Built from micrograin solid carbide, this bit delivers the hardness and edge retention needed for precise small-hole drilling. The bright, uncoated finish and web-thinned tip reduce entry resistance and help maintain accuracy at tight tolerances. Overall length is 1.5 inches with a 0.75-inch flute length. The two-flute regular spiral design promotes clean chip evacuation. Machinists, tool-and-die technicians, and precision fabricators are the typical users of this bit.\u003c\/p\u003e\n\u003cp\u003eThis bit is engineered for drilling composite materials, where edge sharpness and dimensional consistency are critical. Its 5xD flute-to-diameter ratio and straight cylindrical shank make it a practical choice for CNC machining centers, drill presses, and hand-operated precision spindles in production and job-shop environments. The Series 101 designation places it within a standardized product family designed for small-diameter, close-tolerance drilling work. It is equally applicable in aerospace fabrication, electronics assembly, and instrument manufacturing where wire gauge drill sizes are standard practice.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide construction for superior hardness and wear resistance\u003c\/li\u003e\n  \u003cli\u003e118-degree faceted point with web thinning for reduced thrust and clean entry\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, regular spiral flute for efficient chip removal\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance held to -0.0005 to 0.0000 inches for precise hole sizing\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank compatible with standard collets and chucks\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 338 standard for jobber-length drill geometry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a jobber-length drill bit for use in applications requiring No. 58 wire gauge diameter holes in composite and similar workpiece materials.

Carbide is brittle  -  avoid side loading, interrupted cuts, or excessive feed rates that can cause chipping or breakage. Ensure the spindle and workpiece are secure before operation, and verify chuck or collet runout is within acceptable limits to protect the bit and maintain hole accuracy. Coolant-through is not supported on this bit; use external coolant or air blast where required by the application.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: No. 58\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.0420 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (mm)\u003c\/strong\u003e: 1.07 mm\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\u003eMaterial\u003c\/strong\u003e: Micrograin 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\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\u003eFlute Length\u003c\/strong\u003e: 0.75 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\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0420 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\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.6093 inches\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003eSeries\u003c\/strong\u003e: 101\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 338\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: SGS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 51058\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":52018742264114,"sku":"51058","price":37.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/949bf8d62a0bcf062d87732a03e5ba37.jpg?v=1790010414","url":"https:\/\/voomisupply.com\/products\/sgs-51058-solid-carbide-jobber-drill-bit-no-58-0-0420-in","provider":"Voomi Supply","version":"1.0","type":"link"}
