It features a 118-degree standard point angle with web thinning for improved chisel-edge penetration and reduced thrust. The bright finish leaves the carbide substrate exposed for good heat visibility during use. At 2 inches overall length with a 1-inch flute length, this bit is suited for short-reach drilling in hard or abrasive materials where high-speed steel would wear prematurely. Machinists, tool-and-die techs, and precision fabricators are the primary users.\u003c\/p\u003e\u003cp\u003eThis bit is used in CNC machining centers, drill presses, and handheld precision drilling applications requiring tight-tolerance hole sizing in the 0.0500 to 0.1000 inch diameter range. Common applications include pilot holes, through-holes in hardened steel, stainless, cast iron, nonferrous alloys, and composite materials. The straight-cylindrical shank fits standard collets and keyless chucks without modification. The regular spiral flute geometry handles chip evacuation in both through-hole and blind-hole work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for superior wear resistance in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003e118-degree standard point with web thinning reduces entry thrust and improves self-centering\u003c\/li\u003e\n\u003cli\u003eBright finish coating maintains tight dimensional tolerance from -0.0005 to 0.0000 inches on diameter\u003c\/li\u003e\n\u003cli\u003eRegular spiral flute with tapered web configuration supports chip evacuation in both blind and through-hole drilling\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank at 0.0890 inches diameter fits standard collet systems\u003c\/li\u003e\n\u003cli\u003eC2 material grade carbide rated for high-performance cutting duty\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or upgrade for wire-size No. 43 jobber-length drill bits in applications requiring solid carbide performance within the 0.0500 to 0.1000 inch drill size range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eA licensed machinist or trained fabricator should install and operate this bit using appropriate machine speeds and feeds for solid carbide tooling. Secure the straight-cylindrical shank fully in the collet or chuck before operation to prevent runout. Do not use in handheld rotary tools not rated for carbide tooling. Inspect for chipping or cracking before each use, as solid carbide is brittle and can fracture if subjected to lateral loading or improper feed rates.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 43\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.0890 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\u003ePoint 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\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\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\u003eFlute Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 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: 0.0890 inches\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\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\u003eWeight\u003c\/strong\u003e: 0.012 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: 79891941\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51732027801906,"sku":"79891941","price":32.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/637eaa9c9cb766022d9ab62e272a53fa.jpg?v=1788738331","url":"https:\/\/voomisupply.com\/products\/hertel-79891941-solid-carbide-jobber-drill-bit-no-43","provider":"Voomi Supply","version":"1.0","type":"link"}
