Built from micrograin solid carbide and finished with a Ti-NAMITE-X (TX) coating, this bit delivers superior wear resistance and heat management at the cutting edge. It features a 135-degree split point for fast penetration and reduced walking on entry. The 31\/64-inch diameter, right-hand spiral flute design and cylindrical shank make it compatible with standard drill chucks and CNC toolholders. Coolant-through capability supports high-speed machining applications where chip evacuation and thermal control are critical.\u003c\/p\u003e\u003cp\u003eThe SGS 66634 is suited for production and job shop environments where extended tool life and tight hole tolerances are required. The 8xD flute-to-diameter ratio and taper length body give it reach for deeper holes without sacrificing rigidity. With a web-thinned point and DIN 6537 specification compliance, this bit is appropriate for aerospace, automotive, die-and-mold, and general metalworking applications. It is typically run by machinists and CNC operators on vertical machining centers, drill presses, and multi-axis platforms.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for extended tool life in demanding materials\u003c\/li\u003e\n\u003cli\u003eTi-NAMITE-X coating reduces friction and improves heat resistance at the cutting edge\u003c\/li\u003e\n\u003cli\u003e135-degree split point minimizes walking and reduces thrust force on entry\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports high-speed, deep-hole drilling with effective chip evacuation\u003c\/li\u003e\n\u003cli\u003eWeb-thinned geometry lowers cutting forces and improves chip flow\u003c\/li\u003e\n\u003cli\u003eDIN 6537 specification compliance ensures dimensional consistency for precision applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit taper length drill bit for use in standard straight-shank toolholders, drill chucks, and collet systems accepting a 31\/64-inch cylindrical shank.

Ensure the spindle and toolholder are clean and free of debris before seating the shank to maintain runout tolerance. Carbide tooling is brittle — avoid side-loading or using the bit as a reamer. Follow machine manufacturer guidelines for spindle speed, feed rate, and coolant pressure when running coolant-through applications.\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: 31\/64 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\u003eTool Material\u003c\/strong\u003e: Micrograin Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\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\u003eFlute Length\u003c\/strong\u003e: 5-15\/64 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 7 inches\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: 1-49\/64 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard, Web-Thinned\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: +0.00028 to +0.00098 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 1.20 mm\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: 0.06 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: 66634\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51747412082994,"sku":"66634","price":410.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8aa03dd2451fb1c87632c736732aa989.jpg?v=1788879749","url":"https:\/\/voomisupply.com\/products\/sgs-66634-taper-length-drill-bit-31-64-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
