Built from micrograin solid carbide and coated with Ti-NAMITE-X, this bit delivers extended tool life and maintains dimensional accuracy through demanding production cycles. The 135-degree split point with web thinning reduces entry force and minimizes walking on workpiece surfaces. At 2.5984 inches overall length and a 15\/64 inch (0.1535 inch) diameter, it is sized for compact drilling setups where standard length bits are too long. Licensed tradespeople and machining professionals in industrial maintenance and fabrication environments are the typical users.\u003c\/p\u003e\u003cp\u003eThis bit is suited for applications requiring tight hole tolerances in universal workpiece materials including steel, stainless, aluminum, cast iron, and plastics. The screw machine length profile makes it a practical choice for CNC machining centers, turret lathes, and drill presses where rigidity and reduced overhang matter. Coolant-through capability supports high-speed, high-feed drilling operations where heat management is critical to tool life and hole quality. The four-margin design improves hole straightness and surface finish compared to standard two-margin configurations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for hardness and wear resistance\u003c\/li\u003e\n\u003cli\u003eTi-NAMITE-X coating for thermal protection and extended tool life\u003c\/li\u003e\n\u003cli\u003e135-degree standard point with web thinning reduces thrust and self-centers on entry\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports high-speed drilling operations\u003c\/li\u003e\n\u003cli\u003eFour-margin geometry improves hole roundness and surface finish\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard drill chucks and collets\u003c\/li\u003e\n\u003cli\u003eDIN 6537 specification compliance for dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a high-performance OEM-style screw machine drill bit for use in CNC machining centers, turret lathes, and drill presses accepting a 0.2300 inch straight-cylindrical shank.

Secure the straight-cylindrical shank in a properly sized collet or drill chuck to the chuck manufacturer's recommended clamping procedure. Verify coolant-through lines are clear and delivering adequate flow before beginning high-speed operations. Do not use this bit at feeds or speeds outside the tool manufacturer's published parameters for the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 15\/64 inches (0.1535 inch \/ 3.90 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5984 inches (66 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.9449 inches (24 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2300 inches (6 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.4173 inches (36 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.9449 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: 0.0318 inches (0.81 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\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\u003eFlute by 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\u003ePoint Type\u003c\/strong\u003e: Standard\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, Micrograin Grade\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Ti-NAMITE-X\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Universal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.00016 to +0.00063 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 142P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: DIN 6537\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: 66409\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51751899431218,"sku":"66409","price":208.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/69fd0261ca8fd3b2ac9ee6f10e4d2c3d.jpg?v=1788924621","url":"https:\/\/voomisupply.com\/products\/sgs-66409-screw-machine-drill-bit-15-64-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
