Built to DIN 6537 specification, it features a 135-degree split point, a right-hand spiral flute, and a proprietary Ti-NAMITE-X (TX) coating for extended tool life and heat resistance. The 8.00 mm diameter and straight cylindrical shank make it compatible with standard drill chucks and tool holders. With micrograin carbide construction and a web-thinned point, this bit delivers clean entry, reduced thrust force, and consistent hole geometry in ferrous and non-ferrous materials. It is intended for use by machinists, tool-and-die professionals, and precision fabricators.\u003c\/p\u003e\n\u003cp\u003eThe SGS 66553 is suited for production drilling in CNC machining centers and manual drill presses where tight diameter tolerances and long tool life are required. The through-coolant design supports high-speed cutting in difficult materials by delivering coolant directly to the cutting edge. With a flute-to-diameter ratio of 5xD and a maximum drilling depth of 35.00 mm (1.378 inches), it handles moderate-depth holes in a single pass without pecking cycles in many applications. Series 142P positions it as a general-purpose yet high-performance solution for shops running precision hole work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for rigidity and wear resistance in high-cycle production work\u003c\/li\u003e\n  \u003cli\u003eTi-NAMITE-X (TX) proprietary coating reduces friction and extends tool life at elevated cutting speeds\u003c\/li\u003e\n  \u003cli\u003e135-degree web-thinned split point reduces entry thrust and improves self-centering without a pilot hole\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant capable design delivers cutting fluid directly to the drill tip for deep-hole temperature control\u003c\/li\u003e\n  \u003cli\u003eDIN 6537 specification ensures dimensional conformance for interchangeable tooling setups\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of +0.00016 to +0.00063 inches supports tight-tolerance hole requirements\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard production drill bit for CNC machining centers, drill presses, and multi-spindle setups requiring an 8.00 mm straight-shank jobber length carbide drill conforming to DIN 6537.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist familiar with carbide tooling handling requirements. Power down and lock out the machine spindle before loading or changing the drill bit. Carbide is brittle — avoid impact during handling and do not use this bit in a hammer or impact-style drilling mode. Verify chuck or collet runout is within acceptable limits before use, as excessive runout will accelerate chipping and premature failure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 8.00 mm (0.3150 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 91.00 mm (3.5827 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 53.00 mm (2.0866 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 35.00 mm (1.378 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 8.00 mm (0.230 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 36.00 mm (1.4173 inches)\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: 1.66 mm (0.0652 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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 Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Ti-NAMITE-X (TX)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.00016 to +0.00063 inches (+0.004 to +0.016 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: DIN 6537\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 142P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.11 pounds\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: 66553\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51731674628402,"sku":"66553","price":330.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/40bbeb29e008228609ffd6575f2b34e8_558243af-fa98-4072-8d71-334b6489ed4a.jpg?v=1788733780","url":"https:\/\/voomisupply.com\/products\/sgs-66553-solid-carbide-jobber-drill-bit-8mm-135-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
