It features a 140-degree split point geometry with web thinning on a tapered web for improved centering and reduced thrust. The bit is coated with AlTiCrSiN, a high-hardness physical vapor deposition coating that resists heat and wear at elevated cutting speeds. With a straight-cylindrical shank and two regular spiral flutes, this bit is designed for use in CNC machining centers, drill presses, and screw machine setups where consistent hole quality and tool life are critical. Coolant-through capability supports chip evacuation in deep-hole operations.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for production drilling in steel, stainless steel, cast iron, and other hard materials. The screw machine length format provides a shorter, more rigid cutting profile compared to jobber-length bits, making it well matched to high-feed, high-precision drilling cycles on modern CNC equipment. The SCD series designation indicates a flute-to-diameter ratio of 3xD, appropriate for moderate-depth holes in tough ferrous and hard materials where rigidity and heat management are priorities. Machinists and tooling technicians in precision manufacturing and metalworking shops are the primary users.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard materials\u003c\/li\u003e\n\u003cli\u003eAlTiCrSiN coating provides high heat resistance and extended tool life at elevated cutting speeds\u003c\/li\u003e\n\u003cli\u003e140-degree point angle with web thinning reduces entry thrust and improves self-centering\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports chip evacuation and thermal control in deep-hole drilling\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank for standard collet and chuck compatibility\u003c\/li\u003e\n\u003cli\u003eScrew machine length (3xD flute ratio) delivers a rigid, short cutting profile for precision CNC work\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style production drill bit in the ISCAR SCD series for CNC machining centers and screw machine setups drilling steel, stainless steel, cast iron, and hard materials.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Verify shank diameter tolerance and runout at the holder before securing; excessive runout will reduce tool life and hole accuracy. Coolant-through setups require a compatible toolholder and confirmed coolant pressure before running at rated feed and speed parameters.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: SCD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiCrSiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute to Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 45.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.90 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Hard Material\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.14 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241635\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ISCAR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3411505\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51727787852082,"sku":"3411505","price":127.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/354cd4284f6f482ed293cd0bb96c970a.jpg?v=1788682380","url":"https:\/\/voomisupply.com\/products\/iscar-3411505-carbide-screw-machine-drill-bit-140-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
