Built from micrograin solid carbide and coated with Ti-NAMITE-X (TX) for extended wear resistance, this bit handles demanding applications where standard high-speed steel tooling falls short. The 135-degree split point reduces walking and thrust, while the web-thinned tip improves chip evacuation from the start of the cut. With an 8xD flute-to-diameter ratio and coolant-through capability, it is well suited for deep-hole drilling in production environments. The cylindrical straight shank mounts in standard drill chucks or collet holders without modification.\u003c\/p\u003e\u003cp\u003eThis drill bit is designed for use in CNC machining centers, drill presses, and manual machines where tight diameter tolerances and clean exit holes are required. The universal material application rating makes it appropriate for steel, stainless steel, cast iron, aluminum, and similar workpiece materials. Machinists, tool-and-die makers, and maintenance technicians working in metal fabrication, job shops, and industrial maintenance will find this bit applicable to a broad range of production and repair drilling tasks.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for high hardness and heat resistance\u003c\/li\u003e\n\u003cli\u003eTi-NAMITE-X coating provides enhanced lubricity and extended tool life\u003c\/li\u003e\n\u003cli\u003e135-degree standard point angle with web thinning reduces entry force and improves centering\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports internal coolant delivery for deep-hole applications\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute geometry promotes efficient chip removal\u003c\/li\u003e\n\u003cli\u003eMeets DIN 6537 specification for consistent dimensional accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard taper length drill bit compatible with CNC and manual drilling setups that accept a straight cylindrical shank at the specified 6.2 mm diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or maintenance technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully in the collet or chuck and verify runout before beginning a cut. When using the coolant-through feature, confirm that coolant pressure and flow rate are appropriate for the machine and workpiece material before engaging the spindle.\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: 6.2 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\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\u003c\/strong\u003e: Ti-NAMITE-X (TX)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular\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\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\u003eShank Length\u003c\/strong\u003e: 1-7\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 114 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 5-63\/64 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 1.29 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.00028 to +0.00098 inches (+0.007 to +0.025 mm)\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\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\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.09 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Dimensions (L x W x H)\u003c\/strong\u003e: 4.61 x 0.7 x 0.7 inches\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: 66638\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51735404970290,"sku":"66638","price":466.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7af1f1cdd3faddfcd6d9a61334aba80b.jpg?v=1788772300","url":"https:\/\/voomisupply.com\/products\/sgs-66638-taper-length-drill-bit-6-2mm-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
