Built from high-speed steel with an oxide finish, this bit measures 31\/64 inches (0.4844 inches decimal) in diameter and features a 135-degree split point that reduces walking and cutting resistance at the start of the hole. The shortened screw machine length body — 3-11\/16 inches overall — provides added rigidity compared to jobber-length bits, making it well suited for drill press and CNC turret work where overhang must be minimized. A web-thinned, parallel-web construction further reduces thrust requirements during cutting.\u003c\/p\u003e\u003cp\u003eThis bit is a standard choice in machine shops, fabrication facilities, and production environments where consistent hole quality and bit longevity are priorities. The straight-cylindrical shank fits standard drill chucks without modification. Its heavy-duty grade rating makes it appropriate for repetitive drilling cycles in ferrous and non-ferrous metals. Licensed machinists, toolroom technicians, and production floor operators are the typical end users. It is also used in plumbing, HVAC, and electrical rough-in work where drilling through structural steel or heavy-gauge sheet metal is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e31\/64 inch diameter (0.4844 inches decimal) for precise hole sizing\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces bit walking and lowers entry thrust\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, parallel-web design decreases cutting resistance\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction with oxide coating for heat and wear resistance\u003c\/li\u003e\n\u003cli\u003eScrew machine length body (3-11\/16 inches OAL) adds rigidity over jobber-length alternatives\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute with straight-cylindrical shank for universal chuck compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use screw machine drill bit for standard drill chucks accepting a straight-cylindrical shank in the 0.4500 to 0.5000 inch diameter range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or trade technician. Secure the straight-cylindrical shank fully in the drill chuck and verify runout before beginning a drilling cycle. Always power down or de-energize the machine tool before changing bits. Follow applicable OSHA and shop-floor safety standards for rotating tooling, including proper workpiece clamping and appropriate cutting fluid application for the material being drilled.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 31\/64 inches (0.4844 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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-11\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2-3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size Range\u003c\/strong\u003e: 0.4500 to 0.5000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.88 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: HERTEL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 2386076\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51727320252722,"sku":"2386076","price":18.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9ca7079af2918847d16fcbbfe9c7b0dd.jpg?v=1788676266","url":"https:\/\/voomisupply.com\/products\/hertel-2386076-screw-machine-drill-bit-31-64-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
