Built from cobalt with an oxide coating, this bit delivers heat resistance and extended wear life in demanding drilling applications. It features a 135-degree standard point angle that reduces walking on entry and requires less thrust than a 118-degree point. The 1\/4-28 threaded shank provides secure, positive engagement in compatible toolholders. The overall length is 2.125 inches with a flute length of 1.25 inches. This bit is typically installed by machinists, maintenance technicians, and trade professionals working in metal fabrication, HVAC equipment assembly, or mechanical service environments.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for use in ferrous metals, stainless steel, and other hard materials where cobalt-grade tooling is required. The 0.246-inch diameter and threaded 1\/4-28 shank make it appropriate for close-tolerance drilling tasks in both production and field repair settings. The spiral flute geometry promotes chip evacuation during through-hole and blind-hole operations. It ships individually and is sold as a single unit.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt construction with oxide coating for heat resistance and extended tool life\u003c\/li\u003e\n\u003cli\u003e135-degree standard point angle reduces bit walking and lowers required drilling thrust\u003c\/li\u003e\n\u003cli\u003e1\/4-28 threaded shank for positive, repeatable engagement in compatible holders\u003c\/li\u003e\n\u003cli\u003eRegular spiral flute promotes efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003e0.246-inch diameter suitable for close-tolerance hole applications\u003c\/li\u003e\n\u003cli\u003eNo coolant-through design — standard dry or cutting-fluid-assisted drilling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with toolholders and drill chucks accepting a 1\/4-28 threaded shank.

Secure the bit fully into the threaded holder to the manufacturer-specified engagement depth before operation. Always wear appropriate eye protection and secure the workpiece before drilling. Do not exceed the recommended RPM range for cobalt tooling in the material being drilled.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.246 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Thread Size\u003c\/strong\u003e: 1\/4-28\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\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 6 x D\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Oxide\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: 0.0286 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 20111614\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: 53384269\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51729171644722,"sku":"53384269","price":16.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7580dfea05663db6f5ed24bbe91b25ca.jpg?v=1788701336","url":"https:\/\/voomisupply.com\/products\/hertel-53384269-threaded-shank-drill-bit-0-246-in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
