/16 inches (0.3125 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split Point\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\u003eShank Type\u003c\/strong\u003e: Weldon Flat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flats\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral (Regular)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Carbon Steel, Cast Iron, High Alloy Steel, High Tensile Strength Alloy, Stainless Steel, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 20916\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51691456561458,"sku":"20916","price":46.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5565c946cfaa11b273356e204e52d38b.jpg?v=1788285322","url":"https:\/\/voomisupply.com\/products\/value-collection-20916-mechanics-drill-bit-5-16-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
