Built from M35 cobalt steel with a bright uncoated finish, this bit features a 135-degree split point that reduces walking on contact and lowers the thrust needed to start a hole. The right-hand spiral flute geometry evacuates chips efficiently during through-hole and blind-hole drilling. With a 1\/16 inch diameter and a 7\/8 inch flute length, this bit is suited for small-diameter work in metal fabrication, HVAC sheet metal, plumbing rough-in, and electrical trade applications where precision entry is required.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is sized for small-diameter holes in ferrous and non-ferrous metals, stainless steel, cast iron, and harder alloys encountered in trade and industrial settings. The jobber length profile balances reach and rigidity for general-purpose use in handheld drills, drill presses, and magnetic base drills. HVAC technicians, plumbers, electricians, and sheet metal workers will find this bit useful for pilot holes, access holes, and anchor point drilling in tight clearance areas. The straight cylindrical shank fits standard drill chucks without adapters.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM35 cobalt steel construction for heat resistance and extended tool life in hard materials\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces bit walking and lowers entry thrust on hard surfaces\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute with regular helix promotes clean chip evacuation\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish allows visual wear inspection during use\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank fits standard drill chucks directly\u003c\/li\u003e\n  \u003cli\u003e1\/16 inch diameter with 7\/8 inch flute length for small-diameter precision work\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose jobber length drill bit compatible with standard three-jaw drill chucks accepting straight cylindrical shanks at the 1\/16 inch diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall into a properly sized drill chuck and tighten securely before use. Use appropriate cutting fluid or coolant when drilling stainless steel or hardened alloys to reduce heat buildup and extend bit life. Secure the workpiece before drilling to prevent movement. Inspect the cutting edges for wear before each use and replace bits that show chipping or bluing at the tip.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1\/16 inch (0.0625 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-7\/8 inches (1.8750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 7\/8 inch (0.8750 inch)\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\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\u003eMaterial\u003c\/strong\u003e: Cobalt Steel (M35)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright \/ Uncoated\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: 0.1 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: 42123\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51738615021874,"sku":"42123","price":36.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6336ed2355f25ef2cf5b7b7132a58fc0.jpg?v=1788801796","url":"https:\/\/voomisupply.com\/products\/hertel-42123-cobalt-jobber-drill-bit-1-16-in-135-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
