The bit measures 33\/64 inch (0.5156 inch) in diameter with a 1\/2 inch straight-cylindrical shank, allowing it to seat in standard 1\/2 inch chucks despite the larger cutting diameter. Overall length is 6 inches with a 3 inch flute length. The 118-degree standard point angle suits general-purpose drilling across a wide range of ferrous and hard alloy workpieces. An oxide straw finish provides mild corrosion resistance and reduces friction during cutting. Right-hand cut with a regular spiral flute pattern for efficient chip evacuation.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for machine shops, maintenance facilities, and fabrication environments where operators are drilling into stainless steel, alloy steel, titanium, and other tough high tensile strength materials. The reduced shank design makes it compatible with common 1\/2 inch drill chucks and drilling machines without requiring a larger chuck capacity. It is a single-piece package intended for professional trade and industrial use, including HVAC fabrication, pipefitting, and structural work where hard-metal drilling is routine.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt tool material for extended performance in tough, high tensile strength materials\u003c\/li\u003e\n  \u003cli\u003eReduced shank design: 1\/2 inch shank accommodates standard drill chucks for a 33\/64 inch cutting diameter\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle for general-purpose drilling and easy center starting\u003c\/li\u003e\n  \u003cli\u003eOxide straw finish reduces friction and provides surface protection\u003c\/li\u003e\n  \u003cli\u003eRegular spiral flute with right-hand cut for efficient chip removal\u003c\/li\u003e\n  \u003cli\u003e6 inch overall length with 3 inch maximum drilling depth\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement or working bit for any drill press, milling machine, or hand drill equipped with a 1\/2 inch chuck.

Secure the 1\/2 inch shank fully in the chuck and verify runout before drilling. Always wear appropriate eye and hand protection when operating drill bits in ferrous or hard alloy materials. Do not exceed the recommended drilling depth of 3 inches for this bit length.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 33\/64 inch (0.5156 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Oxide Straw\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Tough High Tensile Strength Materials\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 pounds\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: 74147422\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51740209381682,"sku":"74147422","price":83.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/36a8f7dbef91127dcd03d22bd3027f7f.jpg?v=1788823529","url":"https:\/\/voomisupply.com\/products\/hertel-74147422-cobalt-drill-bit-33-64-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
