It features a 118-degree standard point angle and a bright (uncoated) finish that suits a wide range of materials. The bit is web-thinned with a tapered web configuration, which reduces thrust and improves chip flow at the tip. Overall length is 2.5 inches, with a flute length of 1.375 inches. The straight-cylindrical shank measures 0.1610 inches in diameter. This is a high-performance grade C2 carbide bit intended for use by machinists, tool-and-die techs, and maintenance professionals who require tight diameter tolerances.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for precision hole-making in ferrous and non-ferrous metals, plastics, and composites in production and maintenance environments. The regular spiral with two flutes provides efficient chip evacuation in short-to-moderate depth holes. Jobber-length geometry keeps the bit rigid enough for accurate drilling without excessive deflection. It fits standard drill chucks and CNC toolholders that accept straight-cylindrical shanks at the 0.1610-inch shank diameter. No coolant-through capability is present, so external cutting fluid or dry operation is used based on material requirements.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction at material grade C2 for hardness and wear resistance\u003c\/li\u003e\n\u003cli\u003eWire gauge number 20 sizing at 0.1610 inches with a tolerance of -0.0005 to 0.0000 inches\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle with web-thinning for reduced entry thrust\u003c\/li\u003e\n\u003cli\u003eBright finish — no coating applied, suitable for a wide range of workpiece materials\u003c\/li\u003e\n\u003cli\u003eRegular spiral, two-flute design for efficient chip removal in jobber-length applications\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks and CNC collet holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement for jobber-length drill bits in wire gauge number 20 (0.1610 inches) with straight-cylindrical shanks.

Secure the shank fully in the chuck before operation and verify runout is within acceptable limits before beginning a cut. Apply appropriate cutting fluid for the workpiece material unless operating dry is specified. Carbide is brittle — avoid lateral loading or prying forces that can chip the cutting edges.\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\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.1610 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point 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\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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1610 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0005 to 0.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Bright\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: High Performance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 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: 79892238\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51734716940594,"sku":"79892238","price":49.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4748386d232d9870808a54f1a0688fdc.jpg?v=1788765816","url":"https:\/\/voomisupply.com\/products\/hertel-79892238-solid-carbide-jobber-drill-bit-wire-size-20","provider":"Voomi Supply","version":"1.0","type":"link"}
