Built to Series 550ASP standards and conforming to NAS 907 Type B specification, it features a 135-degree split point that reduces walking and lowers thrust requirements on entry. The straw-finish cobalt construction provides heat resistance beyond standard HSS, making it well suited for sustained production drilling. At 7.00 mm diameter with a straight cylindrical shank and right-hand spiral flute, this bit is a heavy-duty tool for trades and machinists who need consistent, repeatable results in demanding material.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is rated for use in stainless steel and other hardened materials where standard high-speed steel bits fail prematurely. It fits standard drill chucks that accept straight shanks at 7.00 mm (0.2756 inches) shank diameter. Typical applications include fabrication shops, mechanical contractors, and field service operations requiring clean, precise holes in corrosion-resistant or heat-treated stock. The 2-flute regular spiral design promotes chip evacuation in deep-hole applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt construction with straw finish for elevated heat resistance during extended cutting cycles\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces drill walking and cutting thrust on hard workpieces\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web configuration improves chip clearance and reduces chisel edge load\u003c\/li\u003e\n  \u003cli\u003eConforms to NAS 907 Type B specification for dimensional and performance consistency\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with regular spiral flute for reliable chip evacuation in stainless and hardened materials\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through design  -  suitable for standard drill press, mill, or hand-drill application\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a heavy-duty OEM-style jobber drill for use in standard straight-shank drill chucks; primary workpiece compatibility includes stainless steel and hardened materials per Series 550ASP application guidelines.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists, fabricators, or mechanical trade professionals using a drill press, CNC machine, or hand drill with a compatible chuck. Secure the straight shank fully in the chuck before operation and verify concentricity before drilling into hardened stock. Cutting fluid or coolant is recommended when drilling stainless steel to extend bit life, even though this bit does not feature internal coolant-through channels. Inspect the split point for chipping or wear before each use, as cobalt bits subjected to excess side-load can develop micro-fractures at the cutting edge.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 7.00 mm (0.2756 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 109.00 mm (4.2913 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 69.00 mm (2.7165 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 7.00 mm (0.2756 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 40.00 mm (1.5748 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\u003ePoint Type\u003c\/strong\u003e: Split Point\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\u003eDrill Bit Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Straw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel, Hardened Materials\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0010 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 550ASP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: NAS 907 Type B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 4.29 x 0.28 x 0.28 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.049 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: CHICAGO-LATROBE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 47880\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51743915376946,"sku":"47880","price":96.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/88c60e882918ae7af67a6219dfbc0a36_4035bdb3-26ba-460b-859d-769d21c9b709.jpg?v=1788851205","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-47880-cobalt-jobber-drill-bit-7-00-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
