Built from micrograin solid carbide and coated with Ti-NAMITE-X, this bit delivers extended tool life and resistance to heat and abrasion in demanding production environments. It features an 11\/64 inch (0.2244 decimal inch) diameter, a 135-degree split point, and a web-thinned tip that reduces entry thrust and improves chip evacuation. The straight-cylindrical shank and two-flute spiral design support consistent chip flow and stable tool holding in standard drill chucks and collet systems. Machinists, tool-and-die tradespeople, and maintenance mechanics are the primary users of this type of bit.\u003c\/p\u003e\u003cp\u003eThe SGS 66427 is suited for general-purpose and precision drilling in ferrous metals, non-ferrous alloys, plastics, and composite materials. The universal primary workpiece material rating and high-performance grade designation make it appropriate for CNC machining centers, drill presses, and hand-held production drilling applications where tight tolerances and repeatable hole quality are required. The 3xD flute-to-diameter ratio supports controlled chip removal at moderate cutting depths.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for high hardness and wear resistance\u003c\/li\u003e\n\u003cli\u003eTi-NAMITE-X coating reduces friction and extends tool life in abrasive and high-heat applications\u003c\/li\u003e\n\u003cli\u003e135-degree split point with web thinning for low-thrust entry and accurate self-starting\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports internal coolant delivery for deep-hole and high-speed applications\u003c\/li\u003e\n\u003cli\u003eFour margins provide enhanced hole straightness and surface finish\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks and collet toolholders\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 6537 specification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a screw machine length drill bit for use in CNC machining centers, drill presses, and production drilling setups that accept a 0.2300 decimal inch straight-cylindrical shank.

Ensure the machine spindle is fully stopped and locked out before changing tooling. Verify chuck or collet runout is within acceptable tolerance before use, as excessive runout accelerates carbide tool wear and can cause breakage. Do not use this bit in hammerdrill or impact mode.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 11\/64 inches (0.2244 decimal inch \/ 5.70 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5984 inches (66 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.1024 inches (28 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2300 inches (6 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.4173 inches (36 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.0465 inches (1.18 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.1024 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Margins\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\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: Solid Carbide (Micrograin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Ti-NAMITE-X\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\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Universal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.00016 to +0.00063 inches (+0.004 to +0.016 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 142P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: DIN 6537\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\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: 66427\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51732073382194,"sku":"66427","price":219.27,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/23d9476572f93f8f4f64e1950581cbee.jpg?v=1788738900","url":"https:\/\/voomisupply.com\/products\/sgs-66427-screw-machine-drill-bit-11-64-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
