Measuring 0.157 inches (No. 22 wire gauge) in diameter with a 118-degree standard point angle, it is shorter and more rigid than jobber-length bits, which reduces deflection and improves hole accuracy in production drilling environments. The 2-flute spiral flute design promotes efficient chip evacuation, while the oxide finish provides light corrosion resistance and reduces friction during cutting. Machinists, toolroom technicians, and maintenance mechanics use this bit in drill presses, CNC machines, and hand drills.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for light- to medium-duty drilling in screw machine shops, fabrication facilities, and maintenance applications where a compact, rigid drill is preferred. Its straight-cylindrical shank seats securely in standard drill chucks without requiring a collet or adapter. The general-purpose grade and ANSI specification designation make it a reliable shelf stock item for production and repair work across metal and non-ferrous material applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.157 inch diameter, No. 22 wire gauge sizing for precise hole matching\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle for general-purpose material entry\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for durability across a range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eOxide finish reduces friction and provides light corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length at 2-1\/8 inches overall for improved rigidity and reduced deflection\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, 2-flute spiral design for efficient chip removal\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose screw machine length drill bit conforming to ANSI standards, compatible with standard drill chucks accepting straight-cylindrical shanks in the 0.150 to 0.200 inch diameter range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis bit is installed and operated by machinists and mechanical tradespeople using drill presses, lathes, CNC equipment, or hand drills. Ensure the chuck is fully tightened and the shank is fully seated before operating. Use appropriate cutting fluid when drilling ferrous metals to extend tool life and improve hole finish. Inspect the cutting edges before each use and replace the bit if chipping or excessive wear is observed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.157 inches (No. 22 Wire Gauge)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-1\/16 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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003eSpecification Designation\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Range\u003c\/strong\u003e: 0.1500 to 0.2000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.13 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 61699799\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":67660871205170,"sku":"61699799","price":48.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/34cf29a2761c1a8d1bb80f6aa518e5b3.jpg?v=1790469151","url":"https:\/\/voomisupply.com\/products\/hertel-61699799-screw-machine-drill-bit-0-157-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
