It is manufactured from K40-grade solid carbide and features a nano-A coating that reduces friction and extends tool life when cutting hard, abrasive materials. The drill measures 7.2 mm in diameter with a 140-degree split point and a web-thinned tip for fast, accurate entry without a center punch. Overall length is 116 mm, with a 76 mm spiral flute. The straight cylindrical shank is 8 mm in diameter, making it compatible with standard collet chucks and drill chucks used in CNC and manual drilling operations. Coolant-through capability supports high-feed drilling in deep-hole applications.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is engineered for cutting stainless steel, nickel alloys, and titanium alloys  -  materials that are prone to work hardening and require a sharp, rigid cutting edge. The 7xD flute-length-to-diameter ratio and right-hand spiral flute geometry help evacuate chips efficiently during deep-hole drilling. It is suited for use in CNC machining centers, drill presses, and manual lathes in aerospace, medical device, and industrial manufacturing settings. Machinists and tooling specialists working with difficult-to-machine alloys rely on this class of carbide drill to maintain consistent hole tolerances.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eK40-grade solid carbide construction for rigidity and wear resistance in hard materials\u003c\/li\u003e\n  \u003cli\u003enano-A coating reduces built-up edge and thermal wear when drilling stainless steel and nickel alloys\u003c\/li\u003e\n  \u003cli\u003e140-degree split point with web thinning for precise entry and reduced thrust force\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports high-speed deep-hole drilling and chip evacuation\u003c\/li\u003e\n  \u003cli\u003e7xD flute length ratio provides extended reach for deeper holes without sacrificing rigidity\u003c\/li\u003e\n  \u003cli\u003eDrill bit diameter tolerance m7 ensures consistent, repeatable hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for machining stainless steel, nickel alloys, and titanium alloys.

Secure the shank fully in the collet or chuck and verify runout before operation. Always engage coolant supply before beginning the cut when using the through-coolant feature. Do not exceed the drill manufacturer recommended feed and speed parameters for the target workpiece material, as carbide tooling is brittle and susceptible to fracture under improper loading.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 5746\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 7.2 mm (0.2835 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: SU\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 76 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 116 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 8 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: 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: 7xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: m7\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: K40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: nano-A\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: Stainless Steel, Nickel Alloy, Titanium Alloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.048 pounds\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: GUHRING\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9057460072000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51743314280754,"sku":"9057460072000","price":388.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/97cc9c77a8e978e750225709c18b8783_bd883af4-fae3-46ab-b8b8-224a48bb2eb8.jpg?v=1788845516","url":"https:\/\/voomisupply.com\/products\/guhring-9057460072000-taper-length-drill-bit-7-2-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
