Built from solid carbide grade C2, it delivers the hardness and heat resistance required for drilling hard alloys, composites, and other difficult materials. The bit is wire gauge size 49, measuring 0.0730 inches in diameter, with a standard 118-degree point angle and a web-thinned, tapered web configuration that reduces thrust at entry and promotes clean hole starts. The bright finish leaves the carbide surface uncoated for direct contact performance. Installed by machinists and trade professionals working in metal fabrication, aerospace component work, and precision tooling environments.\u003c\/p\u003e\u003cp\u003eThis bit is suited for applications requiring tight-tolerance holes in the 0.0500 to 0.1000 inch diameter range. The 7\/8-inch flute length accommodates typical jobber-depth passes, and the straight-cylindrical shank fits standard drill chucks across benchtop drill presses, CNC machines, and hand-held electric drills. Right-hand spiral flutes evacuate chips efficiently without coolant-through capability, making it well matched to dry or externally lubricated setups in light production and maintenance drilling.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide C2 grade construction for high-performance drilling in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003eWire size 49 (0.0730 inches) 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 reduced entry thrust\u003c\/li\u003e\n\u003cli\u003eBright finish with 2 regular spiral flutes for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks\u003c\/li\u003e\n\u003cli\u003eOverall length of 1.75 inches with a 7\/8-inch flute length for jobber-depth drilling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use jobber drill bit for applications requiring wire gauge size 49 solid carbide tooling with a straight-cylindrical shank in the 0.0500 to 0.1000 inch diameter range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified machinists or trade professionals familiar with rotary cutting tools. Ensure the drill press, CNC spindle, or handheld drill is fully powered down and secured before loading or removing the bit from the chuck. Inspect the carbide tip for chipping or wear before each use, as solid carbide is brittle and susceptible to breakage if subjected to side loading or impact. Follow applicable shop safety codes and machine manufacturer guidelines for speed and feed rates appropriate to the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 49\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.0730 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\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\u003ePoint Type\u003c\/strong\u003e: Standard\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: 0.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.75 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: 0.0730 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\u003eDrill Bit Size Range\u003c\/strong\u003e: 0.0500 to 0.1000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\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: 79891859\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51753393193266,"sku":"79891859","price":26.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ddc92ffdfb8f4df963b44d6eed887893.jpg?v=1788936191","url":"https:\/\/voomisupply.com\/products\/hertel-79891859-jobber-drill-bit-wire-49-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
