Built from micrograin solid carbide and left uncoated, it features a 140-degree standard point angle and a web-thinned tip geometry that reduces thrust and improves chip evacuation at entry. The cutting diameter is 0.4200 inches (27\/64 inch nominal), with a diameter tolerance of +0.0000 to -0.0005 inches. Right-hand cutting direction with 2 flutes. Licensed machinists, tool-and-die technicians, and industrial maintenance mechanics are the primary installers. It conforms to DIN 6539 standards and is sold individually.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for drilling cast iron, hardened steel, and general steel workpieces, as well as hardened materials classified as secondary workpiece materials. Its 3xD flute-to-diameter ratio and web-thinned point make it appropriate for short to medium depth holes in rigid setups such as milling machines, CNC machining centers, and drill presses where runout is controlled. The Series 106 designation places it in SGS's catalog line for precision carbide straight-flute tooling.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for hardness and wear resistance in ferrous materials\u003c\/li\u003e\n\u003cli\u003e140-degree standard point angle with web-thinned tip for reduced entry thrust\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of +0.0000 to -0.0005 inches for precision hole sizing\u003c\/li\u003e\n\u003cli\u003eUncoated bright finish suitable for use with cutting fluid on hardened materials\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 6539 dimensional standard\u003c\/li\u003e\n\u003cli\u003eNo coolant-through feature — external coolant or cutting oil required\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in rigid machine tool setups including CNC machining centers and drill presses where straight-flute carbide tooling in the 27\/64 inch diameter range is specified for cast iron, steel, and hardened steel workpieces.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eStraight-flute carbide drill bits must be run in rigid, vibration-free setups — avoid use in handheld drills, as carbide is brittle and will fracture under lateral loading. Verify spindle runout is within acceptable limits before use to protect the tight diameter tolerance. Apply appropriate cutting fluid or coolant externally, as this bit does not have through-coolant capability. Handle carbide tooling carefully during storage and changeover to prevent chipping of the cutting edges.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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 Diameter (Fractional)\u003c\/strong\u003e: 27\/64 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal)\u003c\/strong\u003e: 0.4200 inches\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\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\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.6090 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.3750 inches (3-3\/8 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.4219 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.5650 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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Micrograin Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Uncoated (Bright)\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\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: 56127\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51753191571762,"sku":"56127","price":192.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2adbbd521eca9be14108f6912701eac1_ef3201b5-4385-402a-8961-3d6b4c6191a9.jpg?v=1788933695","url":"https:\/\/voomisupply.com\/products\/sgs-56127-straight-flute-carbide-drill-bit-27-64-in","provider":"Voomi Supply","version":"1.0","type":"link"}
