Manufactured from micrograin solid carbide and coated with Ti-NAMITE-X (TX), this bit delivers superior wear resistance and heat dissipation compared to standard HSS tooling. It measures 11\/32 inches in diameter with a 135-degree split point and a spiral flute design. Overall length is 5-19\/32 inches, with a flute length-to-diameter ratio of 8xD. The web-thinned point reduces thrust force at entry, making it well suited for precise, consistent hole starts. Coolant-through construction supports high-speed machining cycles. This bit is installed by machinists and tool-and-die professionals in production and maintenance environments.\u003c\/p\u003e\n\u003cp\u003eDesigned for universal material application, the SGS 66645 performs across a broad range of workpiece materials including steel, stainless steel, cast iron, and non-ferrous alloys. The straight cylindrical shank fits standard drill chucks and collet holders. Its DIN 6537 specification ensures dimensional compliance with metric and inch tooling systems. Typical use cases include precision hole-making in CNC machining centers, drill presses, and manual lathes where consistent diameter tolerance and hole quality are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide substrate with Ti-NAMITE-X coating for extended tool life\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces thrust and improves self-centering on entry\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned geometry lowers cutting forces and chip packing risk\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports high-speed and deep-hole drilling cycles\u003c\/li\u003e\n  \u003cli\u003e8xD flute-length-to-diameter ratio provides taper length reach\u003c\/li\u003e\n  \u003cli\u003eDIN 6537 specification ensures dimensional interchangeability with compliant tooling systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and general-purpose taper length drill bit compatible with standard straight cylindrical shank drill chucks and collet holders used in CNC machining centers and conventional drill presses.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists and tooling technicians. Ensure the machine spindle is fully stopped and locked out before changing tooling. Verify chuck or collet runout is within acceptable limits before seating the shank, as excessive runout will accelerate wear on carbide tooling. Follow the machine manufacturer and applicable shop safety guidelines when setting feed rates and spindle speeds for carbide drills.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 142P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 11\/32 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\u003eOverall Length\u003c\/strong\u003e: 5-19\/32 inches (114 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length to Diameter Ratio\u003c\/strong\u003e: 8xD\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\u003eFlute Type\u003c\/strong\u003e: Spiral (Regular)\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\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.00024 to +0.00083 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 1.43 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: DIN 6537\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Universal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: 66645\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51730603802930,"sku":"66645","price":464.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/61f3de9ae8f85d39826bb36110a8ca40.jpg?v=1788720192","url":"https:\/\/voomisupply.com\/products\/sgs-66645-taper-length-drill-bit-11-32-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
