The bit measures 7\/32 inches (0.2188 inches) in diameter with an overall length of 3.75 inches and a flute length of 2.5 inches. It features a 135-degree split point for fast, self-centering starts that reduce walking and minimize the need for a center punch. The cobalt construction with an oxide and gold coating provides heat resistance and extended tool life under demanding cutting conditions. Right-hand cutting with a regular spiral and straight cylindrical shank. Installed by machinists, maintenance technicians, and trade professionals working with ferrous and exotic metals.\u003c\/p\u003e\n\u003cp\u003eThis bit fits standard drill chucks and is suited for use in drill presses, hand drills, and magnetic drills in both shop and field applications. Its 7\/32-inch diameter places it in the 0.2000 to 0.2500 inch decimal range, making it a common size for tapping clearance holes, electrical conduit work, and mechanical fastener applications. The two-flute spiral design provides efficient chip evacuation during through-hole drilling in metalworking tasks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt construction with oxide and gold coating for heat resistance and extended tool life\u003c\/li\u003e\n  \u003cli\u003e135-degree split point for self-centering starts and reduced thrust\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction with regular spiral flute geometry\u003c\/li\u003e\n  \u003cli\u003eTwo-flute design promotes efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through design — suited for dry or externally lubricated drilling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard jobber length drill bit compatible with any drill press, hand drill, or magnetic drill equipped with a chuck sized to accept a 7\/32-inch straight cylindrical shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall and removal should be performed with the drill powered off and the chuck key fully removed before operation. Use appropriate cutting fluid or lubricant when drilling hard metals to reduce heat buildup and prolong bit life. Secure the workpiece firmly before drilling to prevent movement. Inspect the cutting edges before each use and replace the bit if chipping or dulling is evident.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 7\/32 inches (0.2188 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Oxide and Gold\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\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\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: 0.14 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 41980\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51730333925682,"sku":"41980","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e7cf3e55dea19eb1faaef57975806d57.jpg?v=1788715532","url":"https:\/\/voomisupply.com\/products\/hertel-41980-cobalt-jobber-drill-bit-7-32-inch-135-degree","provider":"Voomi Supply","version":"1.0","type":"link"}
