Built from solid carbide micrograin construction and finished with a TX coating, this bit delivers extended tool life and resistance to heat and wear. It features a 135-degree split point for self-centering entry and reduced thrust, minimizing walking on hard or slick surfaces. The 8xD flute-to-diameter ratio allows for deeper penetration relative to diameter. Web thinning further reduces cutting resistance at the tip. This bit is sized at 11\/64 inch (0.1614 inch decimal, 4.10 mm) and is installed by machinists, tool-and-die professionals, and skilled tradespeople using standard drill presses, CNC machines, or handheld drilling equipment.\u003c\/p\u003e\u003cp\u003eThe SGS 66617 is suited for universal material applications across metal, alloy, and similar workpiece materials. With a maximum drilling depth of 1.6929 inches (43.00 mm) and a cylindrical shank diameter of 5.99 mm, it fits standard collets and chucks without modification. The right-hand spiral flute evacuates chips efficiently during through-hole and blind-hole drilling operations. This bit conforms to DIN 6537 specification and is classified as a high-performance grade tool appropriate for production and maintenance machining environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide micrograin construction for hardness and thermal resistance\u003c\/li\u003e\n\u003cli\u003eTX coating reduces friction and extends cutting edge life\u003c\/li\u003e\n\u003cli\u003e135-degree standard point with web thinning for self-centering entry and lower thrust\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports high-speed and deep-hole drilling cycles\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 6537 specification for consistent dimensional accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eRated for universal material applications; fits standard cylindrical-shank collets and chucks accepting a 5.99 mm shank diameter on drill presses, machining centers, and CNC equipment.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified machinists or tradespeople familiar with cutting tool safety. Ensure the spindle and workpiece are secured before initiating rotation. When using the coolant-through feature, verify coolant supply lines are properly connected and pressurized per machine manufacturer specifications. Inspect the cutting edge for wear or chipping before each use and replace the bit if damage is detected to prevent workpiece damage or tool failure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Inch)\u003c\/strong\u003e: 11\/64 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1614 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (mm)\u003c\/strong\u003e: 4.10 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\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length (Inch)\u003c\/strong\u003e: 1-11\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length (Decimal Inch)\u003c\/strong\u003e: 1.6929 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length (mm)\u003c\/strong\u003e: 43.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (mm)\u003c\/strong\u003e: 81.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter (mm)\u003c\/strong\u003e: 5.99 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length (Inch)\u003c\/strong\u003e: 1-13\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length (Decimal Inch)\u003c\/strong\u003e: 1.4173 inches\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length x Diameter Ratio\u003c\/strong\u003e: 8xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.6929 inches (43.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Universal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +.00016\/+.00063 inches; +0.004\/+0.016 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.0334 inches (0.85 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: DIN 6537\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: High Performance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 142P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 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: 66617\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51735605346610,"sku":"66617","price":408.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/947f6ed78cf4a92e725732e5335ce663_490603ba-f687-4860-a7bb-8f847dc5e6e1.jpg?v=1788773216","url":"https:\/\/voomisupply.com\/products\/sgs-66617-taper-length-drill-bit-11-64-inch-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
