It features a 118-degree faceted point angle with web thinning for faster, cleaner entry into work material. The bright, uncoated finish suits applications where coating is not required. With an overall length of 2.5 inches and a 1.375-inch spiral flute, the 51028 is built for precision drilling in metal, composites, and other materials common in trade and production environments. Micrograin carbide construction provides hardness and wear resistance suited to high-cycle or demanding drilling tasks. This is a right-hand cut, two-flute bit with a straight cylindrical shank.\u003c\/p\u003e\u003cp\u003eThe SGS 51028 is appropriate for use in hand-held drill presses, CNC machining centers, and bench-top drilling setups where wire-gauge hole sizing is required. Its 5xD flute-to-diameter ratio and tapered web configuration make it suitable for general-purpose through-hole and blind-hole work in ferrous and non-ferrous metals, plastics, and composites. It conforms to DIN 338 standards, making it compatible with standard collets and chucks accepting a 0.1405-inch straight shank. This bit is sold and packaged individually.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for extended wear life in demanding drilling applications\u003c\/li\u003e\n\u003cli\u003e118-degree faceted point with web thinning reduces entry force and improves hole accuracy\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, two-flute spiral design for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank at 0.1405 inches diameter fits standard collets and chucks\u003c\/li\u003e\n\u003cli\u003eDIN 338 compliant dimensions ensure interchangeability with standard tooling\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish compatible with a wide range of work materials and cutting fluids\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard tooling option for any setup requiring a No. 28 wire gauge jobber length drill bit with a straight cylindrical shank conforming to DIN 338 specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis drill bit is installed and serviced by machinists, toolmakers, and trade professionals operating drilling equipment. Ensure the drill chuck or collet is fully tightened and rated for the shank diameter before operation. Inspect the cutting edges for chips or wear before each use, as carbide is brittle and may fracture if the bit is dropped or improperly stored. Follow machine manufacturer guidelines for spindle speed and feed rate appropriate to the work material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 28\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.1405 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (mm)\u003c\/strong\u003e: 3.57 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint 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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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: Spiral (Regular)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.375 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\u003eShank Diameter\u003c\/strong\u003e: 0.1405 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.1093 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\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0005 to 0.0000 inches\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\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 51028\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51740938010930,"sku":"51028","price":53.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/aef545afd609cc6e0b34530edabd80cd.jpg?v=1788828479","url":"https:\/\/voomisupply.com\/products\/sgs-51028-jobber-drill-bit-no-28-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
