Screw machine length bits are shorter than jobber-length equivalents, which increases rigidity and reduces deflection in high-cycle production and machining environments. The split point geometry starts on contact without a center punch, improving hole location accuracy. With two regular spiral flutes and a bright uncoated finish, this bit is suited for ferrous and non-ferrous materials where coating is not required. The straight cylindrical shank fits standard drill chucks. Overall length is 3 inches with a flute length of 1.375 inches.\u003c\/p\u003e\u003cp\u003eThis bit is used in CNC machining centers, drill presses, and hand-held drill motors in production shops, machine shops, and maintenance environments. Its stub-length design is preferred when drilling through fixtures, close to shoulders, or in tight axial clearance situations. The solid carbide body offers greater hardness and heat resistance than high-speed steel, making it appropriate for higher spindle speeds and harder workpiece materials. Installation and use are performed by machinists, tool and die makers, and maintenance mechanics.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLetter R size — 0.3390 inches diameter for precise hole sizing\u003c\/li\u003e\n\u003cli\u003e135-degree split point starts on contact, no center punch required\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for hardness and heat resistance at higher speeds\u003c\/li\u003e\n\u003cli\u003eScrew machine (stub) length at 3 inches OAL for increased rigidity and reduced deflection\u003c\/li\u003e\n\u003cli\u003eTwo regular spiral flutes with bright uncoated finish — no coating interference on close-tolerance applications\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits standard three-jaw drill chucks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or production-use bit for standard straight-shank drill chucks accepting 0.3390-inch diameter tooling in drill presses, CNC machining centers, and hand-held drill motors.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eDe-energize and lock out all machine power before installing or changing tooling. Secure the straight shank fully within the chuck jaws and verify concentricity before beginning a cut. Screw machine length bits require appropriate spindle speed and feed rate selection for the workpiece material — consult machining data references for solid carbide tooling. Inspect the cutting edges before each use; carbide is brittle and can chip if the bit is dropped or improperly stored.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: R\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.3390 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.375 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: Solid Carbide\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\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\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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: 200\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.11 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241635\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: TITAN USA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: TC20118\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TITAN USA","offers":[{"title":"Default Title","offer_id":51755869602098,"sku":"TC20118","price":101.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/edf2575ef597bb8f9d8401683cfc1a0a_bb114347-d3da-4df9-bc03-928afd31f4dd.jpg?v=1788960793","url":"https:\/\/voomisupply.com\/products\/titan-usa-tc20118-drill-bit-letter-r-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
