Built from high speed steel with an oxide finish, this bit measures 0.161 inches in diameter (Wire Size 20) and features a 118-degree standard point angle suited for general-purpose drilling in steel, cast iron, aluminum, and similar materials. At 2.125 inches overall length, the screw machine format is shorter than jobber-length bits, improving rigidity and reducing deflection in drill press and CNC turret applications. The straight-cylindrical shank seats securely in standard drill chucks. This is a single-piece package unit with a minimum order quantity of 12.\u003c\/p\u003e\u003cp\u003eThis drill bit is intended for general-purpose shop drilling tasks including tap-hole preparation, clearance holes, and production runs in light to medium-duty metalworking. Its 1.0625-inch flute length and 3xD flute-to-diameter ratio make it well-suited for shallow-to-moderate depth holes where rigidity is a priority over deep-hole chip evacuation. Machinists, tool-and-die technicians, and maintenance professionals working in production shops or field repair settings will find this bit appropriate for frequent, repetitive drilling operations on metal workpieces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire Size 20 designation at 0.161 inches diameter for precise hole sizing in metal applications\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle provides self-centering entry on flat and curved metal surfaces\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction with oxide finish for improved wear resistance and heat management\u003c\/li\u003e\n\u003cli\u003eScrew machine length body at 2.125 inches overall reduces deflection compared to jobber-length alternatives\u003c\/li\u003e\n\u003cli\u003eTwo-flute regular spiral design promotes consistent chip evacuation during drilling\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank compatible with standard three-jaw drill chucks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose screw machine length drill bit for use with standard drill presses, CNC turret machines, and hand drills equipped with three-jaw chucks accepting straight-cylindrical shanks in the 0.150 to 0.200 inch diameter range per ANSI specification.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis drill bit should be installed by securing the straight-cylindrical shank fully into a properly sized drill chuck and tightening with a chuck key before operation. Ensure the drilling machine is powered off and brought to a full stop before changing bits. Use appropriate cutting fluid or coolant for the workpiece material to extend bit life, noting this bit does not support internal coolant-through delivery. Follow applicable ANSI and shop safety standards for rotating tool operation, including the use of eye protection and proper workpiece clamping.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 0.161 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.0625 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\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\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\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\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\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\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.13 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: HERTEL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 61699229\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51748150575410,"sku":"61699229","price":47.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d4aae1706a2ce36de8760f2f1c375586.jpg?v=1788889680","url":"https:\/\/voomisupply.com\/products\/hertel-61699229-screw-machine-drill-bit-0-161-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
