Manufactured from high speed steel with a bright, uncoated finish, it features a standard 118-degree split point and a tapered web with web thinning for improved chip evacuation and reduced thrust on entry. The straight-cylindrical shank and regular spiral fluting make it compatible with standard drill chucks. With an overall length of 1.125 inches and a flute length of 0.3125 inches, this is a small-diameter precision bit suited for light-duty drilling in metals, plastics, and soft materials. Machinists, tool-and-die workers, and general metalworking trades are the primary users.\u003c\/p\u003e\u003cp\u003eThis bit is intended for general-purpose drilling applications where wire-gauge-sized holes are required. Typical uses include pilot hole drilling, precision hole layout in sheet metal, electronics enclosures, instrument panels, and similar light-gauge substrates. The two-flute spiral design handles both hand-held and machine-mounted drill operations. It ships individually but requires a minimum order quantity of 12 units, making it appropriate for shop stock replenishment or production floor use.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire gauge No. 72 size — 0.0250 inch decimal diameter for precision small-bore applications\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction rated for general-purpose drilling in metal and non-metal materials\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle with web thinning for reduced entry thrust\u003c\/li\u003e\n\u003cli\u003eTapered web configuration supports chip flow in shallow-flute geometry\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish — no coating buildup to affect tight-tolerance hole sizing\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, two-flute spiral for use with standard clockwise-rotation spindles\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber-length drill bit for use in standard drill chucks, CNC drilling centers, drill presses, and hand drills accepting straight-cylindrical shanks at the 0.0250 inch diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists or general metalworking trades using any chuck capable of gripping a 0.0250-inch straight shank. At this diameter, secure, centered chuck engagement is critical — use a precision keyless or keyed chuck rated for small-diameter tooling. Ensure spindle speed is set appropriately for the bit diameter and workpiece material before starting the cut. Do not apply excessive feed pressure, as small-diameter HSS bits are prone to deflection and breakage under lateral load.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: No. 72\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0250 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: Bright\/Uncoated\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: 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: 0.3125 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: 0.0250 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.015 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: 84578277\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51738214957362,"sku":"84578277","price":50.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c556e88a68db1192ecf76813ef70752c.jpg?v=1788796849","url":"https:\/\/voomisupply.com\/products\/hertel-84578277-jobber-drill-bit-wire-72-0-025-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
