Built from high speed steel (HSS) with an oxide finish, this bit measures 0.159 inches (wire size #21) in diameter with a 118-degree standard point angle. The shortened screw machine length body provides increased rigidity compared to jobber-length bits, reducing deflection when drilling in tight or confined spaces. It features a straight-cylindrical shank for use in standard drill chucks and a regular spiral, two-flute configuration for efficient chip evacuation. Installed by machinists, maintenance technicians, and metalworking tradespeople.\u003c\/p\u003e\u003cp\u003eThis bit is suited for drilling mild steel, aluminum, brass, and similar materials in production screw machine work, CNC drilling, and bench drill press operations. The ANSI-specification design and 3xD flute-to-diameter ratio make it appropriate for through-hole and blind-hole work in sheet metal, structural stock, and machined components. The 0.159-inch diameter falls within the 0.1500 to 0.2000 inch size range classification. It is sold individually with a minimum order quantity of 12 units.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.159-inch diameter, wire size #21, for precise hole sizing in metal fabrication\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle for general-purpose drilling in a wide range of materials\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction provides durability in metal-cutting applications\u003c\/li\u003e\n\u003cli\u003eOxide finish improves surface hardness and reduces friction during cutting\u003c\/li\u003e\n\u003cli\u003eScrew machine length body (2.125 inches overall) increases rigidity and reduces deflection\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, regular spiral, two-flute design promotes consistent chip removal\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an ANSI-specification screw machine length drill bit compatible with standard drill chucks accepting straight-cylindrical shanks in the 0.1500 to 0.2000 inch diameter range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is installed by machinists and metalworking technicians using standard drill chucks on drill presses, CNC machines, or hand drills. Ensure the workpiece is securely clamped and the machine spindle is at an appropriate speed for the material and bit diameter before drilling. Do not exceed the rated cutting capacity of the drill press or handheld tool. Use cutting fluid when drilling ferrous metals to extend bit life and improve hole quality.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1590 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: #21\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\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\u003eSpecification Designation\u003c\/strong\u003e: ANSI\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\u003eMinimum Order Quantity\u003c\/strong\u003e: 12\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: 61699062\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51747201745202,"sku":"61699062","price":47.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/610fc8c33e189fde3e986557a53e01e6.jpg?v=1788877397","url":"https:\/\/voomisupply.com\/products\/hertel-61699062-screw-machine-drill-bit-0-159-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
