It is manufactured from high speed steel with a titanium nitride (TiN) coating that extends cutting edge life and reduces friction during operation. The bit is sized to wire gauge 55, which corresponds to a decimal diameter of 0.0520 inches. It features a 118-degree standard point angle and a right-hand spiral flute configuration for efficient chip evacuation. Overall length is 1-7\/8 inches with a flute length of 7\/8 inch. Machinists, maintenance technicians, and trade professionals use this bit for precision hole work requiring small-diameter wire-gauge sizing.\u003c\/p\u003e\u003cp\u003eThis bit is suited for use in benchtop drill presses, hand drills, and CNC applications where close-tolerance small-diameter holes are required. Its straight-cylindrical shank fits standard drill chucks without modification. The general-purpose grade makes it appropriate for light production drilling and maintenance repair operations across HVAC, electrical, plumbing, and mechanical trade applications where wire-gauge holes are commonly needed for fasteners, pilot holes, and instrument ports.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire size 55 (0.0520 inch decimal diameter) for precision small-hole applications\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction with TiN coating for extended tool life\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle with web-thinned, tapered web geometry\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with regular spiral flute for consistent chip removal\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard drill chucks directly\u003c\/li\u003e\n\u003cli\u003eTwo-flute design optimized for general-purpose drilling in a range of materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber-length drill bit fitting any standard drill chuck that accepts a 0.0520-inch straight-cylindrical shank, suitable for drill presses, hand drills, and CNC spindles used across trade and light production applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is installed and removed by a licensed or qualified machinist or trade technician using a standard keyed or keyless drill chuck. Ensure the drill or drill press is fully powered down and secured before changing bits. Use appropriate cutting fluid or lubrication when drilling ferrous metals to preserve coating and edge life. Inspect the cutting edge before each use and replace if chipping or wear is observed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 55\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0520 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiN (Titanium Nitride)\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\u003eFlute Length\u003c\/strong\u003e: 7\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-7\/8 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: 0.0520 inches\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\u003eCoolant Through\u003c\/strong\u003e: No\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\u003eWeight\u003c\/strong\u003e: 0.02 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: 85707792\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51746691875122,"sku":"85707792","price":66.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8a36c797c03fc80496039e3e7f3166dc.jpg?v=1788872829","url":"https:\/\/voomisupply.com\/products\/hertel-85707792-jobber-drill-bit-wire-55-hss-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
