Sized at 0.0160 inches in diameter, it features a 118-degree standard point angle and a regular spiral flute with right-hand cutting action. The tapered web configuration includes web thinning to reduce thrust and improve chip clearance when starting holes. At 0.875 inches overall length with a 0.1875-inch flute length, this bit is suited for precision small-hole drilling in metalworking and light fabrication tasks. Licensed trades and machine operators working in tight-tolerance applications will find this a dependable general-purpose tool.\u003c\/p\u003e\u003cp\u003eThis drill bit is rated for primary workpiece materials of steel and cast iron, making it appropriate for general-purpose metal drilling in production, maintenance, and repair environments. The straight cylindrical shank accepts standard keyless or keyed drill chucks across benchtop drill presses, hand drills, and CNC applications. No coolant-through capability is provided, so conventional flood or mist coolant applied externally is the standard approach for extended run applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNo. 78 wire size, 0.0160 inches diameter for precision small-hole work\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle with web thinning for reduced thrust on entry\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction with black oxide coating for corrosion and heat resistance\u003c\/li\u003e\n\u003cli\u003eRegular spiral flute with right-hand cutting direction\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n\u003cli\u003eGeneral-purpose grade rated for steel and cast iron workpieces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber drill bit for use in standard drill chucks accepting straight-shank bits in the 0.0160-inch diameter range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is installed and removed by a licensed machinist or qualified trade technician using a standard keyed or keyless chuck. Secure the workpiece firmly before drilling to prevent walking on entry. For extended runs in steel or cast iron, apply external cutting fluid to manage heat buildup and extend tool life. Inspect the cutting edges for wear before each use, as small-diameter HSS bits are susceptible to breakage when dull or subjected to side loading.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 78\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.0160 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.875 inches (7\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.1875 inches (3\/16 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0160 inches\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: 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\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered with Web Thinning\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\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 01188788\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51712769130802,"sku":"01188788","price":81.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/70c1ad02ee2557c6f6aecf5f3204156f.jpg?v=1788488485","url":"https:\/\/voomisupply.com\/products\/value-collection-01188788-no-78-hss-jobber-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
