Manufactured from micrograin solid carbide and finished with a TX coating, it delivers extended tool life and heat resistance in demanding applications. The 135-degree split point reduces thrust and self-centers on contact, minimizing walking without a center punch. With a 3.6 mm diameter (0.1417 inches) and a right-hand spiral flute, this bit is designed for precision hole-making in production environments. Licensed machinists, tool-and-die shops, and industrial maintenance technicians are the primary users.\u003c\/p\u003e\u003cp\u003eThe 66612 is rated for universal material application, making it suitable for steel, stainless, aluminum, cast iron, and similar workpiece materials. The Series 142P taper length geometry provides additional reach compared to jobber-length bits, useful when drilling deeper features or working through thicker stock. The 8xD flute-length-to-diameter ratio supports chip evacuation across the full 34 mm maximum drilling depth. Coolant-through capability allows internal coolant delivery directly to the cutting zone, reducing thermal load and improving chip flushing in CNC and production setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eTX coating for extended tool life and reduced friction at the cutting edge\u003c\/li\u003e\n\u003cli\u003e135-degree web-thinned point for reduced thrust and accurate self-centering\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports internal coolant delivery in compatible spindles\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute with 8xD ratio promotes efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCylindrical shank compatible with standard drill chucks and collet holders\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 6537 specification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and production drill bit for use in CNC machining centers, drill presses, and manual machines equipped with standard cylindrical-shank toolholders or collets sized for a 5.99 mm shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified machinists or tooling technicians familiar with cutting tool setup. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the cylindrical shank fully and evenly in the collet or chuck to prevent runout. When using coolant-through capability, verify that the spindle and toolholder support internal coolant delivery before engaging the coolant circuit.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 3.6 mm (0.1417 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 71.99 mm (2.95 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 34 mm (1.3386 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 35.99 mm (1.4173 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5.99 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Cylindrical\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: 0.74 mm (0.0293 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard Web-Thinned\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\u003eFlute Length to Diameter Ratio\u003c\/strong\u003e: 8xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 34 mm (1.3386 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Micrograin Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Universal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.00016\/+0.00063 inches; +0.004\/+0.016 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: High Performance\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: 66612\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51746998780210,"sku":"66612","price":393.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/947f6ed78cf4a92e725732e5335ce663_839454be-151f-4d09-aa13-730b940bd3a5.jpg?v=1788875218","url":"https:\/\/voomisupply.com\/products\/sgs-66612-taper-length-drill-bit-3-6mm-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
