Built from cobalt steel with an oxide and gold coating, the bit delivers heat resistance and extended tool life in demanding production environments. It features a 135-degree split point for fast, self-centering starts without a center punch, and a right-hand spiral flute geometry that clears chips efficiently. Licensed tradespeople and machinists rely on this type of tooling for accurate hole sizing in tight-tolerance applications.\u003c\/p\u003e\u003cp\u003eThis bit is sized at 33\/64 inch (0.5156 inch decimal) and fits within the 0.5000 to 0.6500 inch drill bit size range. It is suited for use in CNC machining centers, drill presses, and hand-held power drills in industrial, maintenance, and fabrication settings. The jobber length format keeps it compatible with standard drill chucks and collet holders across most shop equipment. Typical applications include metal fabrication shops, mechanical contractors, and pipe and structural steel work where consistent hole geometry is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt steel construction with oxide and gold coating for heat and wear resistance\u003c\/li\u003e\n\u003cli\u003e135-degree split point for self-centering starts and reduced thrust force\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with regular spiral flute geometry for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits standard drill chucks and collet holders\u003c\/li\u003e\n\u003cli\u003eFlute length of 4-13\/16 inches (4.8125 inches) provides ample depth capacity for jobber-length applications\u003c\/li\u003e\n\u003cli\u003eNo coolant-through design — standard external coolant or cutting fluid applies\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard drill chucks and collet toolholders accepting straight cylindrical shanks in the 33\/64 inch diameter range, compatible with drill presses, CNC machining centers, and hand-held power drills across common industrial setups.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eA licensed machinist or qualified technician should secure the bit firmly in a properly sized chuck or collet before operation. Power down and de-energize the machine before changing tooling. Apply appropriate cutting fluid or coolant for the workpiece material to extend tool life and maintain dimensional accuracy. Inspect the cutting edges and point before each use and replace the bit if chipping or excessive wear is observed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 33\/64 inch (0.5156 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\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\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003eFlute Length\u003c\/strong\u003e: 4-13\/16 inches (4.8125 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6-5\/8 inches (6.6250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size Range\u003c\/strong\u003e: 0.5000 to 0.6500 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.18 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 42036\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51749283496242,"sku":"42036","price":34.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2a12962d84fc8fc2b31fa1d160a2f3c8.jpg?v=1788904037","url":"https:\/\/voomisupply.com\/products\/hertel-42036-cobalt-jobber-drill-bit-33-64-inch-135-degree","provider":"Voomi Supply","version":"1.0","type":"link"}
