Ground from micrograin solid carbide, it holds tighter tolerances and outlasts high-speed steel in abrasive or hard materials. The bit is sized to wire gauge No. 57, equal to 0.0430 inches (1.09 mm) in diameter, with a 118-degree faceted point angle and a web-thinned, tapered web configuration that reduces entry force and improves chip evacuation. Overall length is 1.5 inches. This is a right-hand-cut, two-flute spiral design conforming to DIN 338 and intended for production or maintenance drilling where hole accuracy and bit longevity matter.\u003c\/p\u003e\u003cp\u003eThe SGS 51057 is suited to applications where small, precise holes are required in composite panels, plastics, or similar materials. The uncoated bright finish and micrograin carbide grade make it a practical choice for aerospace, electronics assembly, and general precision fabrication shops. It is sold and stocked as a single unit (package quantity of 1), making it accessible for both bench-level maintenance tasks and higher-volume production setups where individual replacement bits are pulled as needed.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for superior wear resistance compared to HSS in abrasive or composite materials\u003c\/li\u003e\n\u003cli\u003e118-degree faceted point with web-thinned, tapered web for reduced thrust and cleaner entry\u003c\/li\u003e\n\u003cli\u003eRegular spiral flute with 0.75-inch flute length and maximum drilling depth of 0.6093 inches\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank at 0.0430 inches diameter with shank length of 0.83 inches\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of -0.0005 to 0.0000 inches for consistent, close-tolerance hole sizing\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 338 standard; Series 101 with 5xD flute-to-diameter ratio\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit jobber-length drill bit for any standard drill chuck or collet accepting a straight cylindrical shank at 0.0430 inches diameter.

Carbide is brittle  -  avoid side loading, interrupted cuts, or use in hand-held drills where runout cannot be controlled; breakage risk increases significantly without a rigid setup. Secure the workpiece firmly before drilling and confirm spindle runout is within acceptable limits for the diameter being drilled. Consult the machine manufacturer and applicable shop safety procedures before use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: No. 57\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.0430 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (mm)\u003c\/strong\u003e: 1.09 mm\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\u003eOverall Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 0.83 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0430 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: 0.6093 inches\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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\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: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Composite\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\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\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\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: 51057\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51742213308722,"sku":"51057","price":37.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4b47a664bcae23e2048bd3cda1210449.jpg?v=1788835931","url":"https:\/\/voomisupply.com\/products\/sgs-51057-jobber-drill-bit-no-57-0-0430-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
