Manufactured from M42 cobalt high-speed steel, it handles tough materials including stainless steel, hardened alloys, and structural metals that standard HSS bits struggle with. The bit steps from 1\/8 inch up to 1\/2 inch in diameter, with each step measuring 3\/8 inch in length. The split point tip starts on contact without a center punch, reducing walking on smooth or curved surfaces. The 1\/4-inch round shank with flats seats securely in standard drill chucks and prevents slipping under torque. Electricians, sheet metal workers, and HVAC technicians commonly reach for step bits when sizing knockout holes in enclosures, panels, and sheet metal.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for light-gauge sheet metal, electrical panels, junction boxes, conduit knockouts, and HVAC equipment housings. It covers eight common hole sizes in a single pass, making it practical for field work where carrying multiple twist bits is not efficient. The M42 cobalt composition retains hardness at elevated cutting temperatures, extending service life on abrasive or work-hardening materials. It is appropriate for both corded and cordless drills equipped with a standard 3-jaw chuck.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt construction for high heat resistance and extended tool life in tough metals\u003c\/li\u003e\n  \u003cli\u003eSteps from 1\/8 inch to 1\/2 inch diameter, covering multiple hole sizes in one tool\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch step length provides clean, defined shoulders between sizes\u003c\/li\u003e\n  \u003cli\u003eSplit point tip eliminates center punching and reduces bit walking on smooth surfaces\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch round shank with flats prevents rotation in standard 3-jaw drill chucks\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.5 pounds, well-suited for field carry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 3-jaw drill chucks accepting a 1\/4-inch round shank.

Secure the workpiece before drilling and use appropriate cutting fluid on hardened or stainless materials to extend bit life and reduce heat buildup. Do not apply excessive downward pressure; let the bit cut at a controlled speed to avoid overheating the cobalt tip. Wear appropriate eye protection and gloves when handling metal cuttings.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt (M42)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Hole Diameter\u003c\/strong\u003e: 1\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Hole Diameter\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Round with Flats\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStep Length\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: HOUGEN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 35200\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOUGEN","offers":[{"title":"Default Title","offer_id":51700953907506,"sku":"35200","price":52.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3e2a36e26c6d36636bdd320034e1fe4c.jpg?v=1788395850","url":"https:\/\/voomisupply.com\/products\/hougen-35200-step-drill-bit-1-8-to-1-2-in-cobalt-m42","provider":"Voomi Supply","version":"1.0","type":"link"}
