Built from micrograin solid carbide and coated with Ti-NAMITE-X, this bit delivers extended tool life and resistance to heat buildup in demanding production environments. The 135-degree split point reduces thrust and improves hole entry accuracy without a center punch. At 3.11 inches overall length with a 1.61-inch flute length, the screw machine (stub) length format provides added rigidity over jobber-length bits, making it well suited for CNC machining centers, drill presses, and manual setups where chatter and deflection need to be minimized. The straight-cylindrical shank measures 0.31 inches in diameter. This bit is sold individually.\u003c\/p\u003e\n\u003cp\u003eThe SGS 66441 fits production and job-shop drilling applications where hole quality and tool life matter. The universal primary workpiece material designation means it performs across steel, stainless, cast iron, aluminum, and similar materials. Coolant-through capability supports high-speed drilling cycles in CNC applications where internal coolant delivery is available. The 3xD flute-to-diameter ratio and web-thinned geometry reduce cutting forces and help clear chips efficiently. Machinists, tool-and-die technicians, and CNC operators working in metalworking, fabrication, and maintenance environments are the primary users of this bit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide construction for superior hardness and wear resistance\u003c\/li\u003e\n  \u003cli\u003eTi-NAMITE-X coating provides thermal protection and extended cutting life\u003c\/li\u003e\n  \u003cli\u003e135-degree standard point with web thinning reduces entry thrust and eliminates need for center punching\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design compatible with CNC machining centers that provide internal coolant delivery\u003c\/li\u003e\n  \u003cli\u003eFour-margin geometry improves hole roundness and surface finish\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length format increases rigidity and reduces deflection compared to jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 6537 specification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a Series 142P screw machine length drill bit suitable for use in CNC machining centers, drill presses, and manual drilling setups that accept a 0.31-inch straight-cylindrical shank.

Ensure the machine spindle and chuck or collet are clean and properly sized for a 0.31-inch straight shank before securing the bit. Carbide tooling is brittle and should not be subjected to side loads, impact, or interrupted cuts beyond the tool design parameters. When coolant-through capability is used, verify coolant pressure is within machine specifications before initiating a drilling cycle.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 19\/64 inches (0.2795 inches \/ 7.10 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.11 inches (79 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.61 inches (41 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.31 inches (8.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.42 inches (36 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.61 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: 0.058 inches (1.47 mm)\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, 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\u003eTool Material\u003c\/strong\u003e: Solid Carbide, Micrograin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Ti-NAMITE-X\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\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: 3xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.00024 to +0.00083 inches (+0.006 to +0.021 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Universal\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\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 66441\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51749905203506,"sku":"66441","price":265.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/335eacf025b545d5af31bca16cffada3.jpg?v=1788911937","url":"https:\/\/voomisupply.com\/products\/sgs-66441-screw-machine-drill-bit-19-64-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
