Built to DIN 6539 standards, it features a 140-degree standard point angle and a web-thinned geometry that reduces thrust and improves chip evacuation at entry. The cutting diameter is 0.1890 inches (No. 12 wire size, 4.80 mm), with a shank diameter of 0.1890 inches. Flute length is 1.125 inches and overall length is 2.1875 inches. The bright, uncoated finish on micrograin carbide substrate maintains sharp cutting edges in demanding applications. This bit is intended for use by machinists and tool-and-die professionals working with production drilling equipment.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is rated for primary use in cast iron, hardened steel, and steel workpieces, with secondary capability in hardened materials. Straight-flute geometry makes it well suited for drilling brittle materials where a conventional spiral flute would cause chipping or grab. It is appropriate for CNC machining centers, drill presses, and manual machines where controlled, low-vibration entry is required. The two-flute, right-hand cutting configuration is standard for these applications. Maximum drilling depth is 0.906 inches, making it appropriate for through-hole and moderate blind-hole work in production or toolroom environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for rigidity and edge retention in hard materials\u003c\/li\u003e\n  \u003cli\u003e140-degree standard point angle optimized for fast, accurate entry in steel and cast iron\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned design reduces axial thrust and improves chip clearance\u003c\/li\u003e\n  \u003cli\u003eStraight-flute geometry minimizes grab and cracking risk in brittle workpieces\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suitable for use with cutting fluids or dry\u003c\/li\u003e\n  \u003cli\u003eManufactured to DIN 6539 standard for dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard drill chucks and collets accepting a 0.1890-inch shank diameter. Primary workpiece materials are cast iron, hardened steel, and steel; rated for secondary use in hardened materials per supplier specification.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use of this drill bit should be performed by qualified machinists or toolroom personnel familiar with carbide tooling. Secure the shank fully in a precision drill chuck or collet before operation and verify runout is within acceptable limits, as carbide is brittle and sensitive to lateral loading. Do not use this bit in hammer-drill or percussion mode. Apply appropriate cutting fluid for the workpiece material unless running dry per shop practice, and do not exceed the maximum drilling depth of 0.906 inches per pass without retracting to clear chips.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Type\u003c\/strong\u003e: Straight-Flute\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.1890 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (mm)\u003c\/strong\u003e: 4.80 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide, Micrograin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Uncoated (Bright)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 2.1875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1890 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.130 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.906 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\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\u003eCoolant Through\u003c\/strong\u003e: No\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: 56012\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51732177813810,"sku":"56012","price":68.98,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dac7bd34a2e74fd0054dfe015736b28a.jpg?v=1788740104","url":"https:\/\/voomisupply.com\/products\/sgs-56012-straight-flute-drill-bit-no-12-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
