Built from micrograin solid carbide with a bright uncoated finish, this bit delivers the hardness and edge retention needed for production drilling in cast iron, hardened steels, and abrasive composites. The 118-degree faceted point and web-thinned, tapered web geometry reduce entry force and improve chip evacuation. Machinists, tool-and-die workers, and maintenance professionals in fabrication and manufacturing environments rely on this class of tooling for consistent, repeatable hole quality.\u003c\/p\u003e\u003cp\u003eThe SGS 51212 suits applications where tight hole tolerances and tool longevity are priorities. Its jobber length profile  -  3.5 inches overall with a 2.125-inch flute length  -  fits standard drill chucks and CNC toolholders without extension. The 5xD flute-to-diameter ratio provides adequate chip clearance for moderate-depth holes. This bit is suited for use in drill presses, CNC machining centers, and handheld pneumatic or electric drills where a straight cylindrical shank is compatible. It conforms to DIN 338 standards for jobber length drill geometry.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for hardness and wear resistance in abrasive materials\u003c\/li\u003e\n\u003cli\u003e118-degree faceted drill point with web-thinned tapered web for reduced thrust and cleaner entry\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish  -  no coating buildup risk; suitable for re-grinding\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, 2-flute spiral design promotes efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits standard drill chucks and collets without adapters\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 338 jobber length standard for dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style jobber length drill bit conforming to DIN 338 standards, compatible with any drill chuck or straight-shank collet accepting a 0.290-inch diameter shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified machinists or maintenance technicians familiar with carbide tooling requirements. Secure the shank fully in the chuck or collet before operation, and confirm the drilling machine spindle speed is appropriate for carbide tooling in the target material. Carbide bits are brittle compared to high-speed steel  -  avoid side loads, interrupted cuts without proper setup, or dropping the tool on hard surfaces. Power down and lock out the machine before changing tooling per applicable safety procedures.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: L\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.290 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (mm)\u003c\/strong\u003e: 7.37 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: Micrograin Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Faceted\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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: 3.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.290 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.565 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.703 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0005 to 0.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 101\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 338\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: SGS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 51212\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51964065972530,"sku":"51212","price":110.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/19b97c14b6f7d5dc413a17c53d0f2c7c_118fc7e9-8bf1-4439-867b-c09940623668.jpg?v=1789948813","url":"https:\/\/voomisupply.com\/products\/sgs-51212-jobber-length-drill-bit-letter-l-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
