Built from micrograin solid carbide and coated with Ti-NAMITE-X (TX), it delivers extended tool life and thermal resistance in demanding applications. The 135-degree split point reduces thrust and improves self-centering on entry without a center punch. With a flute-to-diameter ratio of 8xD, a 95 mm flute length, and a 4-31\/64 inch overall length, this bit is suited for deeper holes than standard-length drills. A web-thinned geometry reduces cutting forces and chip packing. Installed by machinists and tool room professionals in CNC and manual drilling operations.\u003c\/p\u003e\n\u003cp\u003eThe SGS 66667 Series 142P is designed for universal material application, including steel, stainless, cast iron, aluminum, and non-ferrous alloys. It fits standard cylindrical straight-shank tool holders and collet chucks common in machining centers and drill presses. The coolant-through design channels cutting fluid directly to the tip, making it effective in deep-hole applications where chip evacuation and heat management are critical. It conforms to DIN 6537 specification, which is the recognized standard for carbide drill geometry in industrial metalworking environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eTi-NAMITE-X coating for elevated heat and abrasion resistance\u003c\/li\u003e\n  \u003cli\u003e135-degree web-thinned point for reduced entry thrust and self-centering\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports deep-hole chip evacuation\u003c\/li\u003e\n  \u003cli\u003e8xD flute-to-diameter ratio enables deeper reaches than jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 6537 specification for consistent geometry\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, spiral flute, straight cylindrical shank\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and production drill bit compatible with standard straight cylindrical shank tool holders, collets, and drill chucks rated for the 9.1 mm shank diameter.

Ensure the spindle and tool holder are fully powered down and locked out before mounting or removing the bit. Carbide tooling is brittle — avoid side-loading or interrupted cuts that could cause chipping or fracture. Verify coolant lines are clear and flow is confirmed before beginning deep-hole drilling cycles.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 9.1 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\u003ePoint Type\u003c\/strong\u003e: Standard, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 95 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4-31\/64 inches (141.99 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1-13\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 1.88 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 8xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular\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 (TX)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.00024 to +0.00083 inches (+0.006 to +0.021 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\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\u003ePackage Dimensions\u003c\/strong\u003e: 5.71 inches (L) x 0.7 inches (W) x 0.7 inches (H)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: 66667\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51733046133042,"sku":"66667","price":615.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ebeb886afb280caea11b6b30358ae2b0.jpg?v=1788750923","url":"https:\/\/voomisupply.com\/products\/sgs-66667-taper-length-drill-bit-9-1-mm-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
