The bit features a 118-degree standard point angle, a web-thinned tapered web for reduced thrust and cleaner entry, and a bright (uncoated) finish suited for applications where coolant or lubrication is applied externally. With a regular spiral, two-flute design and straight cylindrical shank, it fits standard chucks without adapters. Diameter tolerance is held to -0.0005 to 0.0000 inches, making it appropriate for close-tolerance hole work. This is a high-performance grade C2 carbide tool.\u003c\/p\u003e\u003cp\u003eThis drill bit is intended for use in CNC machining centers, drill presses, and hand-held precision drilling equipment where small-diameter, tight-tolerance holes are required. Common applications include circuit board work, instrument manufacturing, precision metalworking, and any operation calling for a No. 59 wire-gauge hole in ferrous or non-ferrous materials. The 1.5-inch overall length and 0.75-inch flute length make it most practical for shallow-hole drilling in thin stock or workpieces where deep penetration is not required. Coolant-through capability is not present, so external coolant or cutting fluid should be applied when drilling harder materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction (Material Grade C2) for hardness and wear resistance beyond HSS tooling\u003c\/li\u003e\n\u003cli\u003eNo. 59 wire size — 0.0410-inch diameter with tight tolerance of -0.0005 to 0.0000 inches\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle with web-thinned, tapered web for lower entry thrust\u003c\/li\u003e\n\u003cli\u003eTwo-flute regular spiral design for efficient chip evacuation in short-hole drilling\u003c\/li\u003e\n\u003cli\u003eBright finish — compatible with external coolant or cutting fluid application\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits standard drill chucks directly\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or standard tooling option for any application requiring a No. 59 wire-gauge jobber-length drill bit with a straight cylindrical shank and 118-degree point.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by a qualified machinist or tooling technician familiar with small-diameter carbide tooling. Secure the straight cylindrical shank firmly in a precision drill chuck rated for the spindle speed required by the workpiece material. Carbide is brittle — avoid side loading, interrupted cuts without proper feed rates, or dropping the bit, as chipping or fracture can result. Power down the machine completely and confirm zero spindle movement before changing or inspecting the bit.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 59\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.0410 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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral (Regular)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.75 inches (3\/4 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0410 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Bright\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\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\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: 79891735\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51730654036274,"sku":"79891735","price":25.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c568c8071757bd5383e5a3addedfaa7c.jpg?v=1788720924","url":"https:\/\/voomisupply.com\/products\/hertel-79891735-carbide-jobber-drill-bit-no-59","provider":"Voomi Supply","version":"1.0","type":"link"}
