Built to DIN 6539 standards, it features a 25\/64 inch (0.3906 inch decimal) diameter with a 140-degree standard point and web-thinned tip geometry that reduces entry thrust and walking. The micrograin carbide construction delivers the edge retention needed when drilling cast iron, hardened steel, and other demanding workpiece materials. Right-hand cutting direction and a bright, uncoated finish make it straightforward to inspect for wear. This bit is a shop staple for machinists, tool and die technicians, and maintenance pros working with ferrous alloys.\u003c\/p\u003e\n\u003cp\u003eThe SGS 56125 is suited for production and maintenance drilling applications where tight tolerances and edge stability matter. Its 3xD flute-to-diameter ratio and 1-7\/8 inch flute length support clean chip evacuation in short-to-medium depth holes up to 1 inch deep. The straight-flute design makes it especially effective in brittle materials such as cast iron, where spiral flutes can induce chipping. It is a direct fit for CNC machining centers, drill presses, and manual mills using standard straight-shank toolholding.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for extended tool life in hardened and ferrous materials\u003c\/li\u003e\n  \u003cli\u003e140-degree standard point with web-thinned tip reduces entry thrust and improves self-centering\u003c\/li\u003e\n  \u003cli\u003eStraight-flute geometry optimized for brittle materials including cast iron and hardened steel\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish — no coating interaction with workpiece chemistry, easy wear inspection\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of +0.0000 to -0.0005 inches for consistent, close-tolerance hole sizing\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 6539 standard for straight-flute carbide drills\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in straight-shank drill chucks and collet holders on CNC machining centers, drill presses, and milling machines.

Ensure the shank is fully seated and the chuck or collet is torqued to the toolholder specification before starting the cut. Solid carbide is brittle — avoid side-loading, interrupted cuts without proper feeds and speeds, or dropping the bit on hard surfaces. Verify spindle runout is within acceptable limits before running tight-tolerance holes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 25\/64 inch (0.3906 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3906 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.56 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Micrograin Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Uncoated (Bright)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: 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: +0.0000 to -0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Hardened Steel, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Hardened Materials\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 106\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 6539\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: 56125\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51728692838706,"sku":"56125","price":134.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2adbbd521eca9be14108f6912701eac1_a40851c8-626d-4530-8a3c-52a302fbf96a.jpg?v=1788695130","url":"https:\/\/voomisupply.com\/products\/sgs-56125-straight-flute-drill-bit-25-64-inch-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
