Built from micrograin solid carbide, it delivers the hardness and edge retention required for drilling cast iron, hardened steel, carbon steel, and non-ferrous metals. The three-flute, right-hand spiral design improves chip evacuation and reduces chatter compared to standard two-flute bits. With a 3.75-inch overall length and a web-thinned, tapered web construction, this bit is suited for production drilling environments where hole quality and tool life are critical priorities. It is manufactured to DIN 6539 standards and carries a Series 103 designation.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is used in machine shop, fabrication, and maintenance environments where tight-tolerance holes are required in hard or abrasive workpiece materials. Typical applications include CNC drilling, manual mill work, and drill press operations on cast iron components, hardened steel fixtures, and non-ferrous stock. The AlTiN coating improves heat resistance at the cutting edge, making the bit well-suited for dry or minimal-lubrication drilling at higher spindle speeds. The straight cylindrical shank fits standard drill chucks and collet holders without modification.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for hardness and edge retention in abrasive materials\u003c\/li\u003e\n  \u003cli\u003eAlTiN (Ti-NAMITE-A) coating increases surface hardness and thermal resistance\u003c\/li\u003e\n  \u003cli\u003e150-degree split point reduces thrust and improves self-centering on entry\u003c\/li\u003e\n  \u003cli\u003eThree-flute regular spiral design enhances chip evacuation and hole finish\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web lowers cutting resistance and extends tool life\u003c\/li\u003e\n  \u003cli\u003eManufactured to DIN 6539 standards with a diameter tolerance of +0.0000 to -0.0005 inches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers, drill presses, and manual mills equipped with standard straight-shank drill chucks or collet systems accepting a 0.302-inch shank.

Secure the straight cylindrical shank firmly in a drill chuck or collet holder to the appropriate runout specification before operation. Ensure spindle speed and feed rate are set per the tooling manufacturer recommendations for the workpiece material and drill diameter. Inspect the cutting edges and coating condition before each use; carbide is brittle and may chip if subjected to impact or side-loading.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 0.302 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (mm)\u003c\/strong\u003e: 7.67 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 150 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.302 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.906 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\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\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN (Ti-NAMITE-A)\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\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Cast Iron, Hardened Steel, Non-Ferrous Metal, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 103\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 6539\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 4.25 inches L x 0.55 inches W x 0.55 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\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: 58073\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51753212870962,"sku":"58073","price":190.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f0896e2d3a14b02f7afdd69157abdd29_241dddf0-0bbf-4a4f-9416-2945ab0adebd.jpg?v=1788933950","url":"https:\/\/voomisupply.com\/products\/sgs-58073-solid-carbide-jobber-drill-bit-letter-n-0-302-in","provider":"Voomi Supply","version":"1.0","type":"link"}
