Built from M42 cobalt high-speed steel, it handles alloy steels and aluminum where standard HSS bits wear prematurely. The 135-degree split point self-centers on contact, reducing the need for a center punch and minimizing walking on flat surfaces. At 4.016 inches overall length with a 2.008-inch flute length, the shortened screw machine geometry gives extra rigidity in drill press and CNC turret applications. Right-hand cut with a straight-cylindrical shank, this bit fits standard chucks without an adapter. The web-thinned parallel web reduces thrust and improves chip evacuation on deep cuts.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for metalworking shops, maintenance facilities, and machine shops running repetitive hole operations. The screw machine length profile is a standard choice for turret lathes, gang drills, and CNC machining centers where stub-length rigidity matters. Primary workpiece materials include alloy steel and aluminum, making it a practical option for automotive, aerospace, and general fabrication work. The heavy-duty M42 cobalt grade handles interrupted cuts and harder alloys better than M2 HSS equivalents.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt tool steel construction for extended tool life in alloy and aluminum materials\u003c\/li\u003e\n  \u003cli\u003e135-degree split point self-centers and reduces thrust on entry\u003c\/li\u003e\n  \u003cli\u003eScrew machine length (stub) profile increases rigidity and reduces deflection\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned parallel web improves chip flow and lowers cutting force\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flutes with regular helix angle for general-purpose chip evacuation\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard drill chucks and collets without adapters\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B94.11M and DIN 1897 specifications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use drill bit for machines accepting a 0.4724-inch straight-cylindrical shank.

Ensure the drilling machine is de-energized and the chuck key is removed before changing bits. Run at speeds and feeds appropriate for cobalt HSS in the workpiece material being drilled. Coolant-through is not supported on this bit; external flood or mist cooling is recommended for extended production runs in alloy steel.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.4724 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 4.016 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.008 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 2.008 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.4724 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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt (M42)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0010 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Alloy Steel, Aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2133\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASME B94.11M, DIN 1897 (ANSI, DIN)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.35 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: CLEVELAND\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C14818\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51696737714482,"sku":"C14818","price":34.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1ef1767c48c22147ea688ce544fe7fc0.jpg?v=1788345699","url":"https:\/\/voomisupply.com\/products\/cleveland-c14818-screw-machine-drill-bit-0-4724-in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
