It carries a bright, uncoated finish and measures 5.5 inches overall with a 4.0625-inch flute length. The straight cylindrical shank diameter matches the drill diameter at 0.4375 inches, making it compatible with standard drill chucks. A right-hand, regular spiral flute evacuates chips efficiently during through-hole and blind-hole operations. The web is thinned and tapered to reduce thrust and improve centering. This is a general-purpose bit suited for production and maintenance drilling tasks performed by machinists, pipefitters, HVAC technicians, and general trade professionals.\u003c\/p\u003e\u003cp\u003eThe -22377-B is rated as a general-purpose bit with aluminum and non-ferrous metals listed as the primary workpiece material. It is well-suited for drilling copper tubing brackets, aluminum enclosures, and similar non-ferrous components encountered in HVAC, plumbing, and electrical rough-in work. The 7\/16-inch diameter is a commonly specified size for bolt clearance holes and conduit knockout work. Coolant-through capability is not available on this model; flood or mist cooling applied externally is acceptable practice on harder non-ferrous stock.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e7\/16 inches (0.4375 inches) drill diameter with matching straight shank for secure chuck grip\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle with web-thinned, tapered web for reduced entry thrust\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction rated for general-purpose use in aluminum and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish — no coating buildup to affect hole tolerance over tool life\u003c\/li\u003e\n\u003cli\u003eRegular spiral flute, 4.0625 inches long, promotes consistent chip evacuation\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction, compatible with standard clockwise-rotation drill equipment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber drill bit for use with any standard drill press, hand drill, or CNC drilling equipment fitted with a chuck accepting a 0.4375-inch straight shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis drill bit is installed and operated by machinists, pipefitters, electricians, and other trade professionals using standard drill equipment. Always secure the workpiece before drilling and operate at a spindle speed appropriate for the workpiece material and bit diameter. Inspect the cutting edges before each use and remove from service if chipping or burning is observed. No coolant-through path is present; apply external cutting fluid when drilling harder non-ferrous alloys to extend tool life.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 7\/16 inches (0.4375 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 4.0625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.4375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel (HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Regular 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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum and Non-Ferrous\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: General Purpose\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: 0.01 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: IMPORT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: -22377-B\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IMPORT-GENERIC","offers":[{"title":"Default Title","offer_id":51695185002802,"sku":"-22377-B","price":49.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_92a505db-b013-478d-bfe3-85468a87ce5d.jpg?v=1788332238","url":"https:\/\/voomisupply.com\/products\/import-22377-b-jobber-drill-bit-7-16-inches-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
