The 135-degree split point geometry reduces walking and thrust force at entry, making it well suited for hard or work-hardening materials. At 2.5 inches overall length, the screw machine format keeps the bit rigid and limits deflection in short-reach applications. The bright, uncoated finish means the carbide substrate is exposed as-ground, with no additional coating that could alter the cutting edge geometry. Two regular spiral flutes with a 1.25-inch flute length clear chips efficiently during the cut. This bit is sold individually and is intended for use by machinists, maintenance technicians, and tool-room personnel.\u003c\/p\u003e\u003cp\u003eThe TC20114 is suited for drilling operations where a standard jobber-length bit would flex or chatter due to its longer reach. Screw machine length bits are commonly used in CNC machining centers, turret lathes, drill presses, and hand-held operations where stub rigidity is a priority. The solid carbide construction makes it appropriate for cutting ferrous metals, cast iron, hardened steels, and other abrasive materials where high-speed steel tooling dulls prematurely. The straight cylindrical shank seats directly into standard drill chucks and collet holders without adapters.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLetter N size: 0.3020 inches decimal equivalent for precise hole sizing\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces entry thrust and eliminates the need for a center punch on most metals\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction withstands heat and abrasion in hard or abrasive workpieces\u003c\/li\u003e\n\u003cli\u003eScrew machine length (2.5 inches OAL) provides maximum rigidity and minimizes deflection\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish preserves as-ground cutting geometry with no coating buildup\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with regular spiral flutes for efficient chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct tooling selection for standard drill chucks and collet holders accepting a straight cylindrical shank in the Letter N diameter range (0.3000 to 0.3500 inches).\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified machinists or maintenance technicians familiar with rotating cutting tools. Ensure the spindle is fully stopped and the machine is de-energized or in a safe-lock state before loading or removing the bit from any chuck or collet holder. Inspect the shank and flutes for chips or cracks before each use, as solid carbide is brittle and can fracture if run with existing damage. Follow the machine manufacturer and tooling supplier feed and speed recommendations for the specific workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: N\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.3020 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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\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 Length\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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: 0.08 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: TITAN USA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: TC20114\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TITAN USA","offers":[{"title":"Default Title","offer_id":51731025985842,"sku":"TC20114","price":86.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/edf2575ef597bb8f9d8401683cfc1a0a_04875a3a-df4e-4c38-a975-9184616708a7.jpg?v=1788726028","url":"https:\/\/voomisupply.com\/products\/titan-usa-tc20114-drill-bit-letter-n-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
